Re: Category A Crossing?
I suggest using a mechanism that can:
1. Lift the Portcullis
2. Press down one ramp on the Chival de Frise
3. Pull down the Drawbridge
4. Open the Sally Port
5. Scales
This can all be achieved with a mechanical arm that moves up and down from a pivot point on the robots frame, and has two hooks on the end, so that you have a hook facing each way. I would also extend for the portcullis and scale, and with some mechanical genius, it will do all of this. I hope this helped with your robot.

While FIRST's goal is to inspire young people, it will be much easier to do that if we also inspire all the older people as well. - E. Wood [more]
