Voice recorder board finished and assembled. The loudspeaker (0.5 W/8Ω) is from an old toy, came in nicely in a small plastic box, which covers the speaker and improve the sound (soundbox). Some basic programming done, see video DOC_0002.

This is one of my projects, I wanted to share with you before I am going to holiday. Inspiration for the robot was the DRK8080 from Doctor robot, hence the name DOC. So far I have finished the 5 DOF robot head. The head was partly designed with Google Sketchup, mainly to avoid faults in construction. I can only recommand this, even your robot is much simpler from the mechanical point of view. Tools and materials I have used:
