A Chinese painting robot hand and its drawing method based on visually induced brain-computer interface

Abstract

The invention discloses a traditional Chinese painting mechanical hand based on a visual evoking brain-machine interface, and the mechanical hand comprises a visual stimulator main control module, a visual stimulator panel module, an electroencephalogram signal collection module, an electroencephalogram data transmission module, a signal processing module, and a traditional Chinese painting mechanical arm module which employs an AVR programming mechanical hand driven by six servo motors, employs an Atmega168 single-chip computer controller to control the movement of the mechanical hand and achieves the real-time communication with the FPGA in a serial port mode. An electroencephalogram signal collection end in the mechanical hand employs a portable Bluetooth signal for transmission, thereby greatly improving the flexibility of data transmission and network transmission speed, improving the practicality of the brain-machine interface, and improves the cultural connotation while improving the control precision. Finally, a miniaturization path has to be achieves through an embedded mode of a brain-machine interface system, and a portable brain-machine interface system is good in application prospect. The invention also discloses a drawing method for the traditional Chinese painting mechanical hand based on the visual evoking brain-machine interface.

Description

technical field [0001] The invention relates to the technical field of embedded signal processing, in particular to a Chinese painting robotic hand based on a visually induced brain-computer interface. The invention also relates to a drawing method of a Chinese painting robotic hand based on a visually induced brain-computer interface. Background technique [0002] As the nervous system control center that coordinates physical and mental activities, the human brain manages various nervous systems that communicate between the human body and the outside world. In today's world, more and more people are troubled by cerebral apoplexy, various paralysis, aphasia, and Pep syndrome. The continuous improvement of medical level is conducive to prolonging the life cycle of these patients. However, due to the lack of control over muscles, They cannot communicate and control effectively with the outside world, and the quality of life cannot be guaranteed, which brings a heavy burden to...

Problems solved by technology

At present, the brain-computer interface system is basically realized based on the PC. In order to improve the practicability of the brain-computer interface system, the brain-computer interface system must develop in the direction of miniaturization, but the current domestic brain-computer interface system is large Most of them are implemented based on PC, the system is bulky and not very practical
