Printing a leader–follower pair for a few hundred dollars and collecting teleoperation data for imitation learning.

How we work with robotic arms

Robotic arms are the fastest way into physical AI. We build leader–follower setups that collect human demonstrations, train imitation-learning policies on them, and integrate humanoid arms for contact-rich work.

Leader–follower teleoperation rigs
Imitation-learning datasets and policies
Pick-and-place and assembly prototypes
