A team of researchers, in 2009 developed the prototype of a motorized wheelchair in order to provide “safe powered mobility to infants with physical disabilities who are less than two years of age.” IC Tots on Bots is a collaborative research project among the departments of Computer Science, Occupational Therapy and Physical Therapy at Ithaca College in New York.
The balance board has responsive pressure sensors in each of its four corners and built in Bluetooth capabilities. They are using a commercial Bluetooth adapter and WiiYourself! C++ library to access balance board data within our robotics software. Their software compares the values of the four pressure sensors to determine which, if any, direction the infant is leaning. When a sustained lean is detected, the robot begins to move in that direction. When the child reaches out for an item, he or she leans in the direction of the item and moves towards it. We believe this will be the most intuitive method for a young child to learn to use.
Because each child moves differently from any other, the researchers are working on creating parameter files that are tailored to the individual. In addition, the Pioneer 3 robotic platform uses sonar to keep from bumping into objects, which helps keep babies safe from collisions. For ultimate peace of mind, there is also a remote-control joystick that provides wireless parental override.
It is great when people think outside the box and apply different technologies to create new solutions that may improve people's lives. This should be a great tool in schoos and therapy centers to help children to move through space, increase development and improve independence.
