The topic of today is the Walker. The students built a big cricket (a legged robot) to learn the basic knowledge of mechanical balance and friction. The legged robot is comprised of four legs with a wheel at each end, it can walk power by the motor. The motor axis motions are transferred by a worm gear, and then to the legs. The STEM information behind this section is the basic mechanical mechanism and concepts including the worm gear, friction and balance. All students finished the model and conducted tests by changing the legs’ length to compare the walking speed and balance. They competed with each other and had a lot of fun.
