Review of Key Technologies of Rotary-Wing Mars UAVs for Mars Exploration

Abstract

The sparse atmosphere on the surface of Mars provides the necessary flight conditions for Mars unmanned aerial vehicles (UAVs) to perform low-altitude flights. This work presents a comprehensive overview of key technologies in the development of Mars UAVs, with a specific focus on rotary-wing Mars UAVs. It summarizes prototypes of rotary-wing Mars UAVs developed by various global research institutions. It reviews essential technologies in rotary-wing Mars UAV research, including the Mars near-surface atmospheric environment, aerodynamic characteristics, and principles of low-pressure flight control. This work also summarizes various experimental setups and ground test results for rotary-wing Mars UAVs. Furthermore, it discusses the future development trends of rotary-wing Mars UAVs.

Strategies for Optimized UAV Surveillance in Various Tasks and Scenarios: A Review

“…As technology advances, human expectations for the exploration of other planets in space are increasing, with two of the most notable targets being the exploration of Mars and the Moon. The communication delays between Mars and Earth mean that robots must have a certain degree of autonomy, able to make decisions and operate without real-time commands, and at the same time, the complex and changing terrain of Mars poses a challenge to the robot's navigation capabilities [249][250][251][252][253]. The past idea of simply using unmanned vehicles for exploration appears to be inadequate in the face of these challenges, which calls for an increase in the synergy between UAVs and unmanned vehicles in the Mars This calls for increased synergy between UAVs and UAVs in the Mars exploration process to address these issues.…”
