Patent attributes
A self-propelled robot and method for operating the same are provided. The self-propelled robot includes a base, a drive motor, a communication transceiver, at least two laterally spaced-apart range finding sensors and a processor. The base defines a bottom of a payload receiving space. The drive motor is operable to propel the base across a surface. The communication transceiver is configured to communicate with a carry sensor that is remote from the robot. The range finding sensors are configured to provide range information indicative of a distance between the remote device and the range finding sensors. The processor is configured to, when communication transceiver is in communication with the remote device, operate the drive motor to maintain a predefined distance between the range finding sensor and the carry sensor.
