Explanation:-- It has one linear and two rotary motions. It consist sliding arm actuated relative to the body, which can rotate about both vertical axis and horizontal axis.


Spherical robot is a stationary robot with two rotary joints and one prismatic /linear joint which forms a spherical coordinate system and hence it called spherical robot.


Its degree of freedom is ‘3’

It is as follows

This robot positions the wrist through two rotations and one linear actuation.

As shown in the orientation the tool plate is achieved through three rotations in the wrist

with roll of A, Pitch of B and Yaw of C.


OR


Degrees of freedom (DOF) can be defined as a term that describes a robot’s freedom of motion in three dimensional space. It refers to the ability of the robot arm to move forward and backward, up and down, and to the left and to the right.
