Project Name : Romanticar

Romanticar is the word that combine with ‘romantic’+’car’. Our project is for a couple who wants to propose. You can surprise your girlfriend with this car. This car also has a special fuction. It can follow a line. Bottom of a box, there is a light recognition sensor. So when you draw a line on the ground, it can follow your line. Also, at the very top of this box can be open. You can put a ring or special gift inside it. When the romanticar arrive to your girlfriend, you can open that box, and give a ring to your girlfriend. Our box design is motivated by the movie ‘The grand budapest hotel’. Mendl’s bakery box was our reference.

We bought a kitty bus for a proto. We tested the sensor recognition.

Conclusion :

I really learned lot from this project. At the final presentation, we failed to follow a line because of a power. First time when we test just with the base, it worked really well. But when we put the box on it, the weight was became heavy. We thought the boxes won’t weigh a lot, but it wasn’t. The motor needed more power. We had to reassemble the gear motor stronger. But it was too late that time. It was really sad, but I learned from this. I have to do a many, many test. I have to be more careful, precise person. Also I learned a new skill from this project! Laser cutting! It was very interesting experience to me, and I hope to use this skill later for my other projects! And the fablab was really great, too! 3D printer work was really impressive!

Thank you for teaching us, Professor Todd!!★
