Embodiment Construction

[0033] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that all the drawings of the present invention are in simplified form and use inaccurate scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0034] Realize the present invention needs to design and manufacture five-finger finger and driving mechanism and palm structure, the present invention provides a kind of anthropomorphic all-driven five-finger dexterous manipulator for this reason, as figure 1 As shown, it includes palm assembly 6, thumb assembly 5, index finger assembly 4, middle finger assembly 3, little finger assembly 2 and ring finger assembly 1, simulating human palm and five finger structures. The four fingers other than the thum...

Abstract

The invention provides a personate full-driving five-finger smart mechanical hand which comprises a palm assembly, four sets of common finger assemblies and one set of thumb assembly. The common finger assemblies can simulate the three-freedom-degree bending movement and lateral opening and closing movement of the fingers of human, and the thumb assembly can be used for achieving two-freedom-degree independent rotation movement and two-freedom-degree coupling rotation movement. The personate full-driving five-finger smart mechanical hand has the following beneficial effects that firstly, smartness is high, 20 freedom degrees are achieved, and independent control is achieved; secondly, the mechanical hand is small in size and is similar to the common adult hand in size and is smaller than the size of 200 mm*95 mm*35 mm; thirdly, the weight is small and is smaller than 500 g; and fourthly, the mechanical hand can be locked by itself after being powered off.

Description

technical field [0001] The invention relates to a manipulator, in particular to an anthropomorphic full-drive five-finger dexterous manipulator, which belongs to the technical field of robots. Background technique [0002] In recent years, the application of robot technology in both industrial and civil fields has developed rapidly. The manipulator is the final actuator of the robot's work, and its performance directly determines the working ability of the robot. Similar to humans, the development of manipulators with high versatility and dexterity is necessary. [0003] At present, domestic institutions including Beihang University, Tsinghua University, Harbin Institute of Technology and the Institute of Automation of the Chinese Academy of Sciences have some technical research on dexterous manipulators. However, its volume is large, its weight is high, it is not fully driven by five fingers, and its dexterity is insufficient. In foreign countries, although manipulators ...
