Hand/thumb joint linkage unit

Abstract

The invention discloses a hand / thumb joint linkage unit which is mainly provided with a palm body, a plurality of finger modules and a thumb module, wherein the thumb module and the finger modules are arranged on the palm body; a plurality of knuckles capable of doing joint movement are arranged; the knuckles are mutually connected by connecting rods; and a single actuator can simultaneously drive all the knuckles to move, therefore, a manipulator can do multi-joint and multi-degree-of-freedom gesture movement.

Description

technical field [0001] The invention relates to a mechanical arm, in particular to a hand / thumb joint linkage unit which can drive the joints of the hand / thumb to make different gestures by using a single actuator. Background technique [0002] With the progress of the times, the research and development and application of robots have gradually shifted from industrial robots that support industrial purposes to robots that are used in people's livelihood, medical care, entertainment and other service purposes. Robots for tour guide services are used in various public relations occasions, museums or Art museums and other places are used to attract the attention of the public with its novel technology, and then lead the audience and convey various messages. Business opportunities are expected. However, as far as the robots used for tour guide services are concerned, most of them can only do a few simple ones.

[0002] With the progress of the times, the research and development and application of robots have gradually shifted from industrial robots that support industrial purposes to robots that are used in people's livelihood, medical care, entertainment and other service purposes. Robots for tour guide services are used in various public relations occasions, museums or Art museums and other places are used to attract the attention of the public with its novel technology, and then lead the audience and convey various messages. Business opportunities are expected. However, as far as the robots used for tour guide services are concerned, most of them can only do a few simple ones. Greeting gestures are rarely able to present complex movements similar to human gestures, so there is still room for technical improvement at the level of interaction. Compared with high-end manipulators that can perform various fine movements, although they can show complex gesture shapes, they are suitable for use in The use of navigation robots, but relative to the joint movements of its parts, because it needs to use a large number of actuators as control, the manufacturing cost is relatively high, and the volume is relatively large, which is not conducive to industrial utilization
