1. A system for charging an autonomous robot, the system comprising:

  • an autonomous mobile device comprisingan undercarriage,a wheel extending from the undercarriage toward a ground surface to support at least a portion of the mobile device above the ground surface, anda detector vertically aligned with the wheel and disposed above the wheel; and

    a stationary charger comprisinga base plate defining a wheel receiver configured to receive the wheel of the autonomous mobile device, the wheel receiver comprising a depression in the base plate,charging contacts disposed along the base plate, wherein;

    the charging contacts are configured to align with corresponding charging contacts on the undercarriage of the autonomous mobile device when the wheel of the autonomous mobile device is disposed in the wheel receiver;

    the wheel of the autonomous mobile device is positionable in the wheel receiver defined by the depression in the base plate to establish electrical communication between the autonomous mobile device and the stationary charger, andthe depression in the base plate forming the wheel receiver is at least partially between the charging contacts and the contacts are elevated relative to the wheel receiver.
