Thumb far-end joint detection device for data glove

Abstract

The invention discloses a thumb far-end joint detection device for a data glove and relates to a device for detecting the movement state of fingers of a hand and feeding back the force borne by corresponding finger joints of the hand. By the adoption of the thumb far-end joint detection device for the data glove, the defects that according to an existing force feedback device, a joint measurement mechanism and a force feedback mechanism are separated, a system is complicated, the structure is complicated, maintenance is difficult, bidirectional active driving cannot be achieved, and the price is high are overcome. A joint detection mechanism and a force feedback mechanism are integrated, and a unique connection way and ingenious joint measurement point arrangement are adopted, so that when an operator uses the device, the detected finger can be kept flexible to the maximum extent; the movement state can be accurately detected so that the corresponding finger joint of the controlled hand and the corresponding finger joint of the operator can move cooperatively and consistently, the stress condition of the hand in the specific working environment can be fed back to the operator, and accordingly virtual reality or the sense of immediacy of remote control is enhanced.

Description

technical field [0001] The invention relates to a data glove which detects the movement state of human fingers 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 the most ef...

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 potentiometer and a joint bidirectional active drive device, which can detect the motion 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
