CommercialElephant Robotics Mercury (A1 / B1 / X1): research-grade wheeled humanoid family. X1 trim: 19 DoF, NVIDIA Jetson Xavier (32 TOPS), 1.2 m/s, 8 h battery, dual 7-DoF arms with Power-Spring harmonic modules.
Mercury is Shenzhen-based Elephant Robotics' research humanoid family — built around a universal hardware platform for embodied-AI research. The lineup spans A1 (dual-arm tabletop unit), B1 (17 DoF mobile dual-arm) and X1 (19 DoF on a high-performance AMR base) (elephantrobotics.com).
All three share the Power-Spring harmonic module with brakes and hollow cable routing. B1 and X1 run NVIDIA Jetson Xavier (up to 32 TOPS) for SLAM + path planning + obstacle detection. The X1 hits 1.2 m/s, climbs 2 cm obstacles, handles 15° inclines and runs ~8 hours per charge. The Mercury line is positioned as an accessible research kit, with IEEE Spectrum highlighting it as a popular embodied-AI workbench.

Elephant Robotics Mercury A1: tabletop / desktop research arm with 80 N·m torque, 19-bit encoder, 0.6 arcmin repeatability. Entry tier of the Mercury family for embodied-AI research and education.

Elephant Robotics Mercury B1: stationary research humanoid, 17 DoF dual 7-axis arms, NVIDIA Jetson edge AI, 3D machine vision + voice interaction. Embodied-AI workbench.

Elephant Robotics Mercury X1: wheeled humanoid research platform, 19 DoF, NVIDIA Jetson Xavier (32 TOPS), 1.2 m/s, climbs 2 cm obstacles + 15° inclines, 8 h battery. Top tier of the Mercury family.
