My Moebius Models 1/6 Lost in Space Robot build. I used brass and aluminum tubing to strengthen the connecting points of the treads and lower torso. I also made the model easy to disassemble to add more electronics, including the voice box/light and ambient sounds. I will do this at a later date, as well as replacing the bubble (I don't like the seam) and Lighting the Bubble. His upper torso and Head can be manually rotated. The batteries are hidden in the tread section as is the switch.
