What’s inside
The parts the company has talked about publicly.
- Hands
- none
- Movement
- Walks on legs · 25 joints
- Actuators & motors
- 25 joints: 6 per leg, 2 per shoulder, 3 neck, plus jaw, eyebrow and 4 mechanical eye axes; Unitree and Dynamixel actuators. Asymmetric 6-DoF legs (one inverted) hidden under the skirt; spherical five-bar shoulder linkages and four-bar jaw and eyelid linkages.
- Sensors & vision
- IMU fused with actuator readings in a state estimator.
- Compute
- Three on-board computers; policies trained in Isaac Sim on a single RTX 4090 in about two days.
- Materials & build
- Polyurethane-foam skirt and snowball feet; four-way stretch fabric costume with semi-rigid boning, held on with magnets and snaps; iridescent fibres in the 'snow'. Removable carrot nose.
- AI & software
- Reinforcement learning (PPO) with separate walking and standing policies guided by animation; rewards cut footstep noise by 13.5 dB and keep neck actuators under 80 C using a thermal model. Show functions (arms, eyes, jaw) use classical control. Disney contributed its Kamino simulator to the Newton framework with NVIDIA and Google DeepMind.
- Other details
- 88.7 cm without hair, 14.9 kg. Can speak and converse. Press previews were operator-controlled; in the park it relies on human supervision, with a same-size puppet as a fallback.
