Walking chair device controlled by electroencephalogram signals and control system thereof

Abstract

The invention relates to a novel foot type auxiliary movement device using a brain-machine interface and a control system thereof. The system is characterized in that limited kinds of electroencephalogram signals can be used for operation and control; the adaptation to the unflattened terrain environment can be realized; a user can be helped to realize the safe and reliable navigation and movement; the system comprises a walking chair robot and a brain-machine interface. The user is in charge of task statement; the walking chair robot is in charge of task concrete planning and execution; the brain-machine interface solves the decision intention of the user according to the electroencephalogram signals, and is in charge of the communication between the user and the wheelchair robot; the structure of the walking chair robot is divided into an upper part and a lower part in the space; the lower side is a four-foot moving system; the upper side is a rotatable chair platform. The user can perform the practical brain control operation by sitting on the chair platform and can perform remote control operation on the brain control walking chair at the remote end by using the brain-machine interface. In addition, the brain control walking chair also provides a conventional operation rocker rod for a patient with the hand moving ability to use. The control system performs the man-machine cooperated control by using the safety as the first target; the high-grade intention of people is understood through an intension solving module; the intention of people is possibly met on the premise of ensuring the safety.

Description

technical field [0001] The invention relates to a brain-controlled walking chair robot and a control system thereof. More specifically, the present invention relates to a quadruped walking chair robot and a control system for manipulation and navigation using limited types of non-invasive EEG signals. It belongs to the field of intelligent robot technology. Background technique [0002] As one of the auxiliary tools widely used at home and abroad today, electric wheelchairs have brought benefits to paralyzed patients. However, traditional electric wheelchairs use joysticks and buttons for control, so they cannot be applied to patients with limited hand manipulation ability such as muscular dystrophy and bone marrow injury. At present, such patients still need to rely on a lot of manpower and financial resources to take care of their daily life and activities, and the patients are also under psychological pressure. The quality of life of the above-mentioned patients, espec...

Problems solved by technology

However, most of the current interior buildings are not specially designed for the walking needs of wheelchairs at the beginning of the design.

When facing large steps, slopes, and thresholds, without the assistance of outsiders, it is difficult for users to adapt to this type of environment only relying on brain-controlled wheelchairs
