How many degrees of freedom does the following figure have?

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

Which of the following is not related to degree of freedom that provide the ability to robots to rotate and change orientation freely?

1. pitch
2. yaw
3. roll
4. swing

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).

State whether the following statements are True or False:

1. Revolute joints allow a robot to rotate a part around a single axis, enabling angular movement, typically measured in degrees.
2. Soft links maintain the overall shape and strength of the robot, which is crucial for supporting weight and handling various tasks.
3. The angular motion systems often incorporate guide rails to ensure smooth, straight movement and prevent lateral deviations.
4. Circular motion refers to as the movement of a robot along a curved or circular path around a fixed point or axis.
5. Spherical joint allows the links of a robot to move linearly along an axis without rotating.
6. The DoF of a joint indicates the number of independent axes along which motion is allowed.
