I’m done geeking around with mecanum, it’s time to lock in.

How do those odometry pods work? It looks like there have screw joints instead of shafts on the 2 inch omnis, dont they need shafts for the rotation sensors to function?

overall looks pretty good but I’m worried about that HS shaft if you go over the parking zone I think it might get stuck.
It’s screwjoint tech, with bronze and plastic round inserts to link the wheels and rotation sensors together.

I dont think that will work, screw joints dont spin when the wheel moves, the wheel will just spin and then you wont record any rotation. I may be wrong on this, thus is just my experience of screwjoint. Could you maybe send more detailed pictures of just the odom pod?
Correct me if I’m wrong, but I think they have the bronze insert attached to both the wheel and sensor, causing them both to spin at once.

Correct! Based on 606X’s screwjoint tech.

Im still confused how this works, is it one bronze insert in both the wheel and the rotation sensor?
Yes, one bronze insert goes in BOTH the wheel and sensor. So it’s kind of halfway between the two. You then put one green insert on each of the outer sides to fill the rest and prevent wobble. This is why the wheel and sensor are right next to each other, otherwise the insert wouldn’t be long enough.

I like the basic idea, but I’m confused about this part. It looks like there is some part interference.

Fun… but you will still have some work to do to allow the lower screw to fit properly. You will also have to attach those short c-channels with some additional screws in very tight quarters.

Cool idea, but is there a reason you chose this instead of just using 3 wides like 2654E echo? I feel like cutting the c channel loses a lot of structural integrity and could be avoided, along with the suffering of attaching it.

The reason we chose to avoid 3-wides is because they add a lot of weight, and we didn’t think the structural integrity at the middle of the drive would be an issue.

honestly I would just run a 1x1 L channel above the chan to mount the motors, the config above, while it is unique, it comes at the cost of structural integrity with the cutting, and I think it is unnecessary.
Also it looks like the gears are going from 48-36-48-36-36-36-48 (back to front) but like you have a motor on the 2 36t and 1 48t, are you planning to slow down the speed of the motor that is connected to the 48t? btw this 48t that im talking about is connected to you wheel, and so like what is your plan to combat this inconsistency of speeds on the gears?

Oh i see! Thats clever

The outer motors are 3:5 and the inner motors are directly driving the traction wheels… how does that work? Four motors at 360rpm and two at 600. Am I misreading the renders?
Also, how will you plug in the battery cable? Looks like too tight a fit – at the least it would be a very tight turn in the cable.
Looks like a great start to a compact base, but a few things to work out.

It looks like it’s 36:36 so I think they’re running 600 rpm.

The ratios are 1:1 everywhere. We tested the cable, and it will work. Thanks!
