4. Prismatic Joint

How many degrees of freedom does the following figure have?

1. two
2. three
3. four
4. six

If a simple robotic arm is having with three revolute joints, then how many degrees of freedom will it have?

1. three
2. four
3. five
4. six

Fill in the blanks:

1. The …………… of Industrial Robots deals with the assembling of various components of a robot.
2. …………… motion refers to the movement of a robot in a plane, allowing it to travel along both the X and Y axes simultaneously.
3. The movement of …………… motion occurs in a straight line, which can be horizontal, vertical or diagonal.
4. …………… links are solid components that do not bend or compress, providing stability and consistency in motion.
5. …………… joint provides a single degree of freedom, allowing movement in one linear direction.
6. Each revolute joint has one degree of freedom, meaning it provides rotation around only …………… axis (horizontal or vertical).
