Title: a simple robotics project
Post by: dmehling on May 27, 2007, 01:43:22 PM

I am totally new to robotics and I need some helpful advice for the project I'm working on.  It is a very simple robotic arm with 2 degrees of freedom powered by two motors.  I want it to execute a very simple sequence of about four steps, activated by the push of a button.  What is the best type of kit or system to use?  I am thinking about using a basic stamp, but I really have no preference.  My budget is no more than $500. 
Also, I mentioned that input would come by a button, but I would like to try and have it be voice-activated.  The only way I think I could do this is by having a simple software program that is voice-activated which would control this robotic arm.  Is it very complicated to have all input for control be activated by software?

If you are a total noob like me just do the 50 dollar robot kit. It is much cheaper. Afterwards just make more robots when you kinda know what you are doing.(not that I know what I am doing) 8)

I am looking for the simplest method of controlling two motors for my robotic arm.  All I am wanting to do is to have the arm perform a simple sequence of four steps which would execute at the single press of a button.  I would really like to have the input be given from a computer program so that it can be voice-activated.

mcu and have the steps programed into it. use servo's for the motion.  I'm sure certain mcu's can handle the task of voice activation,.

dmehling- please try to keep all posts on the same topic in the same thread, and try not to double post if possible

You can find good information about speech control of a robot in this book:
McGraw-Hill - Robots Androids and Animatrons by John Lovine
Projects are PIC based and programmed in Pbasic, however a more experienced programmer can easily translate the programs in C.

But how would I have the microcontroller setup so the input to activate it would be given by a software program?

once software want the process to start it sends out a high signal out of the parralel port or whatever, and once the MCU receives that it does the preprogrammed steps. once it's done it waits for the signal again

Where would I find a software program that would take care of that process? I need a very simple program that doesn't require programming.
