All six wheels are powered in this design.



Well, that kind of defeats the purpose of having the chassis design the way you want it and work to your needs. It also wouldnt be much of a learning experience to just bolt some frame material together.

yeah but it saves money and valuable time.

any other teams weld theirs?

Sorry, Im not really looking for recommendations on why I should use the kitbot chassis.

well i was just putting it out there...............

Now is the time to be designing new drivetrains, and telling a team to just use the kit frame right now is not really a good way to encourage new development and growth. Yes in some instances and for some teams it would be better to just use the kit frame; however, a lot of teams can pull off a better custom chassis that fits there needs perfectly. Also we don't even know if we will be given the same kit frame this season.

i know this, and it was just a suggestion...

i also know that if my team had access to all the tools and materials needed, we probobly would...

i am all for encouragement and new growth, just commenting.......

You should look into having standoffs between the plates. That would add a ton of strength.

Thanks for the recommendation. Ill be working them into the design after I finish finals (tomorrow).

If you have the resources, I would recomend making your own standoffs out of delrin. This way they could be a larger diameter and distribute the load better and still be lighter than aluminum standoffs.

If the delrin standoffs are threaded, they will be much lighter than aluminum overall, but the threads won't hold up real well.

If the they are thru holes, they bolt increases the weight a lot as it is rather long. I'd Imagine an aluminum standoff with tapped ends is lighter than a delrin standoff with a thru bolt of comparable strength,

That is a very good point. I have actually not thought about that before. One nice thing about a thru-bolt with a delrin spacer is that you could buy delrin round stock and make the spacers yourself saving a ton of money. We spent $150 just on standoffs for our drivetrain last year which used COTS threaded standoffs.

We should be able to buy raw stock and tap the standoffs ourselves, so that should be be much of a problem.
