The comparator circuit was controlled through a photo resistor. Depending on the amount of light hitting the photo resistor the state would be either high or low. A relay set up as an H-Bridge would transfer high and low two forward or backward movement of the motors. | The comparator circuit was controlled through a photo resistor.

Originally we wanted to mirror this circuit on the breadboard so both motors could be controlled independently. Unfortunately we were missing a second Transistor (TIP-127) to be able to finalize our plans that weekend. | Originally we wanted to mirror this circuit on the breadboard so both motors could be controlled independently.

Although not being able to complete our second assignment to the extend we had originally imagined, we somehow had the feeling our vehicle was developing it's own character in a way. | Although not being able to complete our second assignment to the extend we had originally imagined, we somehow had the feeling our vehicle was developing it's own character in a way. | ||

For our third assignment, instead of starting from scratch – we decided to continue working on our vehicle as we had become quite fond of it. | |||
The main question was; what could this vehicle do? | |||
The answer came quickly. With a pen or felt tip attached it could become a simple drawing machine. | |||
Whilst making the vehicle its self more sturdy with a metal framing – concidering the cricuit we took a step back. Instead of it being reactive to light through the comparator it was controlled by two 555 timers. Now each motor could act independently. With it not being reactive we could analyze the patterns better that it would produce. The patterns depend on the timing of the ICs and therefor could be altered by changing the resistors and capacitors on the breadboard. | |||
In a further step we are considering combining the Assignments 2&3. | |||
the drawing machine could become reactive again. Ideally it would still produce recognizable patterns, but vary these once the lighting situation changes. | |||
Also finding a different drawing tool, so the vehicle doesn't have to be limited to a sheet of paper would be something to take into account. | |||
