Power transmission line maintenance robots that focus on repairing broken strands are required to complete complex maintenance tasks in the field. Designing the appropriate mechanisms based on the features of the given maintenance tasks can enhance operational performance and ensure operational quality. In this paper, we present various mechanisms that align broken-strand repair tasks with power transmission line maintenance robots. More specifically, our design focuses on the objectives of walking, negotiating obstacles, and sorting wires, all in conjunction with handling outer environment constraints and the mechanisms of movement, crossing obstacles, and performing repairs. We designed an optimized driving wheel to serve as the mechanism of movement to increase the adhesive force and lessen the inherent track slippage. We also designed passive rotary joints as the mechanism for crossing obstacles to ensure safety. Finally, we designed a spiral resetting-type sorting tool to serve as the broken- strand repair mechanism in eliminating reelinate broken strands. Given these designs, through theoretical analysis, comparative simulations, and experiments, we analyzed the feasibility, stability, and reasonability of our robot design for walking, crossing obstacles, and repairing broken strands.
