Title:
MECHANICAL ARM AND ROBOT
Document Type and Number:
WIPO Patent Application WO/2023/207344
Kind Code:
A1
Abstract:
A mechanical arm, comprising: a first mechanical joint (10), a second mechanical joint (20), and a driving assembly (30). The first mechanical joint (10) comprises a first fixed member (101) and a first movable member (102) which are rotatably connected. The second mechanical joint (20) comprises a second fixed member (201) and a second movable member (202) which are rotatably connected. In a first working mode, at least two driving sources (301) can drive the second movable member (202) to rotate relative to the second fixed member (201), such that the first movable member (102) is fixed relative to the position of the first fixed member (101); in a second working mode, the driving sources (301) drive the second movable member (202), the second fixed member (201), and the first movable member (102) to rotate relative to the first fixed member (101), such that the second movable member (202) is fixed relative to the position of the second fixed member (201). The mechanical arm can realize coupling driving of the at least two driving sources (301) to a plurality of joints, thereby improving the utilization rate of the driving sources (301). The present invention further relates to a robot comprising the mechanical arm.
