Embodiment Construction

[0028] Specific embodiments are given below in conjunction with the accompanying drawings to further illustrate how the service robot system based on the brain-computer interface of the present invention is realized.

[0029] The development platform of the service robot system based on the brain-computer interface of the present invention adopts the remote brain control mode. The principle is that the human brain emits brain waves, and the brain wave signals after the eyes are closed for a short time are collected through the scalp lead electrodes, and then enter the computer through the signal acquisition card after pre-amplification; the signal processing module in the computer performs feature recognition, Judge the subject’s eye-opening and closing state, and then send out the corresponding control signal; the state selector receives the signal processed by the computer, and locks a direction information; the control interface receives the direction selection signal provid...

Abstract

The invention discloses a service robot system based on a brain-computer interface, which comprises a scalp electrode connected with the human cerebrum, an EEG amplification unit, an EEG acquisition unit, a computer, a state selector and a control interface, wherein the EEG amplification unit is used for receiving and amplifying a signal of the scalp electrode; the EEG acquisition unit acquires the amplified EEG signal and performs A / D conversion on the amplified EEG signal; the computer processes the EEG signal; the state selector receives the signal processed by the computer and locks direction information; the control interface receives a direction selection signal provided by the state selector and sends the signal to a serial port of the computer, and the computer wirelessly transmits the signal to a service robot; and the human cerebrum respectively receives feedback signals of the state selector and the service robot through the sight. According to a general characteristic that the amplitude of alpha wave in EEG can be obviously increased after 90 percent people with normal brain-neural function close eyes in a short time, the service robot system realizes that the alpha wave in EEG controls the movement of the service robot in four directions, and can quickly and reliably control external service robots without training.

Description

technical field [0001] The invention relates to a service robot, in particular to a service robot system based on a brain-computer interface that can realize brain-electrical alpha waves to control the service robot in four directions. Background technique [0002] Service Robot (Service Robot) is a young member of the robot family. Different countries have different understandings of service robots. So far, there is no unified and strict definition. The International Federation of Robotics (IFR) gives a preliminary definition of a service robot: a service robot is a semi-autonomous or fully autonomous robot that can perform services and work that are beneficial to human health but does not include equipment engaged in production. my country's definition of service robots (also known as Advanced Robots) is: various robots other than industrial robots, mainly used in the tertiary industry, including home robots (Home Robot) and field robots (Field Robot). Service robots are ...
