Embodiment Construction
[0006] Such as figure 1 and figure 2 As shown, the linear bearing type metacarpophalangeal joint motion detection device includes a potentiometer base 1 , a left bearing cap 2 , a right bearing cap 3 , a linear bearing 4 , a long shaft 5 , a potentiometer 6 , and a ball joint 7 . The shaft of the first potentiometer 6 is fixed to the bottom of the potentiometer base 1 by screws, and the hole seat on the vertical surface of the potentiometer base 1 is connected to the second potentiometer 6 by screws. The shaft of the potentiometer 6 is fixed to the left bearing cover 2 by screws, the linear bearing 4 is fixed by the left bearing cover 2 and the right bearing cover 3 by screws, the long axis 5 is inserted into the linear bearing 4, and the long axis 5 It is slidingly connected with the linear bearing 4, and one end of the long axis 5 is fixedly connected with the ball stud 7. Action implementation process: the linear bearing type metacarpophalangeal joint motion detection de...

The invention provides a linear bearing type metacarpophalangeal joint movement detection device, and relates to a data glove used for detecting the finger movement states of human hands. The device which is attached to the outer portion of a human hand and used for detecting the joint movement is designed to overcome the defects that an existing data glove sensor is high in price, complex in system, difficult to maintain and the like. By means of the unique connection mode and the ingenious joint measurement point arrangement, obstructions or influences caused by a detection mechanism to the finger movement of an operator are reduced or eliminated, flexibility and lightness of the movement of fingers can be kept to the maximum extent when the operator uses the device, all the movement states of joints can be accurately detected, and therefore the finger joints of a controlled slave hand and the corresponding finger joints of the operator can be controlled to act coordinately and constantly, and the complex control over the multi-freedom-degree slave hand is made visible, simple and convenient.
Description
technical field [0001] The invention relates to a data glove for detecting the movement angle and state of human finger joints. 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 in coordination to achieve specific functions, which requires the use of data gloves. Data gloves are the most effective device for teleoperating the robot's manipulator. I...
