Editing Optimal Online Searching with an Autonomous Robot

Title: Optimal Online Searching with an Autonomous Robot

Abstract: This research investigates the problem of online searching for an object hidden behind a corner using a real autonomous robot named Kurt3D. The robot uses a three-dimensional laser scanner to build a virtual three-dimensional environment, helping it plan trajectories, avoid obstacles, and identify objects. The study derives a practically useful and asymptotically optimal strategy that guarantees a competitive ratio of 2, which is a significant improvement over previous studies. This strategy is applied by Kurt3D and documented in a separate video.

Main Research Question: How can we develop an optimal online searching strategy for an autonomous robot to locate an object hidden behind a corner, considering stop-and-scan limitations?

Methodology: The study uses a real autonomous robot, Kurt3D, which employs a three-dimensional laser scanner to survey its environment. The researchers derive an optimal online searching strategy that minimizes the total time to locate an object or explore a region, taking into account both travel time and scan time.

Results: The study presents a practically useful and asymptotically optimal strategy that guarantees a competitive ratio of 2. This strategy is applied by Kurt3D and demonstrated in a separate video.

Implications: This research highlights the need for closer interaction between theoretical studies and practical applications. It also opens up new opportunities for algorithmic research in autonomous robotics and online searching.
