# LoopNav

LoopNav contains navigation trajectories for three path types: TURN, ABA, and ABCA.

The trajectory manifests are provided as train.csv, val.csv, and test.csv. The radius
column is intentionally typed as a string because ABA/ABCA use numeric radii while TURN uses
angular ranges such as 60-90 and 90-120.

Trajectory videos and JSON annotations are packaged into per-biome tar archives under TURN/,
ABA/, and ABCA/.
