Introduction: Frankenbot

This is Frankenbot he is a toy robot with 2 modes of propulsion, foward and reverse speed, 180 deg. turning ratio, and is comprised of other toys(minus arduino/breadboard and components)....
The main body, rear wheels, battery pack, and motor are from a cheap rc car i bought at a garage sale for a $1, this is the first mode of propulsion.
The front wheels and the rest of the upper body are made from an erector set.
The steering servo, motor and prop are from a rc airplane, this is the secondary mode of propulsion.
The lipo battery pack and esc came from a losi rc buggy
And of coarse the brains of this monster is an arduino uno microcontroller and solderless breadboard.
Addition components used were jumper wires, twisty ties, duct tape, cardboard box, and a voltage regulator.
