In order to detect the origin of life and the development history of the planet, Mars sample return has become the main task of exploring Mars by various countries, and Mars aircraft exploration is more efficient and has a wider exploration range. Using a Mars aircraft to perform a Mars sample return task can collect scientific samples from a farther place.

When the existing Mars aircraft is deployed on the ground, the device needs to be moved from the landing to the surface of Mars as a whole, which causes the mechanical arm to bear a large load and increases the risk of mechanical arm failure. In the extremely harsh maintenance conditions on Mars, the influence and loss caused by the deployment of the aircraft are difficult to estimate. The deployment method is affected by the surrounding terrain, has low adaptability, and affects the deployment efficiency and quality of the aircraft.
