Chinese Scientists Developing Mars Drone That Can Roll and Fly (space.com) 4
Chinese scientists are developing a lightweight Mars drone capable of both rolling on the ground and flying using contra-rotating coaxial rotors. Space.com reports: The air-ground dual-purpose unmanned aerial vehicle (UAV) weighs only 10.6 ounces (300 grams), equivalent to the weight of an apple. The development team is at the School of Astronautics (SoA) of the Harbin Institute of Technology. Seen as showing promising potential in future Mars science work, the UAV can take off at any time, traverse obstacles, and boasts superb endurance, reports state-owned China Central Television (CCTV).
"On the ground, it mainly rolls by shifting its center of gravity," said Zhu Yimin, a Ph.D candidate at SoA. "In the air, it relies on a pair of contra-rotating coaxial rotors, controlled by a steering engine to adjust the forward direction, to control torque and force, ultimately achieving stable flight," Zhu told CCTV. The UAV work entails multiple models of air-ground dual-mode robots with different configurations, CCTV reports. These robots move by rolling close to the ground, which reduces energy consumption, and can achieve a flight endurance time of more than six times that of traditional drones of the same size.
According to Zhang Lixian, a professor within the SoA, the hope is that the aerial vehicle can show off its long endurance and observational abilities on Mars. "Our second goal is for such machines to be suitable for construction in many underground spaces and for exploring unknown underground spaces. We also need robotic means for inspection and environmental detection. We have now materialized all these functions," said Zhang. A video of the drone can be found here.
