This letter presents a fully autonomous robot system that possesses both terrestrial and aerial mobility. We firstly develop a lightweight terrestrial-aerial quadrotor that carries sufficient sensing and computing resources. It incorporates both the high mobility of unmanned aerial vehicles and the long endurance of unmanned ground vehicles. An adaptive navigation framework is then proposed that brings complete autonomy to it. In this framework, a hierarchical motion planner is proposed to generate safe and low-power terrestrial-aerial trajectories in unknown environments. Moreover, we present a unified motion controller which dynamically adjusts energy consumption in terrestrial locomotion. Extensive real-world experiments and benchmark comparisons validate the proposed system’s robustness and outstanding performance. During the tests, it safely traverses complex environments with terrestrial-aerial integrated mobility, and achieves 7 energy savings in terrestrial locomotion. Finally, we will release our code and hardware configuration as an open-source package.

The video presents the paper Canfly: A Can-sized Autonomous Mini Coaxial Helicopter.
The development of autonomous rotary-wing UAVs has shown an evident tendency in miniaturization. However, the side effects brought by miniaturization, such as decreased load capability, shorter flight duration, and reduced autonomous ability, seriously hinder the process. In this paper, we firstly investigate into the configuration of different rotary-wing aircraft and optimize the configuration selection. Afterward, with several elaborate mechanisms contributing for the miniaturization, we present the hardware design and control strategy of a mini coaxial helicopter, which is 62% smaller than the smallest autonomous quadrotor so far [1] in the collision area. Abundant experiments reveal that it achieves impressive traversability and is capable of carrying autonomous tasks in unknown dense scenarios, while maintaining satisfactory performance regarding loadability and flight duration.
