sequence-playback

A Viam module that replays recorded arm demonstrations. Record a demonstration with sequence data capture, then play it back on the real arm (and gripper) at the speed it was recorded.

Useful for VLA demos and learning content: you can show the exact motion a policy is going to learn from.

Models

• devrel:sequence-playback:arm-playback: a generic service. Loads a sequence from Viam Cloud by ID and replays it. Controlled with DoCommand.

Notes

• This module does not record. Use the data manager's sequence capture to record JointPositions on the arm and get_position (via DoCommand) on the gripper.
• The module reads from Viam Cloud using the API key that viam-server gives modules. If you run the binary by hand without those environment variables, play and list will fail with a clear error.
• The first move of every playback goes to the recording's start pose at the arm driver's default speed. Put the arm near that pose before testing on hardware.
