Title:
CLOSED-CHAIN ROBOT DYNAMICS MODELING AND SOLUTION METHOD BASED ON AXIS INVARIANT
Document Type and Number:
WIPO Patent Application WO/2020/034399
Kind Code:
A1
Abstract:
A closed-chain robot dynamics and calculation method based on an axis invariant, wherein a Ju-Kane dynamics equation of a closed-chain rigid-body system is established, and the Ju-Kane closed-chain rigid-body dynamics based on a natural axis chain of a joint space overcomes the limitations of a Cartesian coordinate axis chain space: in Newton-Euler dynamics based on a Cartesian coordinate axis chain, a non-tree kinematic pair constraint cannot express constraints, such as a rack and a gear, and a worm gear and a worm. An algebraic constraint equation of the non-tree constraint pair can express any constraint class, and the physical connotation is clear; the complexity of solving a system equation is reduced; and the accuracy of the constraint equation is ensured.
