Abstract: Systems and methods are provided that use a mobile robotic device (120, 220, 800) to transport rechargeable batteries (322, 422, 530, 570, 610, 722) between a base station (110, 600, 700), which charges the batteries, and a battery operated device (130, 230, 300, 400, 500, 550), such as battery powered kiosk (400) or signage system (300), which uses a charged battery as a power source. After traveling to a battery operated device, the mobile robotic device removes any discharged batteries from the battery operated device and installs a charged battery. The mobile robotic device then travels to the base station and attaches the discharged battery to the base station for recharging. The mobile robotic device may be configured to perform other transfers, such as data transfers and paper transfers.
