Abstract

The invention belongs to the technical field of brain-computer interface and robot control, and provides a P300-based brain-controlled robot system and a realization method thereof. The system comprises a visual stimulation module, and a testee, an electrode cap module, a Neuroscan electroencephalogram collection module, a signal processing module, a control interface module, a Pioneer3-DX robot motion module connected with the visual stimulation module in sequence; the Pioneer3-DX robot motion module is further connected with the visual stimulation module; and the control interface is furtherconnected with a Pioneer3-DX robot environment detection module. Graphic symbols are adopted as new stimulation types, and brain-computer interface attributes are combined and improved, so that a higher-amplitude P300 component is induced, and the system transmission rate is increased. Moreover, in combination with a brain-computer interface technology and an automatic control technology, interactive sharing of brain control and robot autonomous control is realized in an asynchronous control mode, and motion behaviors of forward moving, backward moving, left turn, right turn and stillness ofa robot are realized, so that the system is more stable and quicker.

Description

technical field [0001] The invention relates to a P300-based brain-controlled robot system and an implementation method thereof, belonging to the technical field of brain-computer interface and robot control. Background technique [0002] Brain-Computer Interface (BCI) is a non-muscular communication channel established between the brain and external devices, which realizes the communication between the brain's intentions and the external environment. As a new way of human-computer interaction, BCI provides a new idea for the brain control of equipment, has become a research hotspot in the field of intelligent robots, and has built a bridge combining "human brain biological intelligence" and "artificial intelligence". With the integration of BCI technology and robot automatic control technology, a new technology-brain-controlled robot technology has emerged. In the brain control system, according to different application scenarios, the selected BCI control signals are also ...
