Testing a Dual-Dwell Safety Gate (Webots)
Overview
A dual-dwell safety gate system is tested in Webots to prevent robot restarts after stopping. It uses hysteresis and a latch mechanism for stability in simulation, though not for real-world use without oversight.

The author explores a safety architecture for robots where perception can stop movement but not restart it, using a dual-dwell system in a Webots simulation. The design includes a 'Doer-Checker' pattern, a reflex layer with hysteresis, and a latch mechanism to prevent premature restarts. The system is tested in simulation and verified through replay, though it is not intended for real-world deployment without human oversight.
