Jet-HR1: a robot that maintains the balance with the help of propellers
Advanced bipedal robots are already pretty well can maintain balance while walking. But this is true only to a flat surface. If there are irregularities bipedal robots begin to stumble and fall, and even the most advanced stabilization system can not prevent them from doing so. But researchers from the University of Technology, Guangdong (China) found a very elegant solution to the above problem. They decided to use the propellers on the robot legs that help you keep your balance even in the most difficult conditions.
Robot with propellers called Jet-HR1, and the main function of the rotors, the assurance of developers, is partial compensation of the center of gravity that allows the robot to perform a fairly wide steps with no chance to fall on its side. Jet-HR1 robot has a height of 65 centimeters, and the weight 6, 5 kilograms, each propeller is able to lift the weight to 2 kilograms, which together with the stabilization system gives very good results.
In a series of experiments stepped robot over the obstacle 37 centimeters in width, which is 80 percent of the maximum possible length of the pitch of the robot. When walking each propeller accelerates to maximum speed, keeping his leg in an upright position and preventing the robot mislaid. The fan on the "back" leg, which remains behind while walking, rotates in the opposite direction, Jet-HR1 pressed to the ground and thus providing additional stability. After the robot puts "front" foot on surface, propellers change the direction of rotation so that the "front" foot attracted, and "rear" repellent. After this cycle is repeated. The very process of movement you can see in the video, available below.
