Last Halloween I built a robot costume out of laundry detergent bottles, crutches, football shoulder pads, and several stoned days with a hot glue gun.
Step 1: Gather Materials
I spent a week raiding laundry mats trashcans in search of empty bottles gathering about 60 of assorted shapes and sizes. I also found two pairs of crutches (for stilts), and a pair of football shoulder pads.
Step 2: Stilts!
I found a wooden pair of stilts at a thrift store, they raise me 18 inches off the ground. The stilts have a platform for your feet. I used a few screws and some epoxy to permantly fix a pair of shoes to this platform.
Step 3: Leg Construction
I used 8 Large Clorox bleach bottles that I cut the bottom off of, after that I cut the cone shaped top off so I end up with a cylinder of plastic. I also found 2 small cone shaped wastebaskets, These I inverted so the wide part is at the bottom and around the bottom of the stilts via a small hole I made in the wastebaskets.
From here I started to add the bleach bottle cylnders one on top of each other (note I had to cut away a place for my shoes in a few of the bottles.) Once they are all in place I hotglued everything together.
Step 4: Robo Claw
I cut 4 handles from some square laundry detergent bottles to use as the fingers. These I glued to one of my friends hair clips, 2 on each side so that they close together like a claw and can open. I put the hair clip on a dowel and glued it through a small cut up bleach bottle cylinder.
