Elephant Robotics myArm M750

The myArm M750 is a versatile intelligent 6-DOF robotic arm designed by Elephant Robotics as the execution counterpart in the myArm M&C teleoperation ecosystem. The "M" stands for Master, reflecting its role as the primary motion execution device that pairs with the myArm C650 controller for complete teleoperation setups.

With a 750mm horizontal reach, a rated payload of 500g (up to 1kg peak), and a 1-DOF parallel end effector (gripper) included as standard, the M750 delivers the precision and versatility needed for applications requiring complex motion control, accurate positioning, and high programmability.

The M750 is powered by industrial-grade high-precision digital servo motors paired with leading-edge control algorithms, giving it extraordinary torque control and precise positional positioning capabilities. Weighing 3.2kg with a total span of 1,500mm, it is built for scenarios demanding strict operational accuracy, such as precision assembly, fine manipulation, and quality monitoring.

The arm requires a 24V 9.2A power supply and includes an emergency stop switch that must be connected during operation for safe use. Its base uses an M6 flanged mounting system, and the end-of-arm is compatible with LEGO component holes and threaded holes for flexible accessory integration.

A wide range of peripheral accessories extends the M750's functionality significantly. Beyond the standard parallel gripper and optional camera module, users can equip adaptive grippers for complex gripping tasks, suction pumps for handling larger objects, flexible gripping jaws for fragile items, and phone holders for mobile applications.

The M750 excels in education and research environments, particularly for validating kinematics algorithms, conducting ALOHA-compatible end-to-end data training, and performing composite scene application verification. It supports drag-and-drop teaching through the built-in Minirobot software, enabling intuitive motion recording and playback without any programming knowledge.
