Are you using the 4-inch wheels that came with the kit of parts? And are you using a west coast drive (with the center wheels lower)? Thanks guys, and good work on that bot!

We just used the standard KOP wheels and chassis in a long configuration. The center wheel is dropped by .140".

For future reference, dropping the center wheels is not what makes something a "West Coast Drive" (it is merely one portion of it).

My question was around the gearbox. I'm not familiar with the Modulox gearbox, are there one or two of them (I see two CIM's on the back, so I'd assume two??). The output drives a cam that drives a chain?

Two 2.5" CIM motors drove the modulox gearbox. We used a two-slot modulox gearbox. The gearbox had a custom output shaft (8mm with 2mm keyway) that went into a RAW box. Then, a custom hex shaft was machined to interface with two bevel boxes (one at each side of the robot). The gearbox was up-driven 2:1 to offset the bevel box's 2:1 reduction.

How thick and what material were your plastic fingers? I'm going to go back through your videos to see if you mention, but we're using some 3/8 polycarb fingers and we just cant seem to get them to bend to allow the green container to squeeze in even when we push it up against the wall.

We were also wondering what material you used for the plastic fingers. Polycarb? How thick and did you use heat to bend them?

Hey everyone!

I forgot to look at the fingers today while I was at work, but if I remember correctly they were 1/8"-3/16" thick. Also, make sure you use a heat gun on low and give it a lot of passes. To quote our Twitter page, "like a crock pot of corn, low and slow" to ensure they don't bubble and become brittle. You will also want to be sure to have a hard straight edge to bend against to ensure your bends are how you would like them to be.
