Also, you'll want to arrange your wheels differently than is shown in that diagram. I'll leave figuring out why as an exercise to the reader.

the black housing on ours is a little too short in length.
We are actually replacing our housing with spacers to lengthen it just a bit more allowing for the gear to spin more easily and to reduce weight.
We havent figured yet on how we would create an adapter plate to fit the larger FP CIM motor. Too much interference everywhere.

We were able to make a plate for our older AM2 shifters with direct drive shaft at this point for prototyping.

We havent yet tested ours.

To Andy: As we inspected our encoders, we noticed that the shaft does not fully get pressed in there. Is it supposed to be like that?

thanks.

That depends, is the diagram a top view or a bottom?

Very true, Andy Mark just came out with a new set of mecanum wheels. What makes them better then the old set?

They are just a different size. The new ones are 6in in diameter, whereas the old ones were 8in. I do not believe there is any advantages to the new ones other than weight.

There is one advantage to the 6" wheel: it's ambidextrous. A team that wanted spares now doesn't have to buy one more left and one more right wheel and hope two lefts don't break; they can just buy two wheels.

The portion of the Wheel Shaft that has the encoder disk pressed onto it could be a bit longer, but there is enough of a press there for the encoder to function properly. The encoder disk is placed on the shaft before shipment at the right location. If the disk is pressed further toward the circuit board, it may not work properly.

You have to hold a mirror up to your monitor to see the other two wheels.

(or maybe there's a mirror thingy in the cad software?)

wow, lol. Ya inventor has a mirror feature that i use a lot.

FYI,

I've posted most of the AndyMark gears in the FirstCadLibrary. My versions of these parts are more photo and weight realistic. I put these together so I can evaluate the effects of weight reduction operations to these parts.

Andy,

Will the extended SS output shaft found here: http://www.andymark.biz/am-0147.html also work on the Gen 2 Servo Shifters thus allowing the output shaft to extend outside this side plates? If so how far would it stick out past the outside of the bearing?

[JoelP]

I want to replace the output shafts with the extended output shafts but I wasn't sure how I would go about making sure the encoder wheels are in the correct location. Is there any proper way to position the encoder wheels on the output shaft accurately?

[pakratt1991]

We'll be ordering our soon (they should have already been but I think the task was pushed aside, Christmas ) We will also be planning what needs to be done to modifying them to work with the Outback Manufacturing Tank Treads, and also hopefully to decrease some of the weight

This all starts today, so I'll see what we get out of it and let ya'll know

mahalo, mahalo, mahalo......
By the way, how was the black housing painted....anodized, powder coat, ??
thanks.

When I saw it at IRI it was anodized.
