Ghost In The Shell movie left a long lasting impression on me. The tank from the final battle captivated my mind. It has such a rigid shape, but then moves in a very fluid way which makes it seem more like an animal, and then it becomes completely static making it purely mechanical again. Now I realise that this was something that I wanted to build for a long time and I just had to get it out of my system :)

It took roughly ~250 hours of 3D printing time... and probably even more time for polishing using acetone, sand paper, files and putty. It is actuated by 28 servos and driven by 2 Raspberry Pi micro controllers with custom software for locomotion and animation. It has two lasers (serious, how can you have a robot with lazors?!!!:) It can be controlled by PS3 joystick, but it has some autonomy as well - it can track and follow faces.
