01THE PREMISE

Machines that
have to work.

Human motion, robot motion, and the data between them.

A live visual record of robotics and physical-AI systems in progress.

02CURRENT SYSTEMS
FOUR PERSONAL SIGNALS
01 / 04POST ↗

UMI gripper

Human demonstration → structured robotics data

A tabletop loop connecting gripper opening, camera motion, and object interaction.
POST ↗

Human → ORCA

Retargeting human hand motion to a 17-actuator robotic hand.
