DroidWorks, the stealth-mode robotics company launched early in 2009 by iRobot co-founder Helen Greiner, has changed its name to CyPhy Works. The Company has also won a US$2.4 million research award from the National Institute of Standards and Technology to study ways of using unmanned aerial vehicles to inspect civil infrastructure such as highways, bridges and dams, according to a story today in Mass High Tech. The grant will allow the company to hire more robotics engineers, Greiner told the publication.
