Ghassan E. Jabbour is a University of Arizona professor developing an inkjet printing process that produces photovoltaic devices such as solar cells. He uses digitized images on a computer and sends them to a printer that sprays an organic solution onto an electrically conductive surface. He describes the printed product as a self-illuminated photograph. "The new process uses inkjet to vary the conductivity of the conductors," says Jabbour. "Basically, we design an electronic circuit, scan it to a computer, then send it to the printer." He programmed the printer to interpret colors and convert them to particular chemicals that produce predetermined reactions. "We do some chemistry that allows us to control where we want a lot of electrons and where we don't want electrons." His self-illuminated photographs print in visible colors, but he can also print in colors in the infrared wavelength range that are invisible to the naked eye. For more information, go to www.ua.edu.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
The DDV-IP is a two-wheeled self-balancing robot that can deliver cold beverages to thirsty folks on hot summer days. A wireless RF remote enables manual control of the device beyond the act of self-balancing. All of the features of the DDV-IP result in an effective delivery vehicle while providing entertainment to the user.
Eric Doster of iFixit talks about the most surprising aspect of the Microsoft Surface Pro 3 teardown. In a presentation at Medical Design & Manufacturing Midwest, iFixit gave the Surface Pro 3 a score of one (out of a possible 10) for repairability.
