Using VR Controllers for Robot Teleoperation
Using VR Controllers for Robot Teleoperation VR controllers (Meta Quest, HTC Vive, Valve Index, etc.) have become a popular input device for robot teleoperation, and for good reason: they provide precise 6-DOF tracking, built-in buttons/triggers for gripper control, and an intuitive mapping between human hand motion and robot end-effector motion. This tutorial covers how to integrate VR…
The article discusses the use of VR controllers for robot teleoperation, highlighting their advantages such as precise 6-DOF tracking, built-in buttons and triggers, and intuitive mapping between human hand motion and robot end-effector motion. Compared to other input devices, VR controllers offer direct spatial mapping, sub-millimeter to centimeter tracking accuracy, and stereo visual feedback when paired with a headset display.
However, the added system complexity due to the need for VR runtime and coordinate frame conversions between VR space and robot space is also mentioned. The article provides a step-by-step guide on integrating VR controllers into a teleoperation pipeline, including reading controller pose and input using SDKs like OpenXR, SteamVR, and Oculus/Meta SDK, as well as coordinate frame alignment through a calibration transform.
