Giving disabled babies the power of movement could improves their development. But it's the control mechanism on this particular baby robo-chair that's the real genius: by sticking the baby into a seat strapped onto a Wii Fit Balance Board perched atop a Pioneer 3 robot platform, researchers from Ithaca College created a robot that travels in whatever direction a baby leans. From the paper : The balance board has responsive pressure sensors in each of its four corners and built in Bluetooth capabilities. C++ library (ti) to access balance board data within our robotics software. Our software compares the values of the four pressure sensors to determine which, if any, direction the infant is leaning.
