Analysis of Path Planning Algorithms For Service Robots in Hospital Environment

摘要

Medical robotics is an interdisciplinary domain devoted to the development of electromechanical machines for therapeutic purposes. It has the history of 34 years in enabling the new medical treatments by giving physicians additional powers or by assisting them. The pandemic COVID-19 has changed the world wherein humans are hiding in the masks and doctors are highly pressurized to save the lives of humans. On this note, this paper is concerned with the service robots in a hospital ward to offer medication and monitor patients to help the doctors. The purpose of this paper is to compare two well-known grid-based algorithms BFS & DFS and conclude with the optimal path finding algorithm for the medical robots in a virtualized ward of 20x20 grid plan. The results are simulated in MATLAB and it is found that BFS is more worthy in terms of finding an optimal path for service robot in a hospital ward.
