[Mentor 2660]

Hello All,

We are a rookie team from Washington State and we've just got our chassis frame put together.

Any comments or suggestions are welcome!



Thanks!

Any wheels in the front?

[Mentor 2660]

We haven't mounted the wheels in the front yet; they are going to be under the plates in the front.

We're planning on using casters -- would some type of omniwheel be better?

[Pelicano234]

Omni wheels are much much better than caster. Omni wheels are more stable and caster are sometimes unpredictabel. The omni wheels at andymark.com morked well for us last year and we are using them again

If you are going to use omni/casters. i highly recommend for them to be placed in the back. With those being in the front it is like driving a car in reverse trying to drive straight in a obstacle course, it will be difficult. So i say switch the wheels, mount the omni/casters to the back so it's more of a smooth turn.

I see slack in the chain, make some kinda of chain tensioner or if you used the toughbox's use the sliders in the mounts that were in the kit box frame. Chain tension is important, you dont want slack.

That's odd, I got to drive our 06 bot (which had two drive wheels in the front and omnis on the back) and it was way harder to drive it forward than backward. It probably depends on the robot and the driver though.

I would recommend testing it both ways to find which set up works best for you guys, if time allows.

HELLoooo from the North East
Looks great I like the set up, you must let the drivers practice every chance they get. ------ Lots of testing and driving ------- Good luck to you and to all the rookies this year ------we all were one once.

I highly recommend omni-wheels as well. www.andymark.biz click on wheels and you'll find them. Most definitely worth the upgrade. We use them in front our robot is pretty drivable with omni's up front. we have used this setup in previous years. Make sure you have no sharp edges! that thing sticking out should be terribly smooth if you want it to pass inspection

Good Luck!

That looks great folks! Keep up the work and get that little guy/gal moving ASAP. If you have the budget, get two casters and two omni's and see what you like better. There's nothing wrong with a little trial and error. What we learned during our rookie year (2007) was that a good driver can go along way to making up for weaknesses in design. The more driving practice your drivers have, the better off you will be.
Good luck in your rookie year!

Any little bump in the carpet and casters will cause trouble. If budget allows go with omniwheels.

BTW Welcome and nice work.

Ball casters work really well imo, we use them a lot and dont have many probs. They are cheap and if something happens to them they can be replaced quickly.

[Astarties]

we used ball casters last year and plan to use them again this year. they worked very well for us. We were able to spin in a dime because we had the wheels in the middle and the casters on the four corners

I agree omni wheels will perform better.
