Lieutenant Dan is my entry in a junkbot contest. The "sponsor" wanted humanoids. I think Lt. Dan qualifies as a humanoid, even though only the top half of one.
Lt. Dan is mostly made of my old Erector (Meccano) set that I've been carting around for about 25 years. The servo brackets are just bent girders. There are a total of seven servos; three in each arm, and one to pan the head. Object avoidance is via a Parallax Ping))). The brain is my pseuduino project running an ATMega168. All the parts were things I already had, resulting in a total cost of nothing (although I had to "borrow" servos from my R/C trucks).
Sorry I forgot to put this at first. Lt. Dan definitely drew inspiration from fritsl's skiwalker.
Still to come are further refinements to the code, and some kind of rubberized grips for the hands.
Here's Dan after an unfortunate encounter with the refrigerator. Instead of reversing he managed to tip over forward and break his neck. This also prompted me to re-code his arm positions.
Here's the picture that made me realize the head was kinda creepy.
And here's his sharpied smiley face and Darth Vader helmet. Slightly less creepy this way.
*UPDATE March 24, 2009*
There are more photos here. Some zoomy-er shots of the ghetto servo brackets and such. I am going to consider this particular one complete now, mostly because I want some of the parts back. I will, however, revisit this platform in the future with higher end parts.
