We finally got a model of Remy printed that we were satisfied with and we painted it to look like the rat. We added the servo motors to the back (glued it using a glue gun) and then added the LEDs. We wrote down the Arduino code for movement of the servo motors and to adjust brightness of the LEDs and soldered the wires so we could keep the battery-powered arduino in the pocket instead of a headband. We have a working model of Remy!
