Robotic Arm

An arm-shaped robot made of joints and links, with a gripper or tool mounted at the end.

A robotic arm is a chain of links and joints with a fixed base and an end effector, such as a gripper, suction cup, or dexterous hand, at the tip. Six degrees of freedom are enough for the end effector to reach any position and orientation in space, while a 7-DoF arm has one redundant joint, letting it work around obstacles. Arms split broadly into industrial arms, built for speed and precision and typically fenced off from people, and collaborative arms, which add force sensing and are designed to work alongside people. Most manipulation tasks studied in embodied AI, such as grasping, assembly, and folding laundry, are performed on robotic arms; common ones include Franka, UR5e, WidowX, and the low-cost SO-100.

ExampleMost of the data in the Open X-Embodiment dataset comes from single-arm or dual-arm robotic arms.
