Key Engineering Highlights
- Breaks the $25,000 price barrier for true 165cm adult-height humanoids (¥158,000 / ~$21,900)—giving university labs and VLA startups dual 7-DoF arms and a 3-DoF waist instead of child-sized 130cm frames
- Pairs head-mounted and chest-mounted Intel RealSense D435i RGB-D cameras with swappable parallel grippers or multi-finger dexterous hands for bimanual tabletop manipulation
- Opens low-level joint-torque control, URDF digital twins, and Python/ROS 2/Isaac Lab sim-to-real pipelines across RK3588 and 275-TOPS Jetson AGX Orin compute modules
