I've got a 12v robot arm for a project that I am doing. Now normally I'm a mechanics guy. I like to put stuff together, then watch someone else hit some smarts into it, but this time I've got to do the smartening. I'd like to program it in labview since its the only real programming experience I have. So, my main question is, is there a simple/cheap microcontroller that can run this arm, and run it with labview.

Any hints for a noob?

Hey,

There might be, but you will have to let people know what motors are in the arm. Servos, DC motors, stepper motors? See if you can post that info with any model or serial #'s. That will help forums members to help you :)

Cheers,

this should be the exact same arm http://www.rhinorobotics.com/xr3_flyer.html

Thanks for the help.

edit, I don't have either of the controllers for the arm, just the arm itself.

I believe you can use the LEGO NXT kit. There is a third party servo controller (http://www.mindsensors.com/index.php?module=pagemaster&PAGE_user_op=view_page&PAGE_id=93)that can control 8 servos, and it should work with Labview (http://zone.ni.com/devzone/cda/tut/p/id/4435).

I'll do some more digging, but I think that is all correct.

Also, if you do end up going with a different controller, there are plenty of people on this site who will be more than happy to help you get going.

Do they have a similar thing for sensors, because each of those motors also has a built in encoder, and the encoders are really important to the project.

I know that there is a FIRST competition which runs off of the NXT controller and technic(?) stuff. Would that motor/sensor controller NXT addons work?

I've seen bigger breakout boxes (http://www.mindsensors.com/index.php?module=pagemaster&PAGE_user_op=view_page&PAGE_id=67&MMN_position=29:29) for sensor inputs, I just can't seam to find one as of right now. That said, using two of these should give you enough inputs for this project.

Hope this helps, and keep us posted on your progress.

Are there any other controllers other than NXT, mostly out of curiosity.

Also hitechnic (http://www.hitechnic.com/) do a range of sensors and motor controllers.Their sensor multiplexor is also cool.
