Teleoperation Indirect Control Methods For Autonomous

Dec 21, 2020 Indirect control is a method that eliminates the need for direct commands. Instead, it allows a remote operator to issue commands at a higher level of abstraction, including Follow this path or Stop and wait, and allow the vehicle to execute the action by itself. It is shortsighted to think of only direct control for teleoperation.
