A concept for manipulator trajectory planning

Pfeiffer, F., Johanni, R.·1987·IEEE Journal on Robotics and Automation

Abstract

A way to find the optimal trajectory of an arbitrary manipulator following a prescribed path is described. The method takes advantage of the fact that in this case overall motion takes place with one degree of freedom (DOF) only. Transforming the equations of motion to this one DOF results in a set of equations which defines the phase space of admissible motion constrained by path geometry and joint torques in a transparent way. The time optimal solution representing the maximum mobility of the path-manipulator configuration can be easily determined by a field of extremals bound by a maximum velocity curve, which acts as a trajectory source or sink. Its properties lead to an algorithm for evaluating the time-minimum curve from a sequence of accelerating/ decelerating extremals. Additional optimizing criteria are studied by applying Bellman's principle.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
