Designing

First, I Created A Rough 3D Model Of My Robot. 
The original design of the robot consists of a white trash can with a white bowl on top so that it could look like R2-D2. The Arduino board is easily accessible from under the lid so that you can edit/change the circuit and reprogram the robot.

After Some Practice Programming, I Started Working On Some Of The Final Circuit Designs.
Here are some of the earlier final circuit designs that I worked on. I ended up sort of combining the two and I added/subtracted certain sensors and components. Please note that the circuit designs do not include the battery, motors, or 8 channel relay. I also didn't add the Liquid Crystal Display to the design either, however I added a note about it.
