Abstract

An underwater robot based on a variable-size auxiliary drive and a control method thereof includes a variable-size auxiliary drive module and a main control system. The variable-size auxiliary drive module includes a first variable-size silo, at least two first variable-size units and at least two first gasbags. The first variable-size silo has a first accommodating space with at least two first accommodating subspaces. Each of the first variable-size units includes a first micro push rod motor, a first push rod, a first push plate and a first gas guide tube. The first micro push rod motor, the first push rod and the first push plate are accommodated in the corresponding first accommodating subspace. The first push rod is fixed to the first push plate. one of the first gas guide tubes correspondingly communicates with one of the first accommodating subspaces and one of the first gasbags.
