In the robotics field, one important aspect is the control of serial link manipulators or robotic arms, respectively. A serial link manipulator is a series of links connected with actuated joints, commonly with an end-effector attached to the last link. One of the most famous robotic arms is the Unimate Puma560, that is shown in the figure on the right.
Each manipulator has a certain amount of joints, that can be controlled. The Puma560 for example has three revolute joints (see figure). The spacial relationship between the links depends on the current joint parameters and so does the transformation of the end-effector with respect to the manipulators base frame. This transformation is of high importance for the control of a robotic arm as objects are to be grabbed at certain positions and for example kinematics is highly dependent on it.
In the following subarticles all important aspects of the Denavit-Hartenberg convention are treated in detail:
