Key Engineering Highlights
- Second-generation FSA 2.0 integrated actuators deliver up to 380 N·m peak hip torque with dual absolute magnetic/inductive encoders for high-precision joint tracking
- 12-DoF dexterous hands integrate 6 multi-taxel tactile pressure sensor arrays across fingertips and palm to sense grasp force and object geometry in real time
- Serial-parallel hybrid leg kinematics and flattened internal cable routing simplify URDF/MJCF Sim-to-Real transfer in NVIDIA Isaac Lab, MuJoCo, and ROS 2
