If you're having wierd behavior problems with the robot, first thing to do is check battery voltage! If you put in a freshly charged battery, and it still shows voltage dropping strangely, tighten all the connections in the main battery circuit (those big fat black and red wires that connect the battery to the main breaker, and the PD panel). Be very careful not to overtighten the nuts on the PD.

Have spare parts, including motors, transmissions, chain master links, bolts, nuts, screws, rivets, etc. in whatever sizes were used on the robot. Also have some extra hardware, such as some longer bolts and stuff, and extra structural material like aluminum angle, sheet lexan, etc. to implement last minute design changes.

After you've been thru a few seasons, you will have learned a LOT about how NOT to design and build robots! but every year new things will cause problems, and increase your knowlege.

Most important thing is to remember that every team there will help you, if asked!
