Re: pic: FRC488 Octocanum.
I have been waiting for somebody to create this.
Looks like you have the best of both worlds. Where are you going to place the piston? I'm having a hard time visualizing where you'll be mounting it. What configurations are you going to have your wheels in? I.e. four traction only, four mecanum only, 4 traction + 4 mecanum, etc. |
Re: pic: FRC488 Octocanum.
isnt meccum wheels designed to use counter friction...more friction the slower the wheels will go sideways if at all, i just see no advantage to this design...im not saying get rid of it at all im saying prove me wrong :)

I like it, what is the speed difference?
|
Re: pic: FRC488 Octocanum.
Only one is down at a time traction for power then you switch to only mecanum for maneuverability.

That looks amazing,are you guys going to be at the Portland Regional this year?

I like it!
However a few questions Why did you chain all the drive wheels, instead of power one of the directly and derive power off that wheel? How much does it weigh? (without a super structure) Where does the piston mount? |
Re: pic: FRC488 Octocanum.
That is going to be a very fun drive train to watch, just like 217 and 148 last year. How much does it weigh? and Why did you put the mecanum wheels on the outside?

Re: pic: FRC488 Octocanum.
Nice.
You should loop the Jaguar's PWM cable under the front tab on the Jaguar. |
Re: pic: FRC488 Octocanum.
We were joking about making that this year! I'm glad to see that someone did! :D

In retrospect, it would've made more sense to actuate each wheel pod individually, but the system we're implementing is a bit lighter. As a result, we can only run on all mecanums or all traction wheels. Quote:

I tried to make direct drive of the mecanum wheel a reality, but AM's "long" output shafts were not quite long enough to make it plausible. It would've simplified a lot of things, certainly. I am not certain of its weight. We'll try to weight it today, but I'd guess it's around 50/55 lbs. Quote:
Here's some brief video of the first test of the mecanum wheel set. It's nothing too earth-shattering, but I understand that, by the time they left last night, our programming group has field-oriented drive running well. http://www.youtube.com/watch?v=RA-jd48tPFM |
