Field notes
A sample task asks the player to dig a trench to depth along a surveyed line, giving each shift a measurable completion target. The example JSON Lines record includes pose, velocity, boom and bucket state, load, task progress, controls, and an 11×11 terrain patch; camera frames are saved every fifth step. The page says session files stay local unless the player chooses to download them.
