The electrical component of my mechanism was quite simple. My mechanism had an MG995 servo motor controlling the arm and an SG90 micro-servo motor controlling the claw. They were powered by a single 9 volt battery and controlled using an Arduino Uno and a breadboard. Figure 8 below shows a diagram of the electronic component of my mechanism and Figure 9 displays the electronics implemented in my mechanism.

The code I used to control the arm and claw's movement was done in the Arduino IDE and can be found in the Appendix tab.
