Overview

Randomized trial evaluates a new algorithm for path-planning in cable-driven hyper-redundant robots, enhancing stability and effectiveness.

Key Points

  • The aim is to improve path-planning for cable-driven hyper-redundant robots in confined spaces through an efficient algorithm.
  • Developed a path-planning algorithm based on the Soft Actor–Critic framework.
  • Designed a reward function and path smoothness index to enhance path stability and feasibility.
  • Employed Hindsight Experience Replay and Prioritized Experience Replay to tackle sparse-reward scenarios.
  • Algorithm reduced computation time by 96.56% compared to RRT* and 97.95% compared to As-RRT.
  • Showed a 14.9% improvement in path smoothness and a 10% increase in success rate over As-RRT in real-world tests.
