Boxy robots built from cardboard boxes, foil, and bottle-cap buttons. The buttons are the personality. About forty-five minutes, a medium build: a medium cardboard box per person, a small box for the head, and aluminum foil. Give each robot different buttons; uniform robots look manufactured.

Steps

Cut the eye holes big. You cannot add cardboard back.
Cut the boxes slowly.
Keep fingers clear of the scissors.
Cut head and arm holes in each medium box so they slide over the torso.
Cut eye holes in the small boxes for heads.
Wrap every box in aluminum foil.
Tape the foil down.
Draw dials and gauges on the chest with the black marker.
Tape the plastic bottle caps next to the dials as buttons.
Wrap leftover foil around each arm, wrist to shoulder.
Tape the ends.
Or cut the armholes big enough to slide bare arms through.
Each person slides into a torso box.
Hold or tie the small box on the head.
Tie the elastic string under the chin to keep the head box on.
Crack a glow stick.
Tape it to the chest as a power light.
Optional pro finish: give each robot a name badge, like 'UNIT 7' or 'BEEP BOOP'.
