Driving

[FrankenmuthK]

Which do you use and why?

Kind of an open question... what do you mean "Which one do you use"... do you mean drive train, or joystick vs gamepad...? Or heck, driving technique.

[DanielPlotas]

Wheels.

[MaGiC_PiKaChU]

my right hand on the right joystick, and my left one on the left joystick

[androb4]

Motors

[T3_1565]

my right hand on the right joystick, and my left one on the left joystick

I'm opposite. I put the right joystick on the left side and the left one on the right side. But only when the robot is facing me.

So I don't get confused.

Saturn Vue

[orangemoore]

Context please.

Motors

Stop being smarty pants, everyone. It's obvious that motors are used to drive -- the OP was simply requesting what physics environment you use to drive. I personally use a few of the Newtonian Laws to help me out but I know others prefer to use alternatives.

If you mean control style:
I've always been a fan of tank, where left joystick controls the left wheels and the right joystick controls the right wheels. Apparently this is harder for some people since it takes mental math and arcade drive removes that portion of thinking. However I have seen how tank allows for a little bit more freedom, especially where there is limited programming skills.

If you mean drive train:
West coast. Yes there are some times where moving sideways is nice, but often underutilized by those who implement it. You can break every bit of chain on your drive train, pop the tread off your wheels, burn out a motor (and yes, all three of these have happened to me), but your west coast drive will just keep trucking.

If you mean wheels:
I personally love the AndyMark performance wheels (http://www.andymark.com/Performance-s/101.htm). Yeah, you do have to buy tread and place it on the wheels, but they perform amazingly. The tread barely wears down on them, we replaced them once last year after our first regional but that was just to upgrade the tread to a tread with a higher CoF. We then ran those wheels for another regional, champs, two off season events, and countless demos on pavement, and I am proud to say those wheels are still working quite nicely. I recommend these very highly for West Coast drive. My preferred tread is the Blue Nitrile (http://www.mcmaster.com/#catalog/121/1290/=whh043) from McMaster. It's down at the bottom marked Abrasion Resistant Nitrile - Blue.

If you want to move sideways, I like the AndyMark Mecanum Wheels (http://www.andymark.com/Mecanum-s/53.htm). I've only used the high load 6" wheels, but they have performed favorably, only problem I had with them was that the practice drive train wasn't built level so it didn't go sideways very well. Other than that, if you're using mecanum wheels make sure the weight is distributed evenly and that all the wheels are situated in the correct orientation and in contact with the ground.

I personally have never used omniwheels in FRC, however one of the rookie teams I worked with tried H-Drive, they used the AndyMark DuraOmnis (http://www.andymark.com/Omni-s/51.htm). They seemed to have favorable results with them, wheels didn't wear down very much. I have used the VexPro omniwheels a little, but not enough to talk much about them. I'd personally go with the AndyMark omniwheels if you were so inclined, I've had favorable experiences with other AndyMark wheels.


If none of this answered your question, please clarify and I will be happy to edit and adjust as needed.

Holonomic/Mecanum

[Poseidon5817]

I have both Callaway and TaylorMade drivers, and on a good swing I can hit 200-300 yards. The key is to swing slowly and be more controlled, rather than smashing the ball. I personally prefer Callaway golf clubs.

[Jaywalker1711]

Personally I drive an Envoy, but my favorite thing I've ever driven is a Porsche

However I cannot recommend their drivetrains to teams because I have reason to believe that they would not be allowed in competition.

The 28 inch pneumatic wheels work well though.

[DanKein]

I prefer an all wheel drive with a high boost turbo. Manual shift please.

[PowerfulKitty]

I don't really like driving and prefer the train.

[Monochron]

This is a good thing to learn about getting good answers to your questions, FrankenmuthK. You have to make sure that the people you are asking actually understand what it is you are asking.

Driving is a much more complex topic than a "which" type of question can answer. What exactly is it that you want to know?

[Ether]

I really miss my '68 Camaro.

Mwuahahahaha. Summer is coming. Golf on your mind much?

[mrnoble]

Mechanimum. Also octoswerve east coast drive. Those are what I driving with.

[Munchskull]

Yes, Driving.

[Koko Ed]

I drive with good intentions.

My neighbor up the street has a 69 z/28 camaro. $$$$

[MaGiC_PiKaChU]

Yes, Driving.

thank you

Just getting ready for next year's golf game.

[MrForbes]

I missed out on this thread....I've been too busy driving my 57 Chevy Suburban all over the southwest, hauling robots to and fro.

