“…Wireless Power Transfer (WPT) could be a possible means to remove wiring within robotic design [1][2][3][4][5][6][7][8]. Researchers have investigated Inductive Power Transfer (IPT), demonstrating a 1 degree of freedom experimentally [9], which was theoretically expanded to 3 degrees of freedom [10]. A major challenge with IPT comes from lower misalignment tolerances between the transmitter (Tx) and receiver (Rx).…”

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 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 operating metrics are analyzed with regard to the matching parameters.
