Double-track chassis synchronous walking system and using method

The invention discloses a double-caterpillar-band chassis synchronous walking system and a using method, the double-caterpillar-band chassis synchronous walking system comprises two walking chassis mechanisms, and each walking chassis mechanism comprises a caterpillar-band chassis assembly and a rotation assembly; the driving wheel module comprises a driving wheel, a walking encoder, a support and a first gear pair. The rotary driving module comprises a motor, a speed reducer and a rotary encoder, and the rotary supporting module comprises an inner rotary pipe disc, an outer rotary sleeve and a second gear pair. In the invention, the deflection angle difference between the walking chassis mechanisms and the telescopic sleeve frame mechanisms in the column units on the two sides is monitored in time, then the stroke difference is calculated, and the walking speed of the backward walking chassis mechanism is automatically fed back and adjusted according to the stroke difference until the stroke difference is co
