I read about this new WiFi extending robot. Thought I let you guys know about it. Even though it does not lie in the realm of human robot interaction, It is still robotics and pretty cool (since it can climb stairs)! I think Professor Tejada would find it specially interesting as it has a direct application in the disaster environment. You can find the article here. One cool thing that they did was that they are using an html 5 based controller for the robot so that it can be controlled with any device, much like what we are trying to emulate with pleo and scribbler.
