Looks good, a driving platform done back in the first week will be advantageous for the drivers. How many students designed this?

Also about the 90* serial adapters. Do you have one on the radio too? I'm not sure if that is exactly legal, but looks relatively clean.

It doesn't look like you are direct driving a wheel.
Do you have a back up plan if your chain falls off?
just wondering, because it would be hard to drive with one side...

I am a Rookie coach here, so correct me if I am wrong please, but I thought the bumpers had to be 2.5" off the ground.

Your design is very inspiring. I have students who are making a catalog of pictures for various designs. They had made direct reference to yours as something they want to try and build during the off season in terms of the dewalts and 6 wheel drive.

The adapters were purchased from www.l-com.com.

You may have enough room, I can not see exactly how it fits in and it would be easier to fix it now if you need to.

The new batteries fit after a bit of gentle suggestion.

We're really happy to have had a lot of time to practice driving with this and to let the students get a feel for it. It'll be advantageous, we feel, and that's why we worked very hard to get it done as quickly as possible.

We had similar adapters on our RC last season and were able to pass inspection at three events. We're not expecting any difficulties this season, either, but you never can tell.

I don't expect the chain will come off. The chain is aligned well and tensioned properly. It hasn't yet come off in testing on this chassis or its predecessor.

Figure 8-2 in The Robot states "bumper must remain between 2.5 inches and 8.5 inches off the floor." Since the bumper is 5" tall, there's some play there for mounting things and so we'll probably move it up as high as it can go as a result.

The Nothing But Dewalt white paper here on CD is a great resource for teams interested in trying a project like this out. We made a handful of very small changes -- the sun gear pressfit, the servo mount and the overall mount -- that we'll probably detail later on in the year. Most of these changes were made to suit our capabilities better and so that we could feel like we put a little bit of thought into the design .
