Re: Launcher Safety Ideas

Jim,
It is usually a simple matter of knowing how the solenoid reacts at power on and making that default position be the "parked" position for actuators. Many times, teams do not take the time to distiguish that. If the action does not cause a robot part to extend out of the sizing box no change is made in the design process. Parts should not move until enabled.
