Initialize the robot to its initial position before starting the teleoperation.

Initialize Robot

Update the robot position based on the received teleoperation data.

Teleoperation Control

High frequency control of the robot arm via WebSocket connection for real-time updates and commands.

Teleoperation Control (WebSocket)

Move the robot to an absolute position specified by the end-effector.

Move to Absolute Position

Start automatic control of the robot using OpenVLA model outputs.

Start Automatic Control

Stop Automatic Control

Retrieve the position, orientation, and open status of the robot's end effector.

Read End-Effector Position

Read the current torque of the robot's joints.

Read Torque

Enable or disable the torque of the robot.

Toggle Torque

Read the current positions of the robot's joints in radians and motor units.

Read Joint Positions

Move the robot's joints to the specified angles.

Write Joint Positions

Start the calibration sequence for the robot.

Calibrate Robot

Stream video feed of the specified camera. If no camera id is provided, the default camera is used. If the camera id is 'realsense' or 'depth', the realsense camera is used.

Video Feed For Camera
