Re: pic: Practice Mecanum Chassis

Awesome design. Nice and simple. There are a few improvements I see possible. Using 25 chain instead of what appears to be 35 will save some weight, because it will allow you to achieve a smaller pitch diameter on the drive sprocket, which will allow you to use a small sprocket on the wheels to maintain the same ratio, resulting in less material in sprockets and a shorter length of chain. Also, the rollers on you mecanums are all aligned in the same direction, and last I checked, they should oppose eachother to actually achieve omnidirectional motion. That's just a small detail though. Also, I'm a bit concerned about the chain on the rear wheels, since when the wheel assembly pivots, the chain will be forced to twist in a bit of an unnatural fashion. Other than that, the design is amazing in the lines of simplicity. And I like the green AM mecanums

[edit] I just realized that AM doesn't have the .step for both left and right wheels, so ignore my comment about the direction of the rollers.
