X Square Quantum No.2 (QUANTA X2) Wheeled Humanoid

Overview
Quantum No.2 (QUANTA X2) is X Square's new-generation wheeled humanoid built around the self-developed WALL-A manipulation foundation model (tens of billions of parameters, end-to-end, cross-task and cross-scene generalization). The platform packs 62 total DoF at 164 cm height with a 0-2 m working envelope and 6-DoF torso; each arm reaches 765 mm with +/-0.03 mm repeatability, 1.8 m/s end-effector speed, 6 kg rated and 25 kg max dual-arm payload, terminating in a 2-DoF gripper or 20-DoF dexterous hand. The 2-DoF chassis travels at 1 m/s with 2D LiDAR, 4x ultrasonic, RGBD, 3D-TOF, single-point TOF and IR sensing, targeting home service, research education, commercial cleaning and logistics sorting.
