Abstract

The Zebro is a six legged autonomous robot, designed to be deployed in swarms. Charging the battery is still done manually. To further increase the autonomous abilities of the Zebro, a wireless charging station and module is designed. The charging station is fully modular and interconnected by charging pads. This opens the possibility of charging multiple Zebro's simultaneously. The charging module consists of a receiver and Battery Management System inside the Zebro.

In this thesis, both the transmitter and receiver side of the Wireless Power Transfer (WPT) system is designed. The transmitter and receiver must be perfectly aligned for high efficiency in a wireless charging setup. The positioning of the Zebro is not highly accurate, therefore the design of an inductive WPT system using SS-topology compensation is presented. Also, possible solutions improving the efficiency of the power transfer and the WPT system is proposed in this thesis. These improvements include coil optimization, object detection, circuit damage protection and implementation into the overall system.
