This project is solving the Lego Rovers challenge.
In our approach of this challenge, we wanted to keep the application as simple as possible, so that every children can enjoy manipulating the rover, without having to learn complex interface.
In order to provide a solution to this project, we will concentrate on the WIFI (It will enable futur support in EV3, the new mindstorms system), and create a webserver app to bring tasks interaction and mobile devices connectivity to life. We will use genuine LEGO sensors , to ensure direct usability in a classroom. starting from retail/educational kit from LEGO, we make use of:
- Ultrasound for obstacle avoidance with user threshold,
- Light/Color for environment condition detection and interaction,
- Touch sensor for soil/samples test.
We will provide an application already compiled (plus the NXC sources and docs, of course!), thus teachers/parents just have to download it to the NXT and the NXT2WIFI, with USB... No more Java involved! We will use the "enhanced" firmware, which is retro-compatible with NXT-G, to ensure easy setup, and keep operations as simple as possible!!! We will provide pedagogical resources, focused on MARS rover.
We will build in a second time, an odometry framework, to implement a "return to base", and "goto place of interess in x,y coordinates" behaviours. In a third time, we are considering to add an interface to the data flowing from Mars, establishing a connection to the other challenge involving Mars Rover, "curiosity-at-home", as a team member as worked on the same base for "We Are Curios", aka LEGO Mindstorms Rover. It would be fun for students to see the "real tracks" directly!!!
The EV3, third LEGO Mindstorms Kit generation, will be able to run the NXTSpaceApps program. The Bricxcc will be ported with the EV3, and the WIFI dongle will allow wireless network connection.
