Problems solved by technology

[0003] The purpose of the present invention is to solve the disadvantages of the existing force feedback data gloves, such as high price, complex system, and difficult maintenance, and proposes a combination of an external angle sensor and a joint two-way active drive device, which is used to detect the movement information of human hand joints. At the same time, it also converts the feedback force sensory information into a force or torque that directly acts on the human hand, which greatly simplifies the complex force feedback data glove system

Abstract

The human hand far knuckle detection drive mechanism relates to a device that detects the movement state of the human hand far knuckle and has the force feedback from the hand far knuckle joint. The present invention aims to solve the shortcomings of the existing force feedback device, such as the separation of the joint measurement mechanism and the force feedback mechanism, the complex structure of the system, the difficulty in maintenance, the inability to realize two-way active driving, and the high price. The joint detection mechanism and the force feedback mechanism are integrated into the It adopts a unique connection method and ingenious layout of joint measurement points, so that when the operator uses the device, the finger to be detected can maintain maximum flexibility, and the motion state can be accurately detected, so that the controlled slave The far knuckle joints of the hand can act in unison with the corresponding finger far knuckle joints of the operator, and can feed back the force of the hand in a specific working environment to the operator, so as to enhance the sense of presence in virtual reality or teleoperation .

Description

technical field [0001] The invention relates to a device which detects the motion state of the far knuckle of human hand and has the function of two-way feedback force. Background technique [0002] Due to the development of science and technology, robots are gradually being used in an increasing range. As a reliable and mature robot, teleoperation robots are widely used in various dangerous, complex and inaccessible environments. It uses a very reliable control method, which is directly controlled by the operator's instructions. As the tasks performed by teleoperated robots become more and more complex, people put forward higher requirements for their flexibility while pursuing reliability, and it is necessary to implement teleoperation on complex manipulators to control the movement of multiple fingers of the manipulator. Multiple joints move together to achieve specific functions, which requires the use of data gloves, and the data glove with force feedback function is t...
