Real footage. Real Ultra.
Every clip is the actual robot, filmed by its maker, Unitree.
Built like an athlete.
Ultra moves through angles a person can’t: its waist turns 155° each way and its knees bend to 165°. Strong enough to kick, spin and stand itself up.
90 N·mat the knee
Engineering you can see.
Crossed roller bearings, dual encoders on every joint and wiring routed inside hollow joints. Nothing snags, nothing shows.

It reads the room.
A 3D LiDAR and a depth camera map everything around it, so it walks through a crowd without missing a step.
Folds to 69 centimetres.
Ultra folds down to 690 × 450 × 300 mm. Swap its quick-release battery and it runs another two hours.
