Robot control

Teleoperation

Definition

Teleoperation is the control of a robot by a human operator from a separate location or interface. The operator supplies commands while feedback, such as camera images or the robot's motion, helps them guide the task.

Also known as: Robot teleoperation

A person supplies the actions

Teleoperation keeps a person in the control loop. In the ALOHA 2 system, an operator uses a pair of leader arms to guide a pair of follower robot arms through manipulation tasks. The project also provides a simulation model for collecting demonstrations.

The interface and distance can vary. The defining feature is that a person directs the robot's actions through an interface rather than the robot choosing the entire task on its own.

A way to collect training examples

Teleoperation can produce demonstrations for robot learning. ALOHA 2 was designed to improve the hardware and operator experience used for large-scale two-arm data collection. A learned policy can later attempt similar tasks using that data.

Teleoperated and autonomous demonstrations differ

When assessing a robot demonstration, check who supplied the actions. A person successfully controlling a manipulation task demonstrates something different from a robot completing that task with a learned policy. Training from teleoperated examples does not mean a deployed system is always teleoperated.
