Re: Launcher Safety Ideas
All systems that store energy should release that energy slowly when the robot is powered down, but before anyone has a chance to get onto the field and near the robot. By this I mean dissapate the energy over 2-5 seconds.
This means:
1> Pneumatic systems should dump pressure to atmosphere when powered down.
2> Spring loaded and latched systems should unlatch / disengage and dissapate the energy slowly (over a couple of seconds).
3> Winches should release and allow unspooling (especially if used to deform objects to gain spring tension) slowly.
3> Pinch points need to be minimized (watch those 4 bar arms and sissor lifts) while lifting devices are powered down.
Teams should be able to demonstrate these safety measures to an inspector while in the pits. So while just unlatching springs may be safe on the playing field, it may not be safe in the pits.
