Department of Robotics Engineering in Tokyo Metropolitan College of Industrial Technology has many researches. In the author's laboratory, developments, experiments and analyses of various children's toys have been carried out. For example, boomerangs with three wings, Plastic Bottle Rockets, boomerang stunt planes, flying rings and boomerang dragonflies are developed and analyzed by simple equations of motion The analytical results can explain the experiments. Two-legged walking toys equipment descends slope, while vibrating a right and left arm up and down. The vibration of this arm is called a rocking vibration. Relation between angle on slope and shape of legs is solved by Principle of conservation of energy. Moreover, relation between shape of legs and rocking vibration is solved by Newton method. Two-legged walking toys which children can manufacture were developed with the analyzed shape of leg.
