In this paper, the well known recursive Newton-Euler
inverse dynamics algorithm for serial manipulators is reformulated into
the context of the algebra of Dual Quaternions. Here we structure
the forward kinematic description with screws and line displacements
rather than the well established Denavit-Hartemberg parameters, thus
accounting better efficiency, compactness and simpler dynamical models.
We also present here the closed solution for the dqRNEA, and to do
so we formalize some of the algebra for dual quaternion-vectors and
dual quaternion-matrices. With a closed formulation of the dqRNEA
we also create a dual quaternion based formulation for the computed
torque control, a feedback linearization method for controlling a serial
manipulator's torques in the joint space. Finally, a cost analysis of the
main Dual Quaternions operations and of the Newton-Euler inverse
dynamics algorithm as a whole is made and compared with other results
in the literature.
