Overhead autonomous charging moves the entire charging apparatus up and off the floor. Rather than requiring a robot to navigate to a dedicated station, dock precisely, and sit idle, the power comes from above.

The QKOIL™ platform is a patented overhead wireless inductive charging system. Power-transmitting coils are mounted overhead, on ceiling infrastructure, gantries, or existing racking system, while each AMR carries a compact receiver coil on its upper surface. When a robot positions itself beneath an overhead unit, wireless power transfer begins automatically. No cables. No connectors. No human intervention.

This approach supports opportunity charging; the robot tops off its battery during any idle moment beneath the overhead unit rather than making a dedicated trip to a charging station. The result is near-continuous operation with dramatically reduced downtime.
