1st day

C3PO=Molly

First of all, Antton and Maren introduced themselves and they explained to the class what the project was about. We formed several groups and we looked for a pseudonym. Finally we decided to name our group C3PO. They told us to start to build the robot and after we had finished doing it, we started to program it. We created some programs and a circuit. We started the blog and we designed a logo. In the afternoon, we started with the activities which were related to the film and with the Scratch.

This is a program 

2nd day

Firstly the instructors gave us a new circuit which consisted of three different types of curves. Secondly we made a lift arm which we modified twice because it was too short to drag the boxes that we had built before. The second circuit was supposed to be able to drag five boxes, but it just dragged three of them. We changed the arm into a simple one and we started "bowling". After two attempts, we finally succeeded and we threw 3 bowling pins. At the end of the morning we went to the computer science class and we continued with the activities related to the film and we also wrote the day´s blog.

3rd day

On the 3rd day, we went on with the bowling practice. In fact, we spent most of the morning improving it. Then we tried to make it work and we were successful. Later, they explained to us how to play with the bowling pins using a touch sensor instead of the program that we had previously established. We had to press a button and depending on the button that you had pushed the robot did one thing or another. After break time, they explained another type of sensor called the light sensor to us. We tried different methods in order for the robot to stop. If the robot saw the black or the white color it would stop after programming it of course. Besides we wrote the day blog and we did some film activities.

4th day

In the morning we started programming “Molly” in order for it to be able to follow a line which gets thinner and thinner with the help of a light sensor. We had to program it twice. In the first attempt we programmed it to follow the line and come back without stopping and in the second attempt we programmed it like the first time, but it had to stop at the end of the line which was very thin. After finishing this circuit, we built an infrared sensor and we operated a circuit which contained boxes. The third program was about chasing out four cans. We did three different activities and after finishing those activities we started looking for a strategy for Friday’s fight. We wrote the day blog and each of us developed their own Scratch.

5th day

On the last day we started programming Molly and we spent a long time improving it for the fight. Although our structure wasn’t the best one, our program was good so we could win the final. But we didn’t get any points because we had put our lift arm, that didn’t move, in the wrong position so the robot stopped every time we tried to make it work. In the first fight we lost but in the second one we won a game. We had an hour left to finish the blog and continue with the Scratch. In the last hour we organized a party. The project was over. We had fun doing this project and our instructors (Antton and Maren) were very helpful.
