Technical details and manufacturing context for Joints with Actuators

Definition
Joints with actuators are critical components of robotic manipulators that combine mechanical articulation points with power sources (actuators) to create controlled motion. These assemblies enable the robotic arm to achieve precise positioning, orientation, and movement through various degrees of freedom. They serve as the fundamental building blocks that transform electrical or hydraulic energy into mechanical motion at specific articulation points along the manipulator structure.
Working Principle
Actuators (electric motors, hydraulic cylinders, or pneumatic systems) generate force/torque that is transmitted through mechanical linkages to rotate or translate the joint. Control systems regulate actuator output based on position, velocity, or torque feedback to achieve precise movement according to programmed trajectories.
Common Materials
Aluminum alloy, Steel, Composite materials
