Robots that can stand and walk under their own volition are nothing new. We've seen plenty of robots that can run around, do acrobatics, and even teach college classes. But this one is different. The Ballbot is able to balance itself on one ball, moving around slowly and even staying upright when getting pushed around. The amazing balancing machine was developed by researchers at Carnegie Mellon University as a new way of having robots interact with people. While most robots have either clunky legs or a wide wheelbase, the Ballbot can roll itself around any flat surface easily, without taking up space or needing lots of room to get around. One can imagine a Ballbot serving drinks at a fancy party, rolling from guest to guest smoothly without knocking any tables over. This technology is still in relatively early development, but it seems to be a huge step forward in robotic movement and will probably find its way into many new robotic devices in the future.
