SwARM last update of the week-end before evalutation

Hui everyone,

This week-end we worked hard to finish our project. We are near the end still there are things more to do.
I soldered three more boards and manufactured leds strip with Arnaud.

We are merging moving branch with the choreography algorithm.

that’s all. 🙂

SwARM much to say

So this week we debugged motors with Paul then with Arnaud with oscilloscope.

We founded that the H bridges have a strange behaviour. More in the next episode.
Here the signal on the motor.

I also crafted all the motors with coding wheels during the week end.

I also have found why the usb don’t work. The two pist pm dm have been inverted.

So Arnaud patched his board

That’s all have a good night.
sorry for the delay.

It Works but it Broke

Hi everyone,

so I finally founded and managed to port some MPU driver to ChibiOS. It’s very cool because it include fusion algorithms (Mahony Quaternion Update ), calibration and self test and…
It’s a Beerware (I love those) !! ^^
So I have values but they are floats and I need int to print them correctly with ChibiOS on serial (that’s just a detail). So I tested my program and it worked but I moved the IMU so many times to test the driver that I broke some wires >< I will repair them tomorrow morning before class.

I also started to write the board.h for our board. It will be finished this week. All pins have been defined and named. I just have to specify the modes of each pin.

Now let’s talk about the choreographies :
When the project started we would like to work on emerging behaviour but it seems complicated to work on that if we d’ont have any fonctionning bot.
So it seems more reasonnable to describe some preset choreagraphies that our bots would do.
We would like to do some circles and one sort of horizontal multi-colour 8. Then we could do one little party of pong.
So we need that our bots can do curve and strait lines because they will recieve orders every 10th of seconds at least. 🙂

that’s all for tonight.
