Abstract
This chapter presents a lightweight operating system for coordinating multiple medical care robots in a hospital environment. The system focuses on addressing concurrency and synchronization challenges in multi-process robot coordination. A centralized coordinator manages task allocation, resource control, and system monitoring, while robot processes execute tasks independently. An all-or-nothing resource allocation strategy is adopted to prevent deadlock by ensuring that tasks start only when all required resources are available. Inter-process communication is implemented using a lightweight text-based protocol for efficient message exchange. In addition, a heartbeat-based monitoring mechanism is used to detect failures and reclaim resources. Experimental results demonstrate that the system maintains correct synchronization, ensures mutual exclusion, and achieves stable performance under resource contention and partial failure conditions.
