Robotic Arm

A programmable mechanical device with jointed segments that can grasp, move, and manipulate objects, controlled through various input methods. In assistive technology contexts, robotic arms are used to extend the physical capabilities of people with motor impairments, enabling them to perform daily living tasks such as eating, drinking, picking up objects, opening doors, and operating equipment that they cannot do independently. Assistive robotic arms can be mounted on wheelchairs, tables, or standalone bases, and may be controlled through joysticks, switches, eye tracking, brain-computer interfaces, or voice commands. The number of degrees of freedom (joints that can move independently) determines the arm's flexibility and the range of tasks it can perform.
