Mercury A1

The Mercury A1 is a 7-DOF lightweight robotic arm developed by Elephant Robotics (Shenzhen, China), featuring self-developed 'Power Spring' harmonic modules, carbon fiber construction, and a 3.5 kg net weight. It is designed for educational and industrial applications, supporting ROS/MoveIt/Gazebo/MuJoCo simulation environments and multiple programming interfaces. The arm operates autonomously once programmed — executing pre-defined or learned tasks without a human performing or driving the task — though it requires user setup, programming, and periodic maintenance. Several facts in the extracted dataset (keyboard hardware, synthesizer, outboard motors, Mercury bank, 3D printer mod) are clearly unrelated to the Mercury A1 robot and have been excluded from the reconciled picture. There are minor conflicts in DOF count (6 vs 7) and maximum output torque (20 Nm vs 80 Nm) across sources.
