Why don't I ever see robots that steer like a car

Wait.....the field has secret CO2 grapnels built in to sling your robot around the corner?

We're working on control changes to make this as easy as possible....which kind of does away with the need for a robot with car type steering. First tests on it yesterday were very successful.....6wd, driven with a (spring loaded to return to center) steering wheel and throttle.

I think you also need to assume the ability of the field to withstand the same impact, as well as the ability of the center alliance drivers to withstand the repeated assaults on their senses.

Are you talking about the operator interface?

[MrForbes]

yes, I am talking about the OI.

Our testing program involves the use of a field mock-up and one of these...

So if Batman is not the appropriate movie, would it be more like Austin Powers on the cushman or Herbie fully Loaded?

Our team is working on a steering method that simulates the driving of a car in a racing game. Rather than going with a load of complicated sensors, we're planning on coding everything in algorithms that we can change easily whenever we need to. We're planning on having incremental steering for the front wheels and a differential gear system for the rear wheels.

[Team 135]

We thought about it and thought that it should be good for this competition. The main reason that we did not do it was because it was complicated. Not that we could not have built it and gotten it to work but there are a lot of places that failure could happen. Our goal for this year from pre 6 weeks was to keep it simple stupid.

[MrForbes]

We built a prototype Ackermann steering robot using the kitbot chassis, it was quick and easy to build and worked ok, but the steering radius was pretty large and we also figured out how to make a 6wd skid steer more controllable...so we gave up on the car steering idea.

[FIRSTMa2104]

We saw the same problem but we fixed it by changing the size of the wheels.

[Kendal Reed]

We're doing it. Our drive team may regret it once they see this thread, but... we're doing it now.

(Ours will be rear wheel drive only, with each rear wheel connected to a pair of CIMs via one gearbox and the differential functionality handled entirely in software.)
