What is DOF in robotic arm?
A ‘Degree of Freedom’ (DoF) as it relates to robotic arms, is an independent joint that can provide freedom of movement of the manipulator, either in a rotational or translational (linear) sense. For every geometric axis that a joint can rotate around or extend along, this is counted as a Single Degree of Freedom.
What is forward kinematics and inverse kinematics in robotics?
Forward kinematics refers to the use of the kinematic equations of a robot to compute the position of the end-effector from specified values for the joint parameters. The reverse process that computes the joint parameters that achieve a specified position of the end-effector is known as inverse kinematics.
What are the types of robot kinematics?
There are two broad classes of robots and associated kinematics equations: serial manipulators and parallel manipulators. Other types of systems with specialized kinematics equations are air, land, and submersible mobile robots, hyper-redundant, or snake, robots and humanoid robots.
What is a 4 DOF robotic arm?
The 4-DOF robot arm has four joints to imitate a human upper arm namely joint 1, 2, 3 and 4 that rotate around x, y, and z axes, respectively. The joints move four arm links to get the required posture of the wrist that will be assembled with the hand in future application.

How many inverse kinematic solutions are there?
Inverse kinematic equations give the values of joint positions (usually angles) as a function of the desired position and orientation of the hand. For 6 jointed (6 DOF) arms there is a set of 2, 4, or 8 solutions (depending on the arm design) UNLESS the desired pose is unreachable (for example too far away).
Why DOF is important in robotics?
For lower-axis robots (with 6-DOF or less) it’s usually possible to find a closed-form solution for how the joints must move to place the end effector. It is incredibly important for high-DOF robots to be able to deal meaningfully with kinematic redundancy. Humans are experts at this.
