研究机器人在管道链中反弹逃逸的条件,给出精确退出保证。
Guaranteed Escape for a Bouncing Robot in Pipe Chains
- 通过分段分析矩形管道内的轨迹模式,确定逃逸条件。
- 证明当角度为π/4时,机器人必能从任意长度管道链逃出。
- 结果可推广至带曲角连接的管道,适用于实际机械系统设计。
我们研究点状机器人在等宽正交连接矩形管(称为管道)中的对称反弹运动。通过对单个矩形管道段内所有轨迹模式的全面分类分析,确定了机器人能够逃出的条件。随后将分析拓展至L形管道及更一般的k个正交连接管道段构成的线性链。我们证明了当入射角α= π/4时,机器人必然能逃出。此外,这些结论可推广至具有曲线连接的管道。
原文摘要 · Abstract (English)
We study the symmetric bouncing of a point robot within orthogonally-joined rectangles with equal width, which we refer to as pipes. We provide an exhaustive case analysis of every trajectory pattern inside a single rectangular pipe segment, identifying the conditions under which the robot exits. We then extend the analysis to L-shaped pipes and, more generally, to linear chains of $k$ orthogonally connected pipe segments. We prove exit guarantees for the special angle $α= π/4$. Furthermore, these results extend to pipes with curved joints.
