Magnetically-retained recharge cartridge

Abstract:

Embodiments herein described a replaceable recharge cartridge that is coupled between a charge port of a robot and a charging station. Instead of mating the charging station directly to the charge port in the robot, the recharge cartridge can instead be inserted into the charge port and serves as an interface between the robot and the charging station. As such, the wear and tear occurs on the recharge cartridge rather than the charge port of the robot. In one embodiment, the recharge cartridge is magnetically attached to the charge port for easy installation and removal. The recharge cartridge includes a ferrous slug that is attracted to a permanent magnetic disposed in the charge port. The magnetic attraction between the permanent magnetic and the ferrous slug aligns and connects the recharge cartridge to the charge port.
