Four-foot-swing wall-climbing robot with driven waist joint

The invention discloses a four-foot-swing wall-climbing robot with a driven waist joint. The wall-climbing robot comprises four telescopic foot modules, an upper body part, a lower body part and a tail module; the telescopic foot modules are active motion modules and each composed of a steering engine and a transmission mechanism, each transmission mechanism is formed by bevel gears and a crank slide bar mechanism to transmit power of the corresponding steering engine, and then four telescopic legs can do linearly telescopic motion. The four telescopic foot modules are connected with the left side and the right side of the upper body part and the left side and the right side of the lower body part respectively. The upper body part and the lower body part are internally provided with cavities used for installing a control panel and a battery and are connected through the waist joint. The waist joint does passive motion, and the robot can climb a wall or walk through active motion of telescopic feet of skew symmetry. The wall-climbing robot has the advantages that the overall structure is compact and flat and high in stability; the ratio of the upper body to the lower body can be adjusted according to optimization needs; changes of mass center motion tracks and foot end force of climbing animals can be fitted, and the motion speed of the four-foot-swing wall-climbing robot with the driven waist joint is effectively increased.

Fall-down detection alarm system based on Kalman filtering and KNN algorithm and method thereof

The invention discloses a fall-down detection alarm system based on Kalman filtering and a KNN algorithm and a method thereof. The system comprises an acquisition module, a processing module, a transmission module, an identification module, a judgment module and a notification module. The acquisition module is used for acquiring three-dimensional acceleration and three-dimensional angular velocity data of the upper body part in movement of a human body. The processing module calculates resultant acceleration and resultant angular velocity through the three-dimensional acceleration and three-dimensional angular velocity data. The identification module performs classified identification on the movement state of the human body based on Kalman filtering and the KNN algorithm so as to identify the movement type of the human body. The judgment module judges whether the movement type of the human body is a "fall-down" type, and the notification module notifies the set contact persons through the set alarm manner if the judgment result is the "fall-down" type. The movement state of the human body is identified based on Kalman filtering and the KNN algorithm so that detection accuracy is high and false alarm rate is low; and the system has a communication function and can notify the relatives of the fall-down elder in real time and determine the fall-down position.
