Steering wheel

[radicalnerd]

Our team is looking for a steering wheel to use for next year. We already took apart two old wheels for N64, only to find that they used some sort of optical encoder instead of a potentiometer.

For you teams with a steering wheel controller, what kind of wheel did you use? Or did you use some sort of clever hack, like mounting a potentiometer to the wheel? (we tried that, too)

I know 968 drove with a steering wheel last year. Maybe you can find out how they did it.

It is also possible to de-serialize a PS2 controller output into the OI, so that could be a possibility. Also, a company called Cross the Road Electronics is selling a device that will let you plug a USB HID Compatible wheel into the OI.

67 used a steering wheel in 2005.
I can't remember the exact name of it, but it was a fairly cheap one for the playstation 2. It was blue, grey, and black. And if my memory serves me correct, it had a potentiometer that we just soldered leads to.

what you should do before you take the leap and spend the money is see if you can get another team which uses one, to loan it to you to try out. You may very well not like it.

Personally I've always driven with sticks, and I liked sticks because I had the benefit of tank drive, and individual side control.

But to each his own.

Try before you buy.

IMO I feel you'll wish you had sticks for independent control of each side a stick offers.

One of our team members donated an old wheel to us last year and it has worked wonderfully. It came with a potentiometer. After a short search on Ebay, it looks to be a Mad Catz MC2 Xbox Steering Wheel. Beware that the buttons on the wheel are analog buttons, but I wired them just like potentiometers and they have worked wonderfully.

I checked ebay, and the wheel that 67 used in 2005 was a MC2 MicroCon Racing Wheel for the PlayStation 2. They are pretty cheap and nearly ready, you only have to solder leads to the included potentiometer.

If programmed correctly a wheel can give you all the same control options as joysticks, It will just feel different.

I'm not exactly sure about using a steering wheel... the quick maneuvering changes one has to make when in a pushing match would be tough to pull off with the wheel. If youre using a wheel/caster or skid steer system, or any other system that has motor(s) on each side, I really would suggest just having a joystick for each.

The steering wheel would work if for some reason you chose to put turning wheels on the front of the robot, but like i say i'm just wondering if you can maneuver quickly enough with the wheel. I'm not questioning if you can do it, just the rate at which the driver can correct the path/power output of the robot might be a little sluggish. Anyhow, just my two bits.

I call shenanigans. The robot can be just as quick on its wheels with a steering wheel as it can with one or two joysticks--in each case, the OI is just reading potentiometers and sending the data to the RC to interpret. The challenge in any driver-OI setup is to make sure the driver can reliably and easily command the robot to do what he or she wants. If your driver thinks a wheel is the best way to go about it, go for it. If they want sticks, go for it. But I believe both are like the wheels-versus-treads debate: go with what works for you.

If you think this is the case, clearly you've not seen the many extremely manueverable robots that use wheels. It's all about the implementation.

Hey Cory, might just be me, but I'm thinking that most of the maneuverable robots use wheels, they help you roll across the carpet a lot easier.

btw - give you one guess as to where 668 got the idea to go to a steering wheel.
