As of now, all parts for the differential have been printed multiple times and reinforced each time. We added shaft holders which we will screw to the Car body. As the Carbody we are using a wooden plank which is not heavy. During the course, we decided to redesign the Driving shaft. We shortened the shaft and we will use a different motor which is bigger and produces more torque.

This is the current state of the differential gear on the wooden body. Our next goal is to screw the shaft holders on the board.

We also started our attempt to use the line sensors with Arduino.

We have created this circuit and a code that does not work yet. We will have to tweak it .
