Average 2014 Chassis

[Richard Wallace]

AM14U with a few enhancements:


Asymmetric square setup 28"W X 27.5"L
Four AM Performance Wheels w/Nitrile Roughtop
Two VexPro Dual Omniwheels
#25 Chain Drive with simple tensioners where needed
AM3CIM4U refitted with VexPro gears to decrease friction
Grayhill encoders on custom extra long standoffs

Asymmetric square setup
Or just "rectangular" :)

Looking really good though!

Or just "rectangular" :)
The square is not exact because we left some margin on the frame perimeter (111<112) :) . I like to make things easy for our inspectors.

But what I meant by "asymmetric" is that the wheelbases are not the same on each end; i.e., the middle wheels of this 6WD are not in the center of the chassis. We cut one end of the kit chassis, but not the other. It is also possible to cut both ends and obtain a "symmetric" square chassis, with the middle wheels at the center of the chassis.

Why do you list substituting chain for belts as an "enhancement"? :p

Why do you list substituting chain for belts as an "enhancement"? :pWe really like the belts with 2 CIMs per side and kit wheels. No data yet when we increase to 3 CIMS, and increase to roughtop CoF. We ran 3 CIMs per side with roughtop and #25 chain last year with no issues, except that we kept delaminating the AM roughtop when pushing hard. This year we are switching to nitrile in an attempt to avoid that.

Short answer: belts might be just fine, but we are going with what we know works this time.
