Robot with interchangeable drive system
A robot comprises a memory, a processor, a body and a drive system which are coupled. The drive system comprises one of auger-based surface interface portions and continuous tread surface interface portions. The auger-based surface interface portions and the continuous tread surface interface portions are interchangeable to adapt the robot to one of different operating conditions and different uses. The processor is configured to: control movement of the robot, via the drive system, to traverse across a first surface, wherein the first surface comprises piled granular material, in response to the drive system being configured with the auger-based surface interface portions; and control movement of the robot via the drive system to traverse across a second surface, which is a solid or semi-solid surface other than the piled granular material, in response to the drive system being configured with the continuous tread surface interface portions.
