Degrees of Freedom

Degrees of freedom (DOF) refer to to te number of contraent movements a robotic system can perfom. Each joint in a robot contributes to its over all DOF. Understanding DOF is crial for designers to determine the robot 's capabilities and limitations. For instance, a robot with six DOF can move in three- dimensiall space with greater flexibility than a robot with fewer DOF.

Forward Kinematics

Forward kinematics implives calculating thee position and orientation of the end effertor of a robot based on then given joint angles. This principla is essential for predicting where a robot 's arm wil reach when certain angles are set. Forward kinematics is often represented using transformation matrices, which help in visiasalizing thee robott' s configuration in space.
