Suppose one of the servos stops shifting... Then you'll have two gearboxes chained together running at different speeds. The DeWalts will strip themselves, and you'll lose half your drive train.

Yes, it is an unlikely scenario. But its the kind of disaster that could ruin your day.

This is a possibility. If the servos do not shaft at the same time one or more of the following might happen:
The Dewalts might break (they are very strong)
the CIM might burn out (unlikely)
the sprockets might break
the chain might break

If this happens it will be bad.
The plan is to have another 1 or 2 spare side modules ready to go on. It will be able to come on and off in just a few minutes, to we will be ready to drive again in the next match.

If the drivers realize that this is happening during the match they might be able to shift one dewalt into "neutral" (between 1 and 2 or between 2 and 3) and use the other one.
I really don't know how likely this is.

Originally posted by richardmcc2 It wouldn't be quite as risky if you didn't chain all 6 wheels together...just connecting the middle wheels to the back wheels...I would probably try that first and see how it drives before added a second set of chains. On the other hand, I have seen other teams like 418 use this configuration successfully with no shifting problems

This might help. If the wheels didn't shift at the same time the wheels would slip a bit, but still much less harmful.
I chained them all together because that way each of the 6 wheels has the power of 2 CIMs. If you did what you are saying you would not have as much power to each wheel itself.

I haven't finished the electronics yet.

I'm intrigued by your frame design. What made you do the two triangles?

This would make manufacturing it take a bit longer, as well as welding it slightly more difficult. I personally would have just run the bars straight across, which would have also given more area to mount to for other mechanisms.

Looks like and interesting idea, good luck with it!

Yeah, the triangles do add some complexity. The reason i didn't put one bar across is because that way there is a rectangle. I usually try to use triangles when possible because they are stronger in general. Your idea may be better though, I'll think about it.....
