So I want to make robotics...

Post by Komaru » Sat Aug 04, 2007 3:15 am

As an introduction, I'm 18, just graduated from high school, and am planning to major in Theatre Arts, focusing in Technical. And I want to make robots. I have a vague history with electronics, though mostly just computer work. I used to have the LEGO Mindstorms 1.0 kit, but that's long gone now.

The equipment I have is as follows:

Multiple PIC16F628A Microcontrollers
An unholy amount of electronic equipment
Some small motors
Some drive control chips
Pic Robotics
Various Useful Tools

My knowledge is the real problem as I have a weak grasp of the PICBasic language, and a case of ADHD that makes electrical diagrams a royal pain to deal with.

So right now, I'm just trying to drive the motor, which isn't working, and I'm wondering if y'all know a good place (preferably online) to start with.

Dont know how much background knowledge you have, but some pointers for you.

Look up PWM (pulse width modulation) for speed control.

Also DO NOT drive the motors direct from a PIC, use some sort of buffer or transistor arragement. The switching on/off of motor can serverly damage a PIC.

Also look up H bridges for direction control.

As for the schematics, well you will have get used to them !

Personally I dont like BASIC at all and preffer using Assembly language or C.
