A robot constructs a navigation map based on the cognitive mechanism of rat hippocampus. The robot collects current self-motion cues and color depth map information through exploring the environment; self-motion cues form spatial environment codes gradually through path integral and feature extraction of spatial cells in hippocampus, place field of place cells is gradually formed during exploring the process and covers the whole environment to form a cognitive map. Further, Kinect collects scene view and color depth map information of the current position in right ahead direction as an absolute reference, proceeding path closed-loop detection to correct the errors of the path integral. At a close-loop point, the system proceeds reset of spatial cells discharging activity to correct the errors of the path integral. The final point in navigation map includes coding information of place cells series, corresponding visual cues and position topological relationship.

A method and device of torque generation based on electromagnetic effect is provided. An electromagnetic torque whose direction is opposite to the motor driving direction is generated in a magnetic field when a motor-drive armature winding is adopted based on the electro-magnetic induction principle. Meanwhile, a reverse electromagnetic torque which is reverse to the armature winding with the same magnitude, is applied on a magnet set and is transmitted to an underactuated system so as to provide required torque for the underactuated system. Advantageously, the provided torque is in direct ratio to speed, difficulty in control is significantly reduced, two-stage electromagnetic variable speed can be achieved, the design of the system is simple and reliable with a concise and clear structure, and the device may be employed in a wide variety of applications.

This invention relates to a single wheel robot system and its control method. The robot is an intelligent self-control and thus self-balancing unicycle riding robot. The control method is the balance control method of the static imbalance unicycle robot. The single wheel robot includes mechanical body and control system; the body contains a single wheel in the substructure which can rotate around for balance; the control system comprises state sensors, motion controller, servo-driven controllers, and a power system. Among them, the motion controller receive signals from the state sensors, in accordance with control procedures for processing of the received signal, thereby issuing control instructions. The servo drive controller receives the control instructions and controls the motors of the robot to adjust posture to be balanced.
