Overview of the proposed autonomous transport system.

Caption

(A) Object transport demonstration. (i) The full process of lifting the target object. After the tethered UAV autonomously performs knotting on top of a tall building, the winch reels in the tether to lift the object. (ii) Autonomous knotting procedure. The UAV first performs object enclosing, then enters the tether search state, and finally executes tether binding to complete knotting. (B) Radar chart comparing the proposed system with other state-of-the-art aerial/cable-driven transport robots, including the commercial high-payload multicopter (DJI FC 30), commercial high-payload helicopter (Blowfish A2G), and a portable wire-driven parallel robot (Cubix). PWR (payload-to-weight ratio) is the metric describing the ratio of the maximum payload capacity to the weight of the robot. The outer ring of the radar chart is color-matched to the best-performing system for each corresponding metric.
