## Dimensions and Weight

The robot stands 1.32 m tall, 0.45 m wide, 0.20 m thick when upright, folding to approximately 0.69 m for transport. It weighs roughly 35 kg including battery and features industrial-grade crossed roller bearings at joints.

## Degrees of Freedom (DOF)

The Ultimate configuration provides up to 43 total DOF: each leg has 6 DOF, the waist includes 3 DOF, and each arm features 2 wrist axes plus a dexterous hand with 7 DOF. This contrasts with the base model's 23 DOF.

## Actuators and Power

Joint motors are permanent magnet synchronous motors (PMSMs). Knee actuators deliver up to 120 N·m of torque, exceeding the base model's 90 N·m. Each arm can handle approximately 3 kg loads. The 13-cell lithium-ion battery (9000 mAh) provides roughly 2 hours of operation per charge and features quick-release capability.

## Onboard Computing

An 8-core CPU handles real-time control. The EDU Ultimate includes an NVIDIA Jetson Orin module rated at 100 TOPS for AI tasks including vision processing and speech recognition. Connectivity includes Wi-Fi 6 and Bluetooth 5.2 with over-the-air firmware updates.

## Sensor Suite

- Depth camera for forward visual perception
- Top-mounted 3D LiDAR for 360-degree spatial awareness
- Four-microphone array with noise cancellation
- 5W speaker for audio output
- Dual joint encoders per joint
- Inertial Measurement Unit (IMU)
