BrightSource Energy, a Google.org backed startup we covered a few weeks back, opened their Solar Energy Development Center in Israel this week, and it features an enormous test plant that looks as improbably perfect as a rendering.
The tower in the distance of this picture stands 180 feet tall and is surrounded by 1,600 mirrors that focus the sun’s rays onto the commercial boiler that sits atop the tower. In a real plant that boiler’s steam output would be used to generate electricity with a turbine, but the company didn’t put a turbine in the test facility. BrightSource estimates that a plant this scale could generate 1,500 kilowatts of power.
PG&E, the northern California utility, has agreed to buy 900 megawatt of electricity from the company, and they recently announced a $115 million round of funding.
A host of solar thermal companies are racing to construct pilot plants as a step towards commercializing their various solar concentrating technologies. For more background on the technology and various industry players, check out our previous solar thermal coverage here, here, and here.
There are a couple more awesome pictures after the jump.
Magnetic Resonance Imaging (MRI) revolutionised the medical world two decades ago, providing doctors with an unparalleled view inside the human body. Now, MRI-MARCB has taken MRI to a new level with a system that enhances image quality, reduces scan time and improves diagnosis. Currently in use in several hospitals around the world, the MRI-MARCB system overcomes one of the principal problems in producing MR images of the brain and heart: movement.
“Though MRI is an excellent non-intrusive imaging modality with excellent soft tissue contrast it is susceptible to motion because it can take several seconds or even minutes to acquire an image,” explains Kay Nehrke at Philips Medical Systems in Germany, coordinator of this IST-programme funded project. “During that time the patient’s heart is beating and they’re breathing – it’s like taking a photo of a moving object. If the photo takes one second the image will appear blurry. If you follow the object with the camera, however, you’ll get a clear image and that is what we’ve done in a sense.”
The project partners used two different but complimentary techniques to overcome the motion problem. In the case of heart scans a software system was developed to create a mathematical model of the pattern of movement caused by breathing and heart beat. That information is then used to compensate for the motion effects in the resulting MR image. For brain scans, where even the slightest movement of a patient’s head could cause images to be unusable, a camera system was employed alongside the software to track and compensate for motion.
“Without compensation images can be filled with artefacts, making it hard to tell whether you are looking at a clogged artery or just a poor image,” Nehrke says.
With the MRI-MARCB system image quality is greatly improved resulting in more precise diagnosis, while at the same time reducing the time it takes to perform an MRI scan.
“Trials at 10 hospitals with around 200 patients showed a 30 per cent reduction in scan time because of the compensation for movement,” Nehrke notes. “As we all know time is money so this offers important cost savings for hospitals, while patients feel more comfortable because they do not have to worry so much about not moving or even breathing.”
According to the project coordinator, the software can be easily integrated into existing MRI platforms, and the camera system is “relatively inexpensive given the advantages it provides.”
MRI-MARCB is currently being used at hospitals in Germany, Denmark, Japan and the United States, with the project partners planning further commercialisation activities and development in the future.
A fully digital 4D ultrasound system is set to provide a ‘next generation’ integrated solution for medical imaging applications, allowing practitioners to provide faster treatment and improve therapeutic success rates. Developed by ADUMS, an IST-funded project that ended in April 2005, the advanced high-quality imaging system will significantly reduce diagnostic time. In addition, the technology uses off-the-shelf computer hardware, making it a much cheaper alternative to expensive, purpose-produced ultrasound machines.
“The whole process of ultrasound devices has been moved away from the traditional hardware and is now implemented in software,” says Dr Georgios Sakas, ADUMS project coordinator. “The hardware of the device creates mechanical waves and receives the echoes. Once the echoes are received, they are converted in digital form and the rest of the processing is performed by software.”
A 4D ultrasound takes multiple images in rapid succession, creating a three-dimensional motion video, which is invaluable for diagnosis purposes.
An important factor in ultrasound image processing is the beamformer, the part of the system that provides the focusing for the ultrasound beam.
