What drivetrain style are you using?

[Mike Nawrot]

I'm curious about the ratios of omni directional to tank drive this year. In the past, tank steering has been the standard for all but a handful of teams. This year's game seems to open a huge door for omni directional drive trains though. So what kind of drive train are you using?

So far, the plan is six-wheeled tank, but with the middle set of wheels moved back 3.5 inches since the weight moved back so much for this year's design. Most of the components are on the back half of the robot with the giant trackball in front. We did consider, then tossed out mecanum drive (with regrets) since our apparatus is an elevator after a long history of arms, and the general consensus was try to keep the design to one new element per year.

We planned at first to go with Ackermann, but once we got our previous year's 6WD working with Ackermann controls, we abandoned it for the traditional 6WD. So we have a 6WD that drives like an Ackermann...

6 wheels.

This game will involve a great deal of turning and maneuvering to capture track balls.

It isn't as easy as "go straight turn left."

Our first two years were four-wheels, last year we ventured into the realm of six wheels, and it worked pretty well. THis year, we're going with rear drive wheels and casters in the front. We'll see how it works...

Yikes, based on my experience, you hit the nail on teh head with 6WD... 2WD w/ casters has never worked out well for me

Dualie traction wheels in the centers, dualie omni wheels on the corners, all driven.

I think a 6wd drivetrain is going to be pretty much the best bet in terms of weight/performance balance, and it's ability to hold on in a tight turn.

we are using a flying saucer...

4 wheel drive high traction skid steer, driving 36" wide.

Excellent ability to hold our line in a high speed tight turn

Should be a fun competition, and I expect a very wide variety of robots there

Just curious, has anyone had any experience with the holonomic style drive? (four omnis pointed at 45 degree angles to the robot sides) We were considering using it but ended up with standard tank and omnis in the back.

[Tapoore]

Offset center wheel drive (center wheels pushed 1.5" forward)

The front and rear wheels are just unpowered slip wheels. We have used this setup twice before and it's incredibly maneuverable.

we plan to use the a 6wd with the supershifters

Walking isn't an option in the poll??
Hmmph...

Oh well... guess I will have to go with "Other" in that case.

[DarkFlame145]

we have 6 points of contact on the ground, the front and middle 2 are 2" IFI wheels and in the back we have ball casters. we should be able to turn really well in take mode.

a very similar but yet much improved version of what we had last year.... you get to do the research lol. i'm excited for the improvements
