This study was conducted to understand the characteristics of children"s running on the premise that the actual shock causes the child to rotate in a circle with a radius of 0.75 m. The main goal of this study was to understand the characteristics that can be used to create a prototype that simulates the running of a real child. To this end, the jumps of 10 children with different heights and weights were measured and analyzed. First, even with the deviation caused by the location of the child’s running on the floor of the laboratory where the measurement was conducted, it was found that the child"s running was not very consistent with each shock. This situation implies that spring elasticity and specifications of excitation feet must be different for each excitation foot. The average level of floor impact sound for children is 32.6 dB(A) for one person, 37.5 dB(A) for two, 38.4 dB(A) for three, and 40.8 dB(A) for four, and it is reasonable to allow the trial product to generate this level of floor impact sound. However, this presentation level is only applicable to the floor structure performance laboratory of C University"s reverberation laboratory. The time required for a child to run was evaluated to be approximately 8 s, and when converted into revolutions per minute (r/min), it can be said that a motor specification of approximately 22.5 times is required. In addition, the number of applicable prosthetic legs according to the radius of the rotating body was proposed, as shown in Table 5, based on the number of times a child has per three turns.
