Very nice work! This is about as simple a box frame chassis as I've seen, and it is definitely a good start towards a top notch final design.
Some things to think about when designing a chassis (obviously some of these are dependent on the game and rules):
- How will we ensure that our chains will be properly tensioned?
- How we will adjust the drop of the center wheel (if any)?
- How will we mount our bumpers?
- How will we fix X when it fails? X = wheels, sprockets, chain, gearbox, motor, speed controller, cable, frame members, welds, etc. (and how long would such a repair take?)
- What sorts of COTS and custom made spare parts will we want to bring to competition with this drive base?
- Do we have easy access to all bolt heads, nuts, rivets, etc., for tightening or loosening?
- If something must go to make weight, where will we start?
- What is the center of gravity, and how can we move it to where we want it to be?
- How long will it take to build this once build season starts?
- How much does it cost? Can we lower the cost somehow?
- What are the wiring paths?
- Where can we put the battery?
- How will we lift this thing?
Hope this helps!
My only two questions/comments about your particular chassis are (1) if there is a ramp to climb, you will probably want to move your wheels further to the front and rear of the frame and (2) how do you plan on supporting the plywood base in the middle?
If your logo is your team number in a font 4" tall in 1/2" stroke, colored/outlined in white, then yes.
Otherwise, no. - cadandcookies [more]
