Abstract

The invention discloses a brain-controlled robot system based on a multivariate synchronous exponential algorithm. The invention belongs to the field of brain control. The system comprises an electroencephalogram acquisition module, an online algorithm module, an interactive application module and a feedback module, wherein the online algorithm module comprises a signal calculation module, a calculation platform and a signal frequency identification module; wherein the interactive application module comprises a robot, a circulating receiving module and an interface building module for real-time and ordered instruction transmission. Sine coding stimulation is adopted in the design of a stimulation interface, and stable stimulation can be generated, so that a high-quality steady-state visual evoked potential is induced; an online algorithm adopts a multivariate synchronization index algorithm without training, and results can be classified in real time; an interface between the Matlab and the NAO robot is established by adopting a TCP / IP, and has the advantages of high real-time performance, order arrival of instructions and the like; and finally, all the adopted devices are wireless devices, so that the device is convenient to carry.

Description

technical field [0001] The invention relates to the technical field of brain control, in particular to a brain-controlled robot system based on a multivariate synchronization index algorithm. Background technique [0002] The brain-computer interface is a direct communication and control channel established between the human brain and computers or other electronic devices. Through this channel, people can express ideas or manipulate devices directly through the brain without language or actions. This can effectively enhance the ability of patients with severe physical disabilities to communicate with the outside world or control the external environment, so as to improve the quality of life of patients. With the development of artificial intelligence, brain-computer interface technology has gradually entered people's field of vision, such as brain-controlled wheelchairs, brain-controlled typing, and brain-controlled robotic arms. [0003] The current brain-computer interact...
