However, the research on indoor UAV obstacle avoidance technology is not comprehensive enough, and there is a lack of summarization of the research results in recent years. This paper introduces the ...

OBJECT ranging can be achieved by humans using the sound reflected or scattered from obstacles. For a range of wave-lengths short compared with the size of its surfaces, and long compared with the ...

In this paper, a real-time obstacle avoidance approach and a trajectory planning method are proposed to avoid collisions to move an object jointly by a human and an omnidirectional mobile robot.
