Facebook wants to patent a self-balancing robot that can switch between having two and three wheels, according to the patent’s application document filed with the US Patent & Trademark office says.
Two-wheeled robots have the benefit of a small footprint but are limited in how much they can carry, so “there is a need for a robot that has both the height of a self-balancing, two-wheeled robot and the load carrying capacity of a three- or four-wheeled robot,” the application says.
