My final post for this Thanksgiving weekend. I think that being able to identify motor overload is one of the more useful things that a coach or mentor can do, as it often points to a design flaw — and the sooner those can be identified, the better!

As promised, here's my follow-up to the Gears & Torque Crash Course post, explaining how you get speed or strength greater than 7x (the difference between the smallest & largest VEX gears).

Don't be afraid to open up your motors to check out the gears when things don't sound right. Here's a primer on what you'll find when you open up a VEX motor and how to figure out if there's something wrong.

If you're starting your Starstruck robot now, you're ahead of the game! Take your time and encourage your team to brainstorm, sketch, and prototype as many ideas as possible. The ideas don't have to be pretty, practical, or even made out of VEX parts to be proof-of-concept.

I strongly recommend labeling all of your motors and your motor controllers and other wiring systems so that you can quickly troubleshoot problems. It will also save you a lot of time when you have to unplug motors or wires in your design iteration, so that you can get things back together quickly and correctly.

Plugging the motor into the motor controller -- connecting red-to-red or red-to-black do different things. Find out how that works and what it can accomplish. Also learn about how 3-wire cables must be connected.
