| Risk | Severity | Mitigation Strategy | | :--- | :--- | :--- | | (Finger or limb caught between piston and frame) | High | Limit piston force to <5 lbs; use soft silicone heads; implement auto-reverse on resistance. | | Trip/Fall (Player stepping into a recessed piston cylinder) | High | Cover retracted pistons with translucent but load-bearing grates. | | Projectile (Piston dislodges from mount) | Medium | Use double-locking mechanical stops and daily torque checks. | | Entrapment (Player lingers over a rising piston) | Low | Install optical sensors to freeze game if a limb is detected over a port. |
Initial State (t=0): Pistons A, C, E are UP. Pistons B, D, F are DOWN. Cycle (t=1 sec): Pistons A, C, E go DOWN. Pistons B, D, F go UP. Solution to cross from Left edge to Right edge: Move exactly at t=0.5 seconds (the midpoint), when all pistons are half-extended, creating a flat but temporary surface. piston trap game
