DRIVING ARM WITH MULTIPLE DEGREES OF FREEDOM AND TWIN-ARMED ROBOT USING SAME

摘要

The present disclosure discloses a multi-degree-of-freedom driving arm and a dual-arm robot using the arm, the multi-degree-of-freedom driving arm comprises a single-degree-of-freedom driving module and a plurality of dual-degree-of-freedom driving modules, and the single-degree-of-freedom driving module and the dual-degree-of-freedom driving module located at the innermost side are coupled to each other; the dual-degree-of-freedom driving module has two orthogonal rotational degrees of freedom, and comprises a first driving mechanism that is configured to drive the dual-degree-of-freedom driving module to rotate in the first rotational degree of freedom, and a second driving mechanism that is configured to drive the dual-degree-of-freedom driving module to rotate in the second rotational degree of freedom; the first driving mechanism of the dual-degree-of-freedom driving module located on outer side is disposed on the second driving mechanism of the dual-degree-of-freedom driving module adjacent thereto and located on inner side. The robot has seven degrees of freedom for each arm, so that it is flexible and suitable for performing various complicated tasks; the robot has low cost and compact structure, and the energy density of the self-structure per unit volume is maximized; the arm has a modular structure that ensures excellent interchangeability and saves on maintenance costs.
