The composition structure and operation process of mini seafloor crawler drill are briefly introduced. A multi-body dynamic model of mini seafloor crawler drill was established by using Recurdyn software. And then, a mechanical model was established for seafloor sediment based on an experimental study on mechanical properties of sediment soil. Dynamic simulation was also performed for the motion of mini crawler drill on seafloor. Results show that mini seafloor crawler drill runs on seafloor sediment with slight slippage and an elevation angle due to a certain sinking of seafloor sediment. It is found that the dynamic characteristics of mini seafloor crawler drill is significantly influenced by the mechanical properties of sediment (especially thin and soft sediment), and mini seafloor crawler drill running at a lower speed will bring greater influence to its dynamic characteristics.
