droidcon Berlin starts off with a barcamp on Wednesday, followed by two conference days and finally it features a one-day hackathon on June 6, 2015.

The droidcon hackathon is your chance of putting into practice what you have learned at the conference, and maybe form some lasting partnerships by bringing your ideas to life! You’ll be joining forces with other passionate Android developers to create something unique – or even win a prize provided by our hackathon partners. This hack will attract some of the most talented coders and creative experts!

How can you join the hackathon?

Register for a free hackathon ticket by the 29th of May!

Even if you have already bought a ticket for droidcon Berlin, we need a separate registration for the hackathon in order to take care of the catering, program and facilities.

What will we provide?

There will be several challenges that you can work on in groups. Our partners will send amazing projects or gadgets to hack and some of their experts who will explain it and help you in creating something amazing by mentoring you. We'll have SDKs, food, software and coffee.

What are the challenges?

We are happy to introduce you to the first challenge for this year's droidcon hackathon:

"Build and program automotive robots"

In this project, you can build your own automotive robots with LEGO Mindstorms. The Mindstorms system provides not only LEGO bricks, but also different actors and sensors and a programmable brick to create models which illustrate real life use-cases in connected or (semi-)autonomous cars scenarios. At the beginning you can build some simple vehicles using standard building instructions or using your mechanical engineering skills to create the model you need.

After this building phase we will dive into the programming of the vehicles. You can create cars which collect data while driving around and cars which communicate with each other (car2car), with infrastructure (car2x) or with your android device. You can even create vehicles with (semi-)autonomous abilities. Bring any idea from the connected cars world you want to realize and try to bring it to life with the parts provided and in the time frame you have during the hackathon. Beside a lot of building material and printed documentations we will have an expert on site who will give you some individual introduction how to program the robots using Java.

Please check out http://www.lejos.org/ for documentation of the java programming abilities of the mindstorms system in preparation to this hackathon (we will only have EV3 and NXT systems on site). Please bring also your computer with your preferred and ideally prepared programming environment. There's a limited number of spots available for this project, so please come early and sign-up on Saturday.
