In mechanical engineering, the Denavit–Hartenberg parameters (also called DH parameters) are the four parameters associated with a particular convention for attaching reference frames to the links of a spatial kinematic chain, or robot manipulator. Jacques Denavit and Richard Hartenberg introduced … See more A commonly used convention for selecting frames of reference in robotics applications is the Denavit and Hartenberg (D–H) convention which was introduced by Jacques Denavit and Richard S. Hartenberg. In this … See more The Denavit and Hartenberg notation gives a standard (distal) methodology to write the kinematic equations of a manipulator. This is … See more For the dynamics three further matrices are necessary to describe the inertia $${\displaystyle J}$$, the linear and angular momentum $${\displaystyle \Gamma }$$, … See more • Forward kinematics • Inverse kinematics • Kinematic chain • Kinematics See more It is common to separate a screw displacement into product of a pure translation along a line and a pure rotation about the line, so that See more Further matrices can be defined to represent velocity and acceleration of bodies.
