Bartender by night, maker and tinkerer by day, Keahi Seymour has invented a transport design that uses the energy created by running naturally and amplifies his run speed up to 25 mph. The spring-loaded boots, made of speargun springs, carbon fiber and metal isn’t a vision of the future, it is the future.
MIT researchers have developed an algorithm for bounding that they’ve successfully implemented in a robotic cheetah.
The key to the bounding algorithm is in programming each of the robot’s legs to exert a certain amount of force in the split second during which it hits the ground, in order to maintain a given speed: In general, the faster the desired speed, the more force must be applied to propel the robot forward. In experiments the robot sprinted up to 10 mph and MIT researchers estimate the robot may eventually reach speeds of up to 30 mph.
The MIT Cheetah 2 contains the custom electric motor designed by Jeffrey Lang, the Vitesse Professor of Electrical Engineering at MIT and the amplifier designed by David Otten, a principal research engineer in MIT’s Research Laboratory of Electronics.
WildCat is a four-legged robot being developed to run fast on all types of terrain. So far WildCat has run at about 16 mph on flat terrain using bounding and galloping gaits. The video shows WildCat’s best performance so far. WildCat is being developed by Boston Dynamics with funding from DARPA’s M3 program.
From Edison films catalog: This picture was taken from the stationary platform, showing the rapidly moving board walk on the outer edge, which has a speed of five miles per hour; also shows the middle platform moving two and a-half miles per hour, the third platform being stationary. At intervals there are upright posts to steady passengers passing from one platform to the other. By watching these uprights passing by the camera and passing each other, a good idea of the speed is obtained. The structure is crowded with passengers, some gliding by, standing still, other walking and running and stepping from one platform to the other.
