Week 3: Electrical Design and Materials

For this week, our team focused on the electrical design of our animatronic. This is crucial because our servo motors and DC motors need proper wiring and an electrical source to work.

Objectives:

• Electrical Design of Animatronic
• Shopping List
• Motor Testing

Our main objective, is to sketch the electrical design, shown in Figures 1, 2.

Shopping List:

• Skeleton body
• Raspberry Pi module
• 2 Servo Motors
• 1 DC Motor
• AA Batteries
• 9V Batteries

We tested the motors with the batteries to see which ones were compatible with each respective motor. We found that we needed a 9V battery for the DC motor and two AA batteries for the servo motors. Here is a sketch of the 9V battery and DC motor, shown in Figure 3.
