Electrical

In this schematic we see how the electronic components are connected in the system. By pressing the push button, it activates the system by engaging the servo motors. After the servo motors are engaged, the hand begins to unscrew the light bulb. After this the servo motors rotate in the other direction to reverse the process and places the light bulb onto the designated area. Once that task is completed, the arm will then grab the new light bulb and the servo motor's will reactivate to reposition the arm to precisely position the light bulb under the housing. Once it is placed in position, the servo motor attached to the wrist will activate and screw the light bulb into the designated area.
