number of joysticks

[steven114]

The rule book overrides the documentation, and if there is no rule prohibiting it than joysticks should be quite legal.

Any amount u want. Personally, I suggest 5...if u have an alien on ur team that has a few more appendages than u. actually, 3 maybe. 2 for the drive and 1 for an arm or other appendages.

You are allowed to use any joysticks that you want for the competition, so long as you can get them to work. Which is at best a very tedious process unless you know what you're doing.

Your best bet is to buy new ones in the past we were given joysticks from CH PRODUCTS the problem is the one they used to give us is no longer made. The newer version of it just has more buttons including a directional hat. Heres a link:

the good thing is theyre only $20 a piece

But again you can use any joystick you like aslong as you know what the buttons map out to.

I have a question:
Are these ones Serial? Cuz they look really good.

Thanks in advance

They are 15 pin gameport, just like the joystics you recieved in your kit and just like will plug into the operator interface.

Our team has been looking for compatible joystics for a bit now and are probably going to be ordering these - thanks to Xufer for providing the link.

One quick question for teams who have used these before - do the joysticks have yaw control as well? I have examined the CH site and have found no specifics mentioning yaw control.

Thanks, Jeff

im just wondering... the OI reads 3 potentiometers by passing 5 volts through each, and measuring the voltage output. it reads switches the same way. this setup requires 3 pins for each pot, a ground bus and 4 pins for the buttons; thus the DB15 connector

my question is: how do you connect the one asynchronous serial clock/data line in a PS2 controller to all 8 of the above mentioned pins by cutting the connector off?

i might be missing something, but that sounds a lot like magic

if you can find me a schmatic explaining your post, i will be forever in your debt

One thing to try is to put tape over the calibrators to keep them in position.
As for the looseness in the joystick, you can always fix that in the code. My team had a "dead zone" around neutral where any joystick input from 117 to 137 came out as 127. That solved our problems.

pwm01 = p1_y;
pwm02 = p2_y;

if (pwm01 >=117 && pwm01 <= 137) {pwm01 = 127}
if (pwm02 >=117 && pwm02 <= 137) {pwm02 = 127}

This should work.
