Skeleton of a serial robot arm with six revolute joints. This is one example of a kinematic structure, reducing the motion modelling and specification to a geometric problem of relative motion of reference frames. The Kinematics and Dynamics Library (KDL) develops an application independent framework for modelling and computation of kinematic chains, such as robots, biomechanical human models, computer-animated figures, machine tools, etc. Click below to read the rest of this post.
