The bot rides on a rubber coated bowling ball which is driven by three omnidirectional wheels. The robot can not only stand still but also move in any direction.It can work as a mobile tray for objects, supporting platform to help people carry heavy loads.
Its like an inverted pendulum and thus naturally unstable,...Yes Unstable but Thats advantage.....it has a small footprint which gives it the ability to move in any direction without changing its orientation unlke conventional robots.
The robot is about 0.5 meter high and weighs 7.5 kilos. The ball itself is about 3.6-kg bowling ball with a 20 cm diameter and coated with rubber spray.
The control strategy is the same used for other inverted pendulum-type systems. the control system keeps the inclination at zero degrees and keep the ball at the spot spot. If the robot is pushed, it will try to balance itself and return to the original location.
The idea of ball-balancing robots and one-wheeled robots dates back to the 1970s. Today even hobbyists have shown off osam design, and a few large-scale robots have been built in academia. Perhaps the most famous is ballpoint, developed by researchers at Carnegie Mellon.
It's a dynamically stable mobile robot that is tall enough to interact with people.Well Its quite simple to irobots truck where the hero is followed by the truck which has this omidirectional wheels at incredable speeds
I can imagine certain practical application which can be used in carring loads and replacing our wheels in cars and bikes..
