Multi-jointed arm

Definition

A multi-jointed arm refers to a robotic limb designed with multiple degrees of freedom, allowing it to mimic the complex movements of a human arm. This type of arm is particularly important for prosthetic limb control, as it enables users to perform intricate tasks that require precision and coordination, similar to natural arm movement. The design often includes various joints that can rotate and bend, providing a range of motion that enhances functionality and usability for individuals using prosthetics.
