There are 6 bags filled with parts that come in the box, so assembly is required. Even though the instruction book is simple, assembly is a little bit advanced or confusing, especially trying to figure out what screws go where. The wires are color coded to the instructions. The gears, and just about everything is color coded to make assembly easier. Make sure you have 5, D-batteries to make this thing operate.
