Abstract
This disclosure is generally directed to systems and methods for wirelessly charging a battery in a mobile robot. In an example method in accordance with the disclosure, a mobile robot locates and approaches a wireless battery charging station (by using an onboard camera, for example). The mobile robot then executes an alignment procedure to align a wireless charge receiving pad of the mobile robot with a battery charging pad of the wireless battery charging station. The alignment procedure may involve the mobile robot moving the wireless charge receiving pad in any of three axial directions, such as, backwards, forwards, sideways, upwards, and/or downwards. After alignment is completed, the mobile robot may establish a wireless handshake with the wireless battery charging station. The wireless handshake can include a verification of an authentication of the mobile robot to access the wireless battery charging station, followed by a wireless battery charging operation.
