Today after school, my fellow teammates were quizzing me on parts of our 2011 OCCRA robot’s chassis. Since I am a rookie and have never gone through a build season, I didn’t know the answer to a lot of the questions they asked me. I’m not too worried about being illiterate for OCCRA, but since I want to help assemble the chassis for our robot in FRC, I feel that I need to learn some terminology. Can anyone help?
Cheers,

These should help!
I’m sorry, but due to a web filter in effect on my computer (OpenDNS), dl.dropbox.com is blocked 
so I can’t see the link you gave me.
Over on 2168s site we have posted a presentation that we gave a CTFIRST University last year about building competitive drivetrains. It may be a good start for you. Its under the Mechanical Resources section. This by no means covers everything, research on this site through the white papers and various topics will also help you.

Does that work?
Yes, and might I add, some excellent resources.

To be honest you shouldnt worry. You will learn over the offseason what some terminology is. It will come pretty naturally
Yes, that works. I have heard of some of things discussed in the first powerpoint (Omniwheels and Tank and Swerve Drive), but a lot of that stuff is new to me. I knew prior to joining robotics that some science would be involved, but torque and friction? It makes me wish I would have paid attention in my physics class…
First off, I saw that my team’s (FIRST Team 846) powerpoint on robot subsystems was listed up above under the google doc link, and I’m really happy that you guys all find our presentation useful. However, I noticed that the slides in that presentation detailing the physics behind four and six wheel drives (center drop and no center drop) were not present there.
To jwallace15, you may find the information below useful in understanding the physics behind a six wheel drivetrain.

This page covers the various talks we have done at the annual Western Robotics Region Forum Workshops. The full Introduction to Robot Subsystems powerpoint is there (including the drivetrain physics bit), as well as some interesting presentations on control systems, DC motors, and other useful things.
We’re currently working on uploading more updated information to our new website, so please stay tuned for even more useful content!
