Re: drivers\coach selection
Ah yes - I forgot about the rules. I don't quiz the kids on the rules. The kids take it upon themselves to quiz each other, but nothing is formal. Until week 6 the potential drivers are usually...

Re: 1.1 Pump (am-3227) Really an improvement?
The problem with the claims of flow rates is that they typically ignore the critical element of temperature. We do not always operate at ambient temp. Our robot compressors are usually too hot to...

Re: Non-marking wheels
You know what wheels don't mark up the floor? Wheels that can be cleaned up after using a mop/bucket, small towel + windex, or any other number of cleaner/wipes/etc.

Re: Custom Gearbox is very loud
@Tottanka -
Inspect the CIM pinion gears themselves. It doesn't matter who manufactured them. In the past, we have received about 1 in 10 pinions as just completely unusable. In one case the gear...

Re: Advantages/Disadvantages of West Coast Drive
We didn't something like this with toughbox nanos for our 2010 and 2014 robots. It wasn't that heavy, TBH. It wasn't as light as we possibly could have made it, but the weight difference didn't...

Re: Advantages/Disadvantages of West Coast Drive