Tomorrow I get to drive my 62 Chevy II Altered Wheelbase drag car around town, to make sure it's running ok. Going racing this coming weekend!

[nixiebunny]

I really enjoyed driving my '58 Chevy wagon to yesterday's regional. MrForbes helps me with it.

[GeeTwo]

Hmmm, let's be a bit more complete:

Autos: I drove a '70 AMC Hornet in college named Betch. It survived my six college years (four undergrad, two grad) and several collisions. After mom sold it, somebody eventually killed it by racing it across the Arizona desert without water in the radiator. Next was an '86 Chevy Celebrity (gack - blew a head gasket three years in on legal-speed highway driving) that I replaced about a year after the note was paid off; listed for completeness only, not something I'd ever recommend. My next car was a '91 Jeep Cherokee Sport, which I bought in part because it had essentially the same Rambler engine as the Hornet. It survived both the Metairie flood of May '95 (water line between "Sport" and "Cherokee" on the outside) and a clumsy sugaring of the gas tank around 2000. I sold it for $1 after Katrina to someone who needed a first car more than I needed a second. It was on the road for at least two more years. Now I drive an '05 Saturn Vue, which is now far from "clean", but keeps running like a top. I'll probably get a Subaru Outback when it's time. All of these were automatic transmission, but I have driven a standard, though probably more on the left side of the road when traveling than on the right in the U.S.
Screws and nuts: I prefer my manual pocket screwdriver for small jobs, but usually a DeWalt when powered is indicated. I also use a neat toolbox I bought from the team that was donated by iFixit. (Hey, you gotta shout out the sponsors once in a while, right?)
Nails: I still prefer the old 16 oz claw hammer when appropriate, but I do have a few lighter and heavier for when the need strikes.
Livestock: Just once, when I was about 20. We just had to get about a dozen head of cattle off of US 90 and behind a fence. Mostly a bunch of claps and "Hyaw"s, as we didn't have time to saddle the horses. Good fun, and the owner gave us one steer's worth of beef.
Draft animals: just horses, and those with quite light loads, and not long enough to determine a preference, except that Pancho was much more businesslike than Charlie. (Both names of the horses, in case you're confused.)
Robots: In four years of competition, the team has used 6-wheel skid-steer, 2 wheel drive with two idle omnis, mecanum, and H-drive (now stripped down to omni tank). We also used a 6-wheel skid-steer on the t-shirt cannon, and essentially a "Boe-bot" drive with two traction drive wheels and a transverse omni on some summer projects. I've built small scale linkage and "semi-swerve" drives (only 180 degrees of swerve supported, using four servos) just to try things out. I'd really like to try kiwi.
Golf: never played - and I never drove Ms Daisy, nor any commercial vehicles, either.
Drive controls: automotive, obviously for those things. For robots, we've used explicit tank (two joysticks), arcade, arcade with strafe, and probably some others. My favorite for a holonomic (kiwi, H-drive) or redundant (mecanum, swerve) drive train is a 3-D joystick with a twist axis, using the joystick position for translation and the twist for rotation.

I drove a '70 AMC Hornet in college named Betch.

I've never heard of that college. Where's it located?

[MrForbes]

Ya Betchya college is in Minnesota

[GreyingJay]

I love this thread.

(2012 Subaru Forester, so good in the snow.)

[BL0X3R]

I wanted to try out an idea I had for pneumatic mecanum wheels for drive this year, but the rest of my team didn't think it was a good idea...

[Poseidon5817]

I like to use mecanum wheels on swerve drive so that we can strafe while we're strafing.

[MaGiC_PiKaChU]

I like to use mecanum wheels on swerve drive so that we can strafe while we're strafing.

a junior member actually suggested this for our swerve drive... i can't even

your post got me going for a while

[EmileH]

I prefer velcro mecanum wheels....brownout anyone?

[jvriezen]

The OP has not participated in this thread since the first post. Not sure if it was a finger slip to post before finishing and he/she didn't know how to edit it, or what, but I'm thinking it is possible that repeated bumping of this thread to the top is 'piling on' in terms of making light of the original post and the original poster.

My hope is that this is the last post on this thread.

[lark95]

I like an H drive with swerve modules that have mecnum wheels. this way i can strafe while i strafe while i strafe.:cool: :cool: :cool: :cool: :cool:

[IronicDeadBird]

Don't want to spoil too much but

King Kiwi Swerve drive....
All I'm going to say..

To betray myself as a woodworker's son and grandson:

I prefer my my trusty 20 oz. claw hammer.
