LeRobot Dataset with Relative Timestamps
Source: bag_all_0.db3
Episode: bag_all_0 → episode_0
Messages: 300 joint state messages
Duration: 2.989938 seconds (100.3 Hz)
Robot: Dual-arm with 12 joints
RELATIVE TIME CONVERSION
✅ TIMESTAMPS START FROM 0:
- Original absolute timestamps converted to relative
- First frame: 0.000000s
- Last frame: 2.989938s
- Duration: 2.989938s
✅ VISUALIZER COMPATIBILITY:
- Relative timestamps (not absolute Unix time)
- Progressive time for smooth playback
- Proper LeRobot v2.1 format
- Clock synchronization maintained
🎬 SHOULD NOW PLAY in LeRobot visualizer!
Key Fix: LeRobot expects timestamps starting from 0, not absolute Unix timestamps. This dataset converts absolute bag timestamps to relative time for proper playback.
