Optimus units leverage Tesla's self-driving perception stack to navigate the rework zone, while force sensors in the hands prevent over-tightening. Technicians issue commands through voice prompts linked to Tesla's internal service AI.

The company says Optimus reduced cycle variability on rework stations that require awkward reaches. By logging torque and fastener data automatically, the humanoids create compliance records for regulators and warranty teams.

Tesla is retraining Optimus on new tasks weekly through imitation learning using internal teleoperation rigs. Executives say the robots will expand to battery module assembly once safety reviews conclude.
