The compound eye from DAGU, designed by Oddbot, is cool and cheap. But I needed a round board to imitate the human eye, so I made one by myself. The IR LED's and photo transistors are the same as in the original design. As I had no PN 100 transistor, I used a BD 139 (the 4 IR LED's draw approx. 100 mA @ 5 V).

6 DOF robot hand finished

I finished the 6 DOF robot hand for my project Te no atama today. Here are some pictures. The thumb has two degrees of freedom. The primarily function of the hand is to display hand gestures. A 2 DOF wrist will be added. All servos have a metal gear and are digital.
