myArm 300 Pi from Elephant Robotics is a seven-axis robotic arm powered by a Raspberry Pi 4B with a customized Ubuntu Mate 20.04 OS, requiring no external PC. With 7 degrees of freedom surpassing typical 6-DOF robots, it supports movements as flexible as a human arm with advanced elbow joint posture changes. It is 100 percent compatible with myCobot accessories and designed for robotics education, control logic teaching, motion path planning, redundancy management, kinematics, and ROS development.
