Re: pic: Chassis Idea

This is a great time to be learning how to CAD a chassis, and asking for suggestions!

Some comments...

A short/wide chassis can be kind of tippy in games that involve using arms and such. Might want to also work on a long/skinny chassis design, so you can have experience with both when you discover what the 10 game is and figure out what would be best for it.

The main circuit breaker should be near the outside of the robot, so it's easy to access after you put all the other "stuff" on the robot. Also the battery should be easy to change quickly. Having it stand up is often a good idea...

The corner gussets are neat, but if you make the bottom plate out of something that is even slightly strong, they are not needed. Learn about shear strength.

Plan on two motors per side for the drivetrain, it's usually the way to go. Lunacy was a rare exception.

Think about bumper mounting. If you build it into the chassis design concept, then it won't be a difficult issue to deal with during week 5 of build season...if bumpers are indeed required next year.

Also be sure to work on a design that uses legs instead of wheels, you never know what the GDC will think up!
