Building Hobyist Robotkde_rocks (868343) writes "I have never paid much attention to robotics. My daughter is now 6 so we decided to watch all the Star Wars episodes. By the time we got done my daughter wanted to build a robot. Our first attempt was @ Robotic Arm Edge: Wired Control Robotic Arm Kit. But this is rather primitive. Essentially 5 motors which can be driven independently to pick things up.
I now want to build RF remote control unit for the arm and than drive it from my iPhone. Is this possible? How difficult is it? How expensive will this all get? Is there a better starting point?
I know about LEGO Mindstorms NXT but that is too expensive as starter kit."
