I chose "Robot launches - don't think it's needed for safety" simply because, with our design, it is quite difficult to not know when our robot is armed. It cannot hold a trackball without being armed, and it changes shape significantly to be armed. It simply LOOKS like a catapult.

Plus, it is rather impractical to attempt to add an indicator, considering our design. If we are asked to add one, we certainly will comply, but until then we have not seen the necessity. We have found that other precautions - such as having a knowledgable team member next to the robot at all times, especially when we could be loading the catapult - are much more practical and effective in our situation.
