What is bimanual arm data collection?
Bimanual platforms like ALOHA enable two-arm coordinated manipulation — the hardest class of tabletop manipulation tasks. Both arms must move in precise coordination, mirroring human two-handed dexterity.
Use cases we support:
- Assembly — peg-in-hole, connector mating, multi-part joining
- Cloth folding — garments, soft goods, deformable object manipulation
- Tool handover — passing objects between hands mid-task
- Bimanual grasping — two-arm lifts, stabilize-and-operate tasks
Why teams partner with us:
- 14 bimanual rigs purpose-built for two-arm demos
- 30Hz joint logging across both arms simultaneously
- <8ms bilateral latency — left-right sync without drift
- Operators trained on two-arm coordination, not repurposed single-arm teams
Bimanual coordination is where most tabletop policies fail.
Our rigs are purpose-built for two-arm demos — not adapted single-arm setups. That difference shows in data quality, sync accuracy, and task success rates.

What we capture
What we capture on a bimanual rig
The streams a bimanual VLA or contact-rich policy actually trains on.
Bimanual coordination
Synchronized left and right arm trajectories, joint and end-effector.
Tool-tip pose pairs
Per-arm TCP pose in your robot frame, calibrated per session.
Contact force profiles
Wrench data from each arm, time-aligned for two-handed contact-rich tasks.
Synchronized video
Wrist cameras on both arms plus scene cameras, frame-perfect.
How we integrate
From dual rig to production
A four-stage integration designed around bilateral teleop latency budgets.
Rig calibration
Both arms calibrated together. Bilateral latency measured and locked.
Bimanual training
Operators trained on coordination patterns specific to your task.
Production capture
Trajectories captured with daily QA on coordination quality.
Force and video sync
Force sensor and multi-camera streams aligned per session.
