First time help needed
« on: July 17, 2007, 05:40:17 PM »
I'm totally new to this forum and to robotics  ;D as you'll find out soon.
I need some help I don't really know what to buy basically I'm after something that will control two servos. Something I can adjust without a computer if possible. It's for a robotic arm and somehow it has to work two servos independently  with a touch of a button i need it to be able to work in one direction and with another press of a button it has to come back to the same place. also with adjustable settings. Ive been looking for a long time but i always find something thats either too much to buy or doesn't do all the things i need it too. ???   hopefully someone in hear could find me something  Thanks everyone  8)

Check out basicatom.com, they sell something you can use to make it.  A basic ATOm chip can control the servo, and while the basic atom is TECHNICALLY a computer, its not a big box, its a very small(think like 2 or 3 match boxes) chip.  You can program it to accept input from something, and then to control your servo's.

What you seem to be wanting is a servo controller:

There are a lot out there, so it may take a bit to understand the differences between them all.

I just joined this forum to ask for the same thing, I know quiet a bit about robotics and been looking all over for something like that,  I basically want the servos to go to a pre program position in order i programed to, then with the other button the same pattern backwards.  most the servo controllers (or all of them) don't have inputs but the usb or parallel cable. witch i need two. it will help a lot if some one more experience could come up with a way to handle this.

here you go i think i got the answer, i just remember that i used the Parallax basic stap robot call boe-bot back in high school and was able to control 2 servos for it wheels, they sell just the electronics in a different kit. you could program different input into it. i remember that the robot had to whiskers (simple switches) in front of the bot that if it bump into something it will do what ever you program it to do. so i'm going ahead and buying the kit and see what i can do. I'm doing a sequential car shifter that will convert stock H patter transmissions into a sequential shifter just pull back to up shift, push to down shift, therefor my two inputs
