Embodiment Construction

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as Figure 1 to Figure 5 As shown, the embodiment of the present invention discloses a robotic hand, which is used for grasping objects 100 such as balls, blocks, and strips. The robotic hand includes a root finger 10, a belly finger 20, a pointed finger 30, a power mechanism and a differential mechanism. The root finger 10 is connected to the fixed device or the mobile device; the abdomen finger 20 is rotatably connected to the root finger 10, and the pointed finger 30 is rotatably connected to the abdomen finger 20; the differential mechanism and the motive mechanism, the abdomen finger 20 and the root Refers to 10 direct or indirect connections. The key of the present invention is: the power mechanism distributes...

Abstract

The invention discloses a manipulator which comprises a finger root, a finger pulp, a finger tip and a power mechanism, and further comprises a differential mechanism, wherein the finger pulp is rotatably connected onto the finger root; the power mechanism is rotatably connected onto the finger pulp; the differential mechanism is connected with the power mechanism, so that when the rotation of thefinger pulp is limited by a grabbing object, the finger tip is driven by the power mechanism to rotate relative to the finger pulp and towards the grabbing object; and when the finger pulp is not limited by the grabbing object, the finger pulp is driven by the power mechanism to rotate. The manipulator disclosed by the invention has the advantages that by utilization of the differential mechanism, the differential effect is generated between the finger pulp and the finger tip, so that the action of a real hand to grab an object can be better simulated; during the grabbing action, such a grabbing way that a finger pulp and a finger tip of a conventional manipulator simultaneously rotate towards the grabbing object is adopted; and accordingly, compared with the conventional manipulator, themanipulator disclosed by the invention further fits human engineering.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a robot hand. Background technique [0002] The robotic dexterous hand is the multi-degree-of-freedom end effector of the robot arm, and it is also a key component for the robot arm to achieve various functional operations. There are usually several considerations when designing and manufacturing robotic dexterous hands: [0003] Weight: The smaller the self-weight of the dexterous hand, the larger the load can be grasped at the end of the same mechanical arm; [0004] Simplified structure: The simpler the structure, the more reliable the work, the lower the failure rate, and the lower the manufacturing cost; [0005] Drive unit: meet design requirements with as few drive units as possible, because drive units (such as motors, etc.) usually occupy most of the cost of dexterous hands. [0006] The robotic hand in the prior art includes a root finger, an abdomen finger rotatably ...
