The chicklets work great. You may not be able to do everything with it, but you sure can do a lot. For something like a steering wheel though you may want to read the IFI instructions FOUND HERE and read the user manual and check on page 6 how to calibrate it than let us know if you have any more problems.
Does anyone know which steering wheel by Logitech we can use? There are several types. We just ordered by mistake 3 Logitech Momo ones that needed an external power source. Ouch!
We found one on amazon called the Xbox Logitech Nascar Racing Wheel.
Can anyone confirm that that is the right one before I buy a few?
I was thinking about using the chicklet for a wheel, but then I heard that you can open up a wheel and wire the potentiometer inside to the desired port on the oi. I think that may take a little more work than just plugging in to the chicklet, but it would be cheaper… Has anyone actually done this? I have yet to try it and I’m not sure which wheel to buy. I’m also still entertaining using the chicklet for a wheel if that doesn’t work.
I can tell you from experience that the Logitech Nascar Steering Wheel works well with the robots, however it was a lot of work and basically had to focus on it for the entire build season. Here are some things to think about:
With skid steering (either 4-6 Wheels or tank treads) the zero-turn radius of the robot will not be as intuitive as two joysticks.
The steering wheel is much more accurate, linear, and stable with regards to PWM signals to the controller than any joystick I have tried.
There are two pedals to work with (possible reverse accelerator).
There are shift paddles and several other buttons on the wheel, however you must figure out bit masks to use many of these buttons because they are passed to the controller through the unused y axis.
Don’t be afraid of standing while using the pedals on the floor, and remember to give your drivers time to practise and take their feedback to improve the system. Oh, and make sure to thoroughly read and understand the chicklet documentation.
As of now, The USB Chicklet only supports the NASCAR racing wheel. It is my understanding that that device is no longer in production. When developing the Chicklet we wanted to support a variety of control devices. Ironically we picked the NASCAR racing wheel because of it’s availability. We do write custom drivers if there is a particular device a team would like supported. There is a charge for this service. It is $25, per device, per Chicklet and $10 for any additional Chicklets. The device must be of the HID class.
