pic: Team 148 Robowranglers: Swerve Module and Motors



3 swerve modules, 6 drive motors. All the wheels are driven together, and steered together. You don’t need to turn when your robot has no “front”.

Some swerve module components were manufactured by team 217. The module design was inspired by the 2002 / 2003 Thunderchicken design.

are those custom built gearboxes for the fish?

Harrison’s design lives on :slight_smile:

AM Planetaries ?

Yes, AM Planetaries. John wanted ones that were red anodized, but we don’t have those yet.

148… this is a bold design. It looks wonderful. I can’t wait to see it in St. Louis. Kudos to your team for having the guts to take this path.

ooo! now you are just making me want to see the entire robot…

or is that basically it and a fancy flag pole?

I’m guessing this is it, with a very fancy and robust flagpole indeed. I count 7 victors and no relays on the electronics panel from what I can see. 6 victors for the central swerve gearbox and 1 victor for the module rotation motor (a globe probably) It looks like 148 is gonna be doing a lot of laps this year, I can’t wait to see it in action.

I’ve seen those swerve modules somewhere before…

I think they were pulling our leg the entire time. :wink:

What? Us? Never! …

what that is crazy.!.!!!..

any chance of getting a shot of the other side of the transmission? It looks awesome. Also, what’s the top speed?

Those look absolutely amazing!!! :ahh:
That completely defeated the problem with swerve/krab drive. Having to constantly rewind the wires on the drive motors. This here got rid if that! looks awsome!
possible to maybe get some designs for our summer robot!

Maybe another pic from the other side?

BTW Good luck at competitions!! see you guys at the Bayou Regional!

Wait a minute… there’s balls in this year’s game?! Why didn’t anyone tell us?

In reality, our students decided on our strategy this year. We worked together as a team to brainstorm ideas at the beginning of the season, and they liked the ‘racecar’ idea best. We prototyped and later decided as a team to proceed with the design you currently see. The very nice compliments on our ‘gutsy strategy’ really should be directed to the young ladies and gentlemen on our team who worked very hard on this year’s robot and never faltered in their decision to make it work. It has been a long time since I’ve seen kids this dedicated to their creation.

Last one – don’t want the photo admins to get mad. :wink:

How much does that gearbox weigh?:confused:

Holy cow I don’t know if the main breaker can even handle that much ampereage!

Do you have any trouble with anything popping/blowing if you slam it into forward (or switch directions)?

Awesome! Now I REALLY can’t wait for that video!

Gah…ahhhhh…ummmmm…holy… I suppose not everything in Texas is big :eek:

Speechless. Entirely speechless. Well not entirely…

Elegant, innovative, and a total commitment to a strategy. There’s so much about this robot I like, I had a hard time picking a thread to post in. Perhaps this is the perfect time for JVN to tell us his thoughts on Tumbleweed and the experience the 148 students had in the process. You’ve been really quiet for months and I know you’re watching … and there are so many of us out here that LOVE to learn from you :wink:

:eek: ohhhhhhhh pretty :eek:

Well we’ve seen some bots do 10 laps in 60 seconds, I’d imagine this would have to be comparable or better. 20 Laps is 40 points, add some for auton and you’ve got a winning bot. Can’t wait to see you guys in the big easy ( that is if I get to go :frowning: )

Woah! Very nice!

It’s nice to see the influence of such a prominent team, the Robonauts, displayed all around. Their idea of the V6 seems to have been simplified so wonderfully! I love how you rolled from their enormous system into such a small package.

Bravo!

Not to take anything away from the Robonauts, who clearly have a great design, but it seems like the decision to do what 148 did was simply out of necessity.

If you want to go 20 fps you need 6 motors.

If you need 6 motors and want to use a crab drive, you have to do coaxial crab.

If you want to save weight/complexity, you use 3 wheels.

If you use 3 wheels, you have to use all 6 motors in one gearbox.

I think both are each very much their own designs.
