Homemade knex robotics building system project
« on: December 10, 2017, 02:59:50 pm »
Hi everyone, recently I found an old topic wich speak about the "robotics building system education set".
And it was said that the price of the set is too expensive for what it's contain, and that it will be cool to made an homemade robotics building system with arduino or rasberry pi.
It give me some ideas and recently an occasion to do this is appeared at school, in the Informatical and Digital Creation lesson.
 Our teachers said that we can made our own group project, and I proposed you know what. In my group we are only 2, but my teammate is the best programmer of our classroom, so the Knex Robotics Building System project has begin  (- :
Here the first images of the electronical scematics, and of what we need in the algorithm (in french, because I’m french, and because i’m too lasy to translate 2 pages in english for the moment^^)

This looks pretty promising!
Don't forget that a motor can draw several mA's... if drawn directly from your microchip, the chip will not like that! Best if you switch the motor on/off with a transistor. Speed you can regulate with PWM (Pulse Width Modulation). The Arduino has this on several outputs.
This appears to be a signature

Yes I know it, I'll use an H-bridge, because I can control the direction of the motor with it.
Thanks for your advice^^, even though I knew it already.

I've begin the coding phase 2 weeks ago, and... it's very long.....
First coding program, and the whole electronical schematics circuit coming in... I think 3 weeks
And this time I will translate in english ^^
