Bimanual manipulation
Tasks using both hands together, often with coordinated, asymmetric roles.
Short answer
Bimanual manipulation is any task that uses both hands together, often with asymmetric, coordinated roles — one hand stabilizing while the other acts. It is common in real work and substantially harder to learn than single-hand tasks.
01
Why it matters
Many valuable tasks are inherently two-handed. Training bimanual policies needs data where both hands stay in frame with accurate per-hand pose throughout the coordination, not just one hand at a time.
02
How Firsthand handles it
Firsthand captures both hands in frame with per-hand 3D pose and visibility flags, including long continuous clips of fine bimanual work.
