Step 1: Plan

After the in-class discussion, we decided to make a collective decision project called “Gathering Up”.

Main Procedures: 

1. During the project, keep sending the (x, y) position to the Robotbits.
2. The 5 Robotbits will be spread on the ground.
3. The 5 Microbits will calculate the distances between every 2 Robotbits.
4. Every 2 Robotbits that are close to each other will gather together.
5. The Microbits will calculate the distances between every 2 groups of Robotbits.
6. The most closed 2 groups of Robotbits will gather up.
7. The 5 Robotbits are all clustered.
8. The 5 Microbits display “Robotbits Assemble!!” (and maybe an audio clip).

Materials:

Microbit x 5

Robotbit set x 4 (optional)

Step 3: Reflect on the process

The collective decision is really a challenging topic to address.

It requires many technical skills like the application of openCV and wireless communications between Microbits.

Besides, it needs a whole group of student (for example, we have 5 people in our group) to adjust their schedule to create a perfect time for all of the members to work on the project.

However, the process of making the project is exciting and interesting. 

Most importantly, we learned a lot from this collaboration.
