Enlist any three characteristics of the following (with respect to robotics):

(a) Linear Motion

(b) Circular Motion

(c) Prismatic Joint

(d) Revolute Joint

(a) Three characteristics of Linear Motion:

1. The movement occurs in a straight line, which can be horizontal, vertical or diagonal.
2. The linear motion is usually controlled by actuators such as motors, hydraulic cylinders or linear actuators, which provide force to move the robot in a designated direction.
3. The linear motion allows for accurate positioning, making it ideal for tasks such as pick-and-place operations, assembly and material handling.

(b) Three characteristics of Circular Motion:

1. The robot moves around a central axis, either internal (like a robot arm rotating at the base) or external (moving around an object or location).
2. Circular motion is controlled by motors and actuators that manage the rotational speed and direction of the robot.
3. In this motion, the robot maintains a constant distance from the center of the path, forming a circular route.

(c) Three characteristics of Prismatic Joint:

1. The prismatic joints move in a straight line (linear motion) along one axis (X, Y or Z), enabling linear extension or compression.
2. It provides a single degree of freedom, allowing movement in one linear direction.
3. The motion is controlled by linear actuators such as hydraulic or pneumatic cylinders or motors, which drive the movement along the designated axis.

(d) Three characteristics of Revolute Joint:

1. Revolute joints allow a robot to rotate a part around a single axis, enabling angular movement, typically measured in degrees.
2. Each revolute joint has one degree of freedom, meaning it provides rotation around only one axis (horizontal or vertical).
3. The rotation is controlled by motors, such as servo or stepper motors, which regulate the angle, speed, and direction of movement.
