Abstract
Techniques for wirelessly charging small power receiving units are disclosed. An example power receiving unit includes a transportation mechanism to enable the power receiving unit to move and a wireless communication system that enables the power receiving unit to communicate with a plurality of other power receiving units. The power receiving unit is a master unit and the other power receiving units are nodes that take commands from the master unit. The power receiving unit also includes a controller to command the nodes to form a composite receive coil over a power transmitting unit and communicate with the power transmitting unit to start a charging session.
