Abstract

The present invention provides a method for controlling a manipulator based on the MI‑SSVEP hybrid brain-computer interface, through non-invasive EEG data collection, EEG signal online preprocessing, EEG signal online processing and decoding, generating user intention targets and Transform the target into steps such as control instructions to realize the control of the robotic arm. Based on the MI-SSVEP hybrid brain-computer interface experimental paradigm, it increases the number of degrees of freedom for the brain-computer interface to control the manipulator system, realizes the movement control of the manipulator in three-dimensional space, enhances the flexibility of user control, and establishes A new mapping relationship between the decoding result of the brain-computer interface signal and the user's intention is more in line with the intuition of the user's control, and improves the efficiency of the user's intention to control the robotic arm.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a method for controlling a robotic arm based on an MI-SSVEP hybrid brain-computer interface. Background technique [0002] At present, the number of people with disabilities is on the rise. Among the large number of disabled people, the number of people with physical disabilities occupies a large proportion. This group poses challenges to health care and social security systems, places enormous economic pressure on families and society, and urgently needs to improve and improve the quality of life of persons with disabilities. Brain Computer Interfaces (BCI) is a new technology aimed at establishing a new pathway between the brain and the outside world. Through brain-computer interface technology, disabled patients can directly communicate and communicate with the outside world through "ideas", bypassing traditional neural pathways. The combination of brain-computer interface ...
