Task: Make a room double in size in a short period of time, then again, then have a wall shoot up vertically for people to exit (For an escape room). Safety+
Solution: Design and build two 8 x 11ft wall/doors to swing open from an Arduino call. One releases with magnetic locks while the other one uses a custom triple door latch linkage mechanism (see Release Latch). Also, create a sliding wall with damping and an anti-fall safety features.
