Cover Story: Power management is a commonly cited issue when implementing underground sensor installations. Prior works have proposed wireless inductive power transfer as a potential solution, but localizing the underground hardware and maintaining power transfer system alignment remain persistent challenges. This paper presents an automated methodology for aligning inductive power transfer coils using agricultural vehicles, robotic actuators, and machine learning methods. This approach was successfully implemented with a buried soil sensor network and wheel line irrigation system at an agricultural test farm. During testing, this automated approach to power delivery was able to rapidly align the aboveground power transfer hardware within 1 cm of peak lateral alignment and deliver over 7.5 W to the underground installation.
