This robot has been built in Lego mindstorms education. After the construction, we have used Lego mindstorms education NXT software to write the behaviour of the program. Calimocho follows the black line, if it detects an obstacle at a distance of 10 centimeters in front of it, Calimocho pass round the object and after come back to the black line.

1. The program starts checking if there is black line, in order to get this parameter we use a light sensor.

2. In order to know if there is an obstacle, we use a ultrasonic sensor. In case of detection the robot pass round the obstacle.

3. After have passed round the obstacle, Calimocho go back to the black line and start again to follow it.
