To solve bionic manipulator space position feedback,electrooculography(EOG) is used as the neurofeedback in the system.The mapping rules between the eye rotation angle and the corresponding EOG are analyzed by the experiment,in which the subjects repeatedly scan the multi-angle targets,and then the location model based on binocular vision of human eye is established;then the targets location information extracted from the parametric location model is converted to the manipulator coordinates via the quaternion coordinate transformation model between human eye and manipulator on the physics experiment platform to guide the positioning.The results show that the location model following binocular vision of human eye enables to effectively extract targets coordinates to provide space position feedback for bionic manipulator;simultaneously it provides a new idea for bionic manipulator space position feedback.
