Quasi-Wireless Capacitive Power Transfer for Wire-Free Robotic Joints

Robotics is a highly active, multidisciplinary research area with a broad list of applications.A large research focus is to enhance modularity in order to expand kinematic capabilities, lower fabrication time, and reduce construction costs.Traditional wiring within a robot presents Porcelain Tag major challenges with mobility and long-term maintenance.Designing robotics without wires would make a significant functional impact.This work presents a new application of quasi-wireless capacitive power transfer that investigates impedance matching parameters over a highly resonant, coupled transmission line to achieve efficient power transfer over a robotic chassis.

A prototype is developed and its BSP operating metrics are analyzed with regard to the matching parameters.
