Submission + - Building Hobyist Robot

kde_rocks 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.

Comment What about software using these cores? (Score 1) 638

The problem with thousand of cores is not hardware related. Yes, Intel can build thousands of core by continued innovation in the hardware. However, the software community is still struggling to understand how to use even 8 cores. The concurrency issues are enormous. For example look at the following post: Till we solve the concurrency issues the increased number of core will not achieve any higher performance. The C++ is just starting to deal with concurrency. C++0x adds threads support however, that is just the starting point.
