China unveils ground-air dual-mode robot for Mars exploration

A research team from the Harbin Institute of Technology has developed a ground-air dual-mode robot prototype, opening new possibilities for planetary exploration. Weighing just 300 grams — about the same as an average apple — the robot features innovative mobility, capable of rolling on the ground and taking off to overcome obstacles, CCTV News reported.

Designed for extreme environments, the robot comes in multiple configurations, including dual-wheel and spherical designs, allowing it to adapt to diverse terrains. It can also be equipped with robotic arms for specialized tasks. With energy efficiency as a priority, the robot is particularly suited for Mars exploration, where minimal power consumption is crucial.

The research team has developed multiple versions of the dual-mode robot, achieving an endurance time more than six times that of similar-sized devices. By rolling along the ground, the robot conserves energy, significantly extending its operational time. Its modular and lightweight structure allows for customization in tasks such as environmental monitoring, defect detection, and equipment maintenance.

Beyond space exploration, the technology has potential applications in underground environments, such as coal mines and subway systems, where it could aid in construction and exploration of unknown spaces, according to Professor Zhang Lixian from the institute. The prototype has fully achieved these desired features and is ready for broader deployment, Prof Zhang said.
