You are under no obligation to use the gears, sprockets, or transmissions that come in the kit. You may exercise a great deal of creativity in these areas... and many teams have. You can build your own, or there are also many parts suppliers who can provide alternative parts.

You are limited to the motors in the kit and the pneumatic and control components in the kit, plus approved additions (but not alternatives) as described in the manual.

If your team is designing a robot and has not read every line of the manual, particularly section 8, "The Robot", then you would be well advised to go over it closely, watch the team updates, and keep an eye on the Q&A forum.

It is always distressing to see teams show up for Tech inspection on Thursday who are too large, too heavy, using illegal components or undersize wiring. It takes a few hours to carefully read the manual, but it saves a great deal of pain and frustration on Thursday at the regional.

If you have read the manual and are "just checking"... fair enough, but it is difficult to tell that based on your question.

Good luck with your designs,

Jason
