Title: DRIVING ARM WITH MULTIPLE DEGREES OF FREEDOM AND TWIN-ARMED ROBOT USING SAME
Abstract:
Disclosed is a driving arm with multiple degrees of freedom, the driving arm comprising a driving module (1) with a single degree of freedom and several driving modules (2) with dual degrees of freedom, wherein the driving module (1) with a single degree of freedom is connected to the driving modules (2) with dual degrees of freedom located at the innermost side; the driving modules (2) with dual degrees of freedom have two orthogonal rotational degrees of freedom, the first rotational degree of freedom comprising a first driving mechanism used for driving the rotation of the driving module (2), and the second rotational degree of freedom comprising a second driving mechanism for driving the rotation of the driving module (2); the first driving mechanism, of the driving module (2) with dual degrees of freedom which is located at the outside, is provided on the second driving mechanism, of the driving module (2) with dual degrees of freedom which is adjacent thereto and located inside. Also included is a twin-armed robot using the driving arm with multiple degrees of freedom. A single arm of the robot has seven degrees of freedom, the robot has variable flexibility, and is suitable for accomplishing various complex tasks; the cost thereof is low, the structure is compact, the energy density in unit volume of its own structure is maximised; and the arm uses a modularised structure, ensuring good replaceability and saving on servicing and maintenance costs.
