hey does anyone know where i can find a small robotic arm? maybe on a small backhoe or other escavator RC? the smallest i have found was 7'' arm, but i'm looking for something around 3-4''. thanks
How many degrees of freedom are you looking for?
[link=http://www.lynxmotion.com/c-27-robotic-arms.aspx]Lynxmotion[/link] has some. One that is 5.75"
And the [link=http://www.lynxmotion.com/p-160-little-grip-kit-with-servos.aspx]Little Grip Kit[/link]
Also, try VEX kits to build you own.
