Following the instructions in the kit we build multiple different circuits that would teach us the basics of Arduino. Below are those projects that taught us various lessons. 

After we put together the RedBot using the instructions in its digital manual, we began testing its line-following capabilities. After adjusting the line sensor threshold and running some tests, the bot was able to follow a line and turn as the line turned accordingly. 

Attached to the RedBot is a whisker that bends into a bumper so that the robot knows when an object is near. When the robot detects an object in front of it, it is supposed to turn and go in a different direction. The video on the right showcases this process.

We also created a short virtual simulation of a robot with distance sensors that avoid obstacles in its way by turning and going in a different direction. Attached is a video of that simulation running and the source code of the robot. The code is extremely simple, and just updates the distance value that is taken from the sensors on the robot, and senses when an object is there. Then, when the robot senses that there is an object near, it turns and continues going forward in a new direction where there are no objects in the way.

In order to create our final robot that utilizes an ultrasonic sensor to detect objects and come up with feasible and safe paths to travel. To the left is a picture of the robot at the end of its design process.

To the right is a video of the finished robot Tamiya that uses its sensor to detect objects and move around. We had some issues with the belt so we had to remove the bottom wheels, but other than that it can still move around pretty effectively.
