Bionic hand system and control method

Abstract

The invention belongs to the technical field of manipulators, and relates to a bionic hand system and a control method. A bionic hand system comprises a master control end, a rigid-flexible bionic hand and a slave control end. The master control end comprises a data glove, a portable computer and near-end ad hoc network equipment; the slave control end comprises an air pump, a positive and negative pressure control box and far-end ad hoc network equipment; the data glove is used for collecting bending data of each joint of a human hand in real time and transmitting the bending data to the portable computer, then a control instruction is transmitted to the far-end ad-hoc network device through the near-end ad-hoc network device, the air pump is connected with the positive and negative pressure control box, and the positive and negative pressure control box receives information of the far-end ad-hoc network device and sends the information to the portable computer. And the air pump is controlled to inflate or exhaust air to the rigid-flexible bionic hand, so that the rigid-flexible bionic hand is controlled. According to the invention, the bionic hand can be remotely operated and controlled to replace a human hand to complete a complex task in an unstructured dangerous environment so as to guarantee the safety of a worker, and meanwhile, the action precision and response speed of the pneumatically driven bionic hand are improved.

Description

technical field [0001] The invention belongs to the technical field of manipulators, and relates to a bionic hand system and a control method. Background technique [0002] With the rapid development of science and technology, bionic manipulators continue to emerge, which can achieve various dexterous actions by controlling bionic hands to complete complex operational tasks. Among the existing manipulator drive methods, the actuator performance of the pneumatic bionic manipulator is excellent, and the pneumatic system has low requirements on the external environment, which can meet the operation requirements in an unstructured environment. However, the control accuracy of the pneumatically driven bionic hand is low, and when the air pressure is removed, the response speed is slow, and the bionic hand cannot make the next dexterous movement in time, which greatly affects the efficiency and performance of the bionic hand. At the same time, the existing mechanical control lack...

However, the control accuracy of the pneumatically driven bionic hand is low, and when the air pressure is removed, the response speed is slow, and the bionic hand cannot make the next dexterous movement in time, which greatly affects the efficiency and performance of the bionic hand

At the same time, the existing mechanical control lacks the remote operation control function, and the teleoperation system can enable the staff to remotely operate the bionic hand to perform complex tasks in a safe place
