The myArm C650 is a universal 6-DOF (Degrees of Freedom) robot motion information collection device developed by Elephant Robotics. The "C" stands for Controller: rather than acting as a payload-bearing arm, it functions as a master teleoperation controller and data collector that you move manually by hand to drive other execution robots in real time.
Equipped with a fingertip controller and custom smart buttons at the end, it outputs joint angles or endpoint coordinates at high speeds, making it an essential hub for robotics research, teleoperation, ALOHA-style AI imitation learning, and kinematic algorithm validation.
Key Applications and Functions
- Universal Teleoperation Hub: Functions as an intuitive teach pendant to remotely control execution arms such as the myArm M750, myCobot Pro 630, and Mercury X1 dual-arm humanoid robot.
- High-Speed Data Collection: Streams motion data (position, velocity, coordinates) at 50Hz or higher, providing essential dataset generation for AI training and machine learning models.
- Human-Arm Movement Simulation: The 6+1 axis flexible joint structure accurately mirrors human arm and hand motions for versatile multi-angle control.
- Algorithm Validation and Teaching: Serves as a hands-on tool for educational institutions and research labs to test inverse kinematics and teleoperation control algorithms.