Dr Stergios Stergiopoulos, president of the Canadian National Medical Technologies, one of the project partners, maintains that even today’s most advanced state-of- the-art medical ultrasound imaging systems suffer from very poor image resolution.
“This is the result of the very small size of deployed arrays of sensors and the distortion effects by the influence of the human body’s non-linear propagation characteristics,” he says. “The ADUMS project technology replaces the beamformer of the ultrasound systems with the adaptive beamforming scheme that has been developed for the sonar array systems of the Canadian Navy. The ADUMS project results demonstrated that the new adaptive beamformer significantly improves, at very low cost, the image resolution capabilities of the ultrasound imaging systems, which will result in better diagnosis.”
Until now, every new generation of the hardware component of ultrasound devices was, effectively, a complete redesign.
“On the other hand, ADUMS technology is based on a complete software approach, using off-the-shelf PC components,” explains Dr Sakas. “Thus, a redesign from scratch will not be necessary and future improvements can be made by extensions of existing software.”
The portability and the low cost of the 4D ultrasound systems allow medical practitioners and family physicians to have ready access to diagnostic imaging systems on a daily basis and will make a valuable contribution in the field of preventive medicine, adds Dr Stergiopoulos.
Consortium partners are currently using the new technology for their businesses and are promoting it to other organisations that use ultrasound technology.
European researchers developed technology that enables a robot to combine data from both sound and vision to create combined, purposeful perception. In the process, they have taken the field to a new level. Currently, computer vision is good at recognising objects in images and videos and has been successfully employed in several specialised industrial applications, such as quality control during microchip fabrication.
But robotic perception is much weaker in less defined situations, like understanding and responding to human behaviour and even conversations. Yet, it is precisely this sort of interaction which promises the most compelling applications for future humanoid technology, where people-like robots can act as guides, or mix with people, or use perception to infer appropriate actions.
More importantly, these broad robotic applications will deliver insights into other disciplines, like cognition and neuroscience.
A truly perceptive robot, capable of acting independently and appropriately in complex situations remains a distant goal, but European researchers brought it much closer with their Perception-on-Purpose (POP) project.
Original, by design “The originality of our project was our attempt to integrate two different sensory modalities, namely sound and vision,” explains Radu Horaud, POP’s coordinator.
“This was very difficult to do, because you are integrating two completely different physical phenomena,” he adds.
Vision works from the reflection of light waves from an object, and it allows the observer to infer certain properties, like size, shape, density and texture. But with sound you are interested in locating the direction of the source, and trying to identify the type of sound it is.
Tricky issue On its own, sound is difficult to pinpoint, because it needs to be located in a 3D space. Then there is the problem of background noise, such as an open window letting in sounds from next door.
But it turned out that integrating two different senses helped the researchers in their bid to locate and tune into relevant sounds.
“It is not that easy to decide what is foreground and what is background using sound alone, but by combining the two modalities – sound and vision – it becomes much easier,” reveals Horaud.
“If you are able to locate ten sound sources in ten different directions, but if in one of these directions you see a face, then you can much more easily concentrate on that sound and throw out the other ones.”
Integrated technology This was one approach that the team took and, with the algorithms they developed, their robot, called Popeye, was able to identify the speaker with a fair degree of reliability.
“There is more work to be done on that aspect of the work, it is not completely robust yet,” warns Horaud.
Still, it was a very strong result, and what makes it even more impressive is that the team managed to integrate all the technology into a neat and compact robotic platform.
“Most often, sound research is conducted in specialised labs, with arrays of microphones and a very controlled acoustic environment. But we integrated our two microphones and two cameras onto the head of our Popeye. The idea is to have an agent-centred cognitive system,” Horaud stresses.
Powerful technology The Popeye packs a lot of powerful technology into a small space and offers purposeful robotic perception. This is important because Horaud argues persuasively that, in evolutionary terms, multi-sensory perception and cognition are linked.
By perceiving a hand-held object with their two eyes, for example, monkeys – and the first hominids after them – developed stereo vision and hence were able to learn many properties of an object from combined tactile and visual data. Over time, they developed new skills, including building tools, from this information.
