What is a Revolute Joint in Robotics?

In robotics, a revolute joint is a type of joint that allows for rotation around a single axis. It is also known as a prismatic joint or a translational joint.

A revolute joint consists of two parts: a fixed part and a moving part. The fixed part is attached to the robot's frame, while the moving part is connected to a limb or an end effector. The joint allows for rotation of the moving part around the fixed part, which enables the limb or end effector to move in a specific direction.

Revolute joints are commonly used in robotic arms and grippers to enable the arm to move in different directions and to perform tasks such as grasping and manipulating objects. They are also used in other types of robots, such as humanoid robots, where they allow for movement of the limbs and torso.

In summary, a revolute joint is a type of joint that allows for rotation around a single axis, and it is commonly used in robotics to enable movement of limbs and end effectors.
