Creating a Robot Sensor Data Recording and Replay System
Every robot learning project eventually needs the same infrastructure: a way to record everything the robot sees and does, and a way to play it back later — for debugging, dataset inspection, offline evaluation, or regenerating labels without touching the physical robot again. This tutorial builds a general-purpose recording and replay system you can drop into any robotics pipeline.
Why You Need This
Recording raw sensor streams alongside your teleoperation or autonomous runs pays off in ways that aren't obvious until you need it:
Debugging policy failures without needing the robot present
