Our robot has been built with Lego® Mindstorms Ev3 pieces. Its form is because we wanted to make as much missions as possible in the less time we could, reducing the time that we return to the.

 

We have a right-angled form with little wheels on the right and left side because like this the robot can follow the wall with a lot of precision and without using tactile sensors on the sides. Sparrow has two types of sensores. Two color sensor to follow the lines easily and two touch sensors at the back of it because it loses the accumulated error.