Horaud feels, too, that some modern uses of artificial intelligence (AI), like chess applications, are limited because they do not learn from their environment. They are programmed with abstract data – say, chess moves – and they process that.
“They cannot infer predicates from natural images; they cannot draw abstract information from physical observations,” he stresses.
For now, POP has achieved many of its aims and developed very promising approaches. Commercial applications for this type of technology are not out of the question, and the researchers also hope to continue their work in a further project.
That project would look at extending some of POP’s results into a functioning humanoid robot. In the meantime, POP’s work means that the purposefully perceptive robot has become a not-so-distant future technology.
The POP project received funding from the Sixth Framework Programme for research.

Pleo is a new type of autonomous life form: a scientifically accurate dinosaur. Pleo looks, moves, sounds and behaves like a living creature. Fully aware and cognitive, he explores his environment and interacts with people, accessories and other Pleo dinosaurs.
Equipped with senses for sight, sounds and touch, Pleo processes numerous stimuli before expressing himself. He feels joy, sorrow, anger and annoyance with realistic dinosaur sounds. And when he's tired, Pleo gets drowsy and sleeps -- sometimes even dreams.
Pleo's sophisticated sensory system consists of nearly 40 devices that enable him to see, sense, touch and detect objects in order to move autonomously and explore his environment without requiring any remote control. This robotic dinosaur includes a color camera with a white-light sensor that allows him to detect bright light from dark, see colors, detect motion, track a moving object, and perceive objects in front of him. This unit also includes microphones on the left and right that give him stereophonic hearing, allowing him to detect sound direction and loudness through both ears. An infrared receiver and transmitter allows Pleos to identify, communicate and interact with one another, while another infrared interrupter allows Pleo to detect when something is being placed in his mouth. Meanwhile eight touch sensors on his chin, shoulder, legs, back and head are triggered by touch and allow him to "feel." This dinosaur has skin that is constructed of a custom-formulated, soft thermoplastic material that's painted with an incredibly realistic and lifelike coloration.
The Pleo Life Form has over 100 custom-designed gears, and 14 motors for highly-articulated movement. Each motor has a force feedback sensor that makes them sensitive to forceful grabs at the dinosaur's legs, neck, tail and torso, causing him to shut down during trauma to avoid internal damage. Pleo will actually react to being hurt, perhaps exhibiting a limp, and can recover over time depending on the level of nurturing you exhibit. Ground sensors allow Pleo to know when a foot is on a solid surface or when he has been picked up, while tilt and shake sensors allow him to know if he has fallen or is being held upside down. The sensors will also wake him up after he has "fallen asleep." Front and rear speakers enable Pleo to communicate via cute honks and hoots, as well as other fun and natural sounds.
Pleo has two 32-bit microprocessors for central and image processing, and four 8-bit sub-processors for motor control. This robotic life form also has multiple built-in data ports, including a mini USB port for online downloads, an SD card slot for Pleo add-ons, and the infrared transceiver that allows Pleo-to-Pleo communications.
Just like a real animal, his behavior cannot always be predicted. Pleo has internal motivations to eat, drink, rest, seek social interaction and more.

Long before TV shows like BattleBots, there were these guys: two plastic boxers battling it out in a ring, tirelessly jabbing at each other. Years go by and these fighters are still at it, still operated by two players working simple controllers, and still madly punching in an effort to knock loose the other fellow's spring-loaded head.
Muscle Wires are thin strands of a special nickel-titanium alloy that actually shorten in length when electrically powered. They are easy to use, and they can lift thousands of times their own weight. The direct linear motion of Muscle Wires offers experimenters a source of motion that is very similar to that of a human muscle, providing possibilities not available with motors or solenoids. This is an ideal material for making small, simple walking robots! Compared to motors or solenoids, Muscle Wires (also known as nitinol) have many advantages: small size, light weight, low power, a very high strength-to-weight ratio, precise control, AC or DC activation, long life, and direct linear action. These features let you create whole categories of amazing new devices that would be difficult or impossible to do with anything else.
