so is that used to control your arm during the match? or simply as a mini mock up of your arm?

that is how we control the arm that way it makes it easier for the driver. Trying to drive this arm with a joystick would be toooooooooo much.

so you actually control the real arm by moving the model arm? Do you use encoders or what to measure its placement?

Pots are most likely used. We did the same thing last year and it works sooo nice, as long as you have the time to tune the code to react correctly to the movement in the model. I am curious. How did you guys do it? Is it as simple as finding the difference between the actual and the requested pot values, dividing by a constant and adding the signed int to 127? I'm still working on code for a model, right now we are using joysticks and probably will for competition but its a project of mine.... How do you do it?

we use pots to mesure where the robots are is

well i am sorry i can not answer that not because i do not want to but because that would have to come for one of the kids programing it rob or bharat. Programing the robot is something i can not do but i am sure once one of the guys see this the will tell all,

[uvabrad825]

that is truly awesome...

[pras870]

I must say, that is a genuine idea. I thought about making a potentiometer to create a control for our elevator and/or arm elbow, but it was not nearly as engenious as this. Reminds me a lot of a boat throttle now that I look at it

i saw one of those last year...i thought it was like the coolest thing...great job! (i want one)

wow which team had one

[Nick Fury]

I would like to see a wiring diagram of your controller if you happen to have one.....perdy please?????

crap on me right now i do not have one but i can get you one for the nj reagional

[Greg Needel]

we have a control for our arm also that uses pots to control height.....ours is a little simpler as in we are using 1 knob but we have stops at the common heights ie. top of the goal, hanging height....so it takes the guess work away from the drivers
