Chess robot operation via ustream

The chess robot is now up and running via ustream (this doesnt mean its live yet, just that it works). So here is how it goes:

First of all, here is the ustream channel it will be on http://www.ustream.tv/channel/patrickmccb

My first robot..........

So I've decided to build my first robot which not the LMR "start here" one (that one is going to be my second one) and im using this circuit- http://costaricabeam.solarbotics.net/Circuits/Vores/555%20Photovore.png . I've tried about 10 different designs for the body but its just not working. When i cover the left photocell with my hand and the other one is exposed to light the speed of the motors is the same and same with the right photocell. has anyone tried the circuit? did it work?

perfect for putting components like CNY70 in place

Here is the code:

Robots can have children too!

For some time now projects like RepRap have been aimed at self reproducing robots. Although this was not my original goal I have taken a step towards achieving this.

After a few days of trying to get an Arduino to burn the bootloader onto a blank ATmega chip I have finally had some success. As a result, robots lying about my office waiting for repairs are now capable of burning a bootloader into a blank chip.
