Technical details and manufacturing context for Wrist Assembly

Definition
The wrist assembly is a critical component of a robotic arm system that connects the forearm to the end-effector. It typically consists of multiple joints and actuators that allow for pitch, yaw, and roll movements, providing the dexterity needed for complex manipulation tasks in industrial automation, assembly, welding, and material handling applications.
Working Principle
The wrist assembly operates through a combination of mechanical joints (such as revolute or spherical joints) driven by electric motors, hydraulic actuators, or pneumatic systems. Control signals from the robot's controller precisely coordinate the movement of each joint to achieve the desired orientation of the end-effector in three-dimensional space.
