Utilized PID controllers where the error is the difference in voltage across the two photoresistors
I. e moves left when there is more light on the left, and vice versa
Dual Motors to allow change of direction by turning off one or the other
Implemented C++ control and logic on an Arduino Uno board
Used breadboard to wire circuits for LCD, sensors , and power supply
Used SOLIDWORKS to synthesize a baggage area for the robot allowing for motorized closure and opening
Used soldering skills to assemble electrical components

Some of the motors we received had faulty wire connections, necessitating soldering to attach wires
There was limited space on our given robot chassis, meaning we needed to incorporate three different circuits on half of a breadboard. We needed to fully understand circuit wiring connections in order to design alternate, more optimal configurations that take up less space on the breadboard. We also needed to design the structural configuration of the robot that takes up the least space.
The Uno Arduino did not contain enough digital output ports for us to include the additional motor to control the container
The LCD Display needed many wiring connections to function on top of our already complicated breadboard

Being able to differentiate between digital and analog output
The importance of creating a circuit diagram prior to assembly
PWN 0 & 1 are used for uploading the sketch onto the board but can be used after the fact