Luckily for us robot hobbyists, there are great books available about making nitinol powered walking robots. The best part is that each of these books comes with all of the nitinol you need to make your own walking robot! Take a look at each book to see which one is best for you.

A little history Way back cica. 1987 I decided building a robot would be a way cool idea. I set out building a beast of a brain for my creation. I put together the excellent Talking Electronics TEC-1B Z80 based computer. After weeks of building and testing (I was only 13!) I had it up and running. Ah, those were the days, programming a Z80 in hex... So my Dad helped me put together an aluminium light weight frame. It was slightly modelled on the old Hero robot from Heathkit. Luck was not on our side, and Robbie Mk I got destroyed before he every really came into being. A non fatal car accident saw Robbie Mk I thrown from a trailer - ending up in pieces all across the highway. The electronics were not hurt, but the shell was destroyed beyond recognition. So died the dream of Robbie Mk I.
Many years later the idea of building a robot again seemed like a good idea. This time I began experimenting with the PIC series of microchips, namely the very popular 16F84. Again my father came to the rescue with his woodworking skills and built me a platform on which we mounted some geared motors. I still laugh thinking back how i tried to control the motors using a complex array of relays to change the current direction. You should have seen the sparks fly! I was truely a happy man the day I discovered what an H-brige was :)
So Robbie Mk II was born, on a chipboard base with 2 geared motors. I got it to the stage where it could drag itself *very* slowly around the room aided by an infrared proximity detector circuit. I have a few old photos of the base which i will upload in the coming weeks.
My brother having declared Robbie Mk II as being an insult to the eye offered his services as a model builder. He came up with the stunning design you see below.
The motorized platform for Robbie III is almost complete.
Over the Christmas break i will start adding the electronics.
The under belly. A big thank you to brother Nathan for his tireless work in getting the platform up and running. As you can see the boy has got skills!
I plan to add the electronics in the following order: PIC 16F877A (20MHz) based main controller. An Olimex prototyping board. 2 x SRF08 Range Detectors. MD22 Motor Controller. A Knight Rider LED scanner to make it look pretty. SP03 Text to Speech module. Amplifier for loud speech. CMUCam camera tracking system. Voice Extreme Speech Recognition Module.
Keep checking back here - as i add electronics i'll update the photos.
Sinewinder is an attractive, easy to use lighting system for your R/C vehicle. Just plug the Sinewinder light into a spare receiver channel, or use a separate 5V source.
Sinewinder has 12 bright LEDs that scan from side to side, with a short trail after the leading light. The lights can be switched on and off by using your radio. If no signal is present or the signal wire is cut, the lights will default to being on.
Specifications
Input voltage: 3V to 6V Current draw: 30mA max 4" / 10cm long
Overview The USB-RLY08 provides eight volt free contact relay outputs with a current rating of up to 1Amp each. It is powered from any standard USB bus and has an exceptionally low maximum current consumption of approx. 90mA with all relays on. The relays are SPCO (Single Pole Change Over) types. The normally open, normally closed and common pins are all available on the screw terminals.
LED indication The USB-RLY08 provides a red LED mounted immediately next to each relay to indicate whether it is in a powered state (LED on), there is also two LED's which will flash with USB transactions to and from the module, green indicating reception of data from the PC and yellow the transmission of data to the PC. Finally there is red power LED mounted on the opposite side of the board to the USB connector.
Relay power rating If the contact load voltage and current of the relay are in the region enclosed by the solid and dotted lines in the figure below, the relay can perform stable switching operation. If the relay is used at a voltage or current exceeding this region, the life of the contacts may be significantly shortened.
First Step - Get The Drivers The USB-RLY08 module uses the FTDI FT232R USB chip to handle all the USB protocols. The documentation provided by FTDI is very complete, and is not duplicated here. Before using the USB-RLY08, you will need to install FTDI's Virtual COM Port ( VCP ) Drivers. These drivers appear to the system as an extra Com Port ( in addition to any existing hardware Com Ports ). Application software accesses the USB device in the same way as it would access a standard Windows Com Port using the Windows VCOMM API calls or by using a Com Port Library. Drivers are available for Windows, Apple, Linux and Open BSD systems directly from the FTDI website. You should get and install the drivers now, before you connect the USB RLY08 to your computer. The Drivers page is here.
