I'm finishing my thesis in AI, and can handle programming. However, i don't know how to control motors, servomotors and such things. I am interested in doing so, and furthermore, with some of my students (i do some teaching in programming and AI) we want to start some kind of "hacker lab", meaning that we'll be experimenting stuff, and trying to craft devices, and interact with the real world rather than just doing regular programming.
When we discussed about raspberry pi, we all got really enthusiastic. So now, one of my students want to control a RC car with a raspberry pi. My own project is to use servomotors to make a motorized camera, and a third one already ordered his own raspberry pi for goals that i don't know yet.
Tu put it short, we need to be able to control motors and servomotors from the raspberry pi, using the IO ports. I have seen some methods to control a small servomotor directly from the Rpi, but i read that i can't be used for larger servos, and it's limited to only one. So we need help not for the programming part, but the hardware part :
-How can we make a motor/servromotor driver that can be controlled from the Rpi?
-What kind of hardware should we buy in order to realize this, and experiment?
-Could you provide online ressources for beginners for the electronics required for controlling such devices?
I want to stress that we need simple designs, because it has a learning purpose : the goal is to be able to understand the basics, so that each student can adapt it to his/her goals, and is capable of explaining to other students.
We are located in Guadeloupe, a small island in French west Indies, where it is difficult to obtain hardware, so we will be ordering on the internet the electronic parts (probably on RS component when ordering the Rpis).
If some people could also recommend pieces of hardware that are not directly useful for this current task, but has educational interest, and could be used for learning purposes, i'm open to suggestions!
In advance, thanks to all!
