From Carsten Riewe:

This Baby costume was inspired by the Caterpillar P5000 Powerloader from the movie “Aliens” by James Cameron. The arms and legs are fully movable and the top-light and LED were powered by an 12 Volt battery pack stored in the backpack. The on/off switch is in the left arm. Also in the backpack a Bluetooth boombox ist installed to play mechanical robot sound fx or music if preferred. It took 100 working hours to finish the costume and I built it for the “Karneval”-Parade in my hometown in Germany February 2014 . My 13 months old daughter enjoyed to be carried and moved in her harness safely.
