Looks sweet, Chris! Any video?

Too bad you guys dropped out of Queen City - we could have violated some OSHA noise rules with the beautiful music our CIM-Sim's would have made together.

nice looking bot. surprised to see no drop will be interested to see how the handling changes if at all.

hopefully will see this in St. Louis

We actually had the center 4 wheels dropped 1/8" initially on our prototype robot and leveled them out because it rocked so much. Turns out, it handles just as well without the drop (If not, better because it doesnt rock now) because our drive base is wider than it is long.

nice looking robot.

What type of wheels and motors are you using for your shooter ?

Is your back bumper at a different level than the other bumpers ?

Rear bumper is about 1-1/2 inches lower for the bridge bar.

Shooter is 2 CIM-sims with an FP and AM motor on each.
Wheels are the 8" hard plastic wheels from AndyMark.
There are two, spaced about 1" apart.

Four motors on the shooter ! How do you account for the differences between AM and FP motor speeds?

Re: pic: CB234 - 2012 R2

The motors are close enough in speed that we have not made any adjustments.

Holy crap. 2 CIMs = 670W, FP(2719) = 170W, AM(0912) = 179W.

That's over 1kW of power. What lead you to decide that you needed ~1000W of power in your shooter?

What motors did you use for your drivetrain?

It is 2 FP motors and 2 AM's in the AndyMark CIM-sim Gearbox. The CIM motors are in the drive.

Whew. Missed the gearbox part.
