Are Motors Powered Post-Match?

VEX Robotics Competition Discussion
1

Hey all, high school VEX VRC team here.

We are working on a clamp design to grab the elevation pole and elevate the bot at the end of the game. At this current point, our design requires active motor power or the clamp will slip and the bot will fall. We are getting mixed information about whether motor power is cut (i.e., the competition controller ends the program) at the end of the match. We need to know this as our bot needs to be able to stay elevated after the end of the match, as that is when scoring is calculated.

Our question is:

After the driver-control period ends, does the program end/exit and will motor power be subsequently cut?

This is our first post, so please forgive us if this is a duplicate. If you need any more information, please let us know.

Thanks in advance!

At the end of the match all motors are turned off, yes. Simply having them set to hold would not work.

Got it. Any tips for making a clamp maintain its hold w/o motor power? As of now, we don’t have access to pneumatics.

Most teams use a ratchet. This is a design a made over the summer that fully explains how the hang works. https://youtu.be/IVRtz8LhicI?si=1aUifAhenA8mQ2Zz

You can use a ratchet gear or rubber bands to hold it together if you don’t have acess to pnumatics like my team does.
