A degree of freedom is a plane of movement. The concept of degrees of freedom is central to kinematics.
Consider a ship moving.It is moving in three dimensions.
- First, up and down in a vertical plane
- Second, left and right in a horizontal plane;
- Third backward and forward, also in a horizontal plane.
Each of these corresponds to one degree of freedom.
Within each of these planes, or axes of movement, an object can rotate thus adding a degree of freedom in each plane and making a total of 3 rotational degrees of freedom.
Human upper limb has been studied in detail and degrees of freedom are important for constructing upper limb prosthetics especially the robotic prosthetics. [Read more...]