Which COM port? After installing the drivers, and plugging in the USB-RLY08 module to a spare USB port, you will want to know which COM port it has been assigned to. This will vary from system to system depending on how many COM ports you currently have installed. To find out where it is, right click on your "My Computer" desktop icon and select the "Device Manager" tab. Now scroll down and open the "Ports (COM & LPT)" tab. You should see the USB serial port listed - COM2 in the example below. If you want to change the COM port number - just right click on it, select properties, select advanced and select the COM port number from the available list. The COM port should be set up for 19200 baud, 8 data bits, no parity and two stop bits.
Commands The USB-RLY08 operates with an easy to use command set as described in the table below. Most commands are only a single byte and if applicable the USB-RLY08 will automatically send its response. The only exception to this being the "Set relay states" command which requires and additional desired states byte to be sent immediately after the command byte.
Test program and example source code
To get the USB-RLY08 up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.
Overview The RLY08 provides eight volt free contact relay outputs with a current rating of up to 1Amp each. It requires a 5v supply and has an exceptionally low maximum current consumption of approx. 100mA with all relays on. The relays are SPCO (Single Pole Change Over) types. The normally open, normally closed and common pins are all available on the screw terminals.
Relay power rating If the contact load voltage and current of the relay are in the region enclosed by the solid and dotted lines in the figure below, the relay can perform stable switching operation. If the relay is used at a voltage or current exceeding this region, the life of the contacts may be significantly shortened.

Description Sabertooth 2X5 is the motor driver of choice for small differential-drive robots. It is ideal for smaller robots- up to 3lbs in combat or 25 lbs for general purpose use. It is also a great choice in any application where you need to control two brushed motors.
Out of the box, the Sabertooth can supply two DC brushed motors with up to 5A each continuously. Peak currents of 10A are achievable for short periods. Because Sabertooth 2x5 incorporates soft current limiting and thermal protection, you need not worry about killing the driver with accidental stalls or by hooking up too big a motor.
Sabertooth allows you to control two motors with: analog voltage, radio control, serial and packetized serial. You can build many different robots of increasing complexity for years to come with a Sabertooth. Sabertooth has independent and speed+direction operating modes, making it the ideal driver for differential drive (tank style) robots and more.
The operating mode is set with the onboard DIP switches so there are no jumpers to lose or complicated programming sequences. Sabertooth features screw terminal connectors - making it possible for you to build a robot without having to solder.
Sabertooth is the first synchronous regenerative motor driver in its class. The regenerative topology means that your batteries get recharged whenever you command your robot to slow down or reverse. Sabertooth also allows you to make very fast stops and reverses - giving your robot a quick and nimble edge. In certain operating modes Sabertooth can process up to 3000 speed commands per second.
Sabertooth has a built in 5V BEC that can provide power to a microcontroller or R/C receiver. It also features a lithium cutoff mode allowing Sabertooth to operate safely with lithium ion and lithium polymer battery packs - the highest energy density batteries available.
Sabertooth's transistors are switched at ultrasonic speeds (32kHz) for silent operation.
Use of our motor drivers with cheap AC adapters is not recommended. Use a battery or at least put a battery in parallel with a DC supply.

Go inside the creative world of the R2 Builders Club thanks to an extensive profile in the May 2008 issue of Servo magazine for the robot innovator.
Craig Smith advises prospective members about the amount of time it takes to create a droid: “R2 built from scratch or built from club parts is not a quick project. It will take months to complete a static, non-moving display — even years for a motorized version. When I look at the parts on my droid, I recall the week it took to make the shoulders, the days it took to make the ankle covers, the days it took to re-make the ankles themselves because I did not offset them correctly. And there are dozens more parts on the droid with similar memories. A project such as this is a huge commitment!”
