Servo Controller: A thought experiment

First up, this is at best a work in progress, at worst only ramblings.

I have seen members asking about driving more than a handful of servos and getting the response that they can either use an arduino and its assorted libraries to drive 12+ servos, correction, up to 20 servos or get a dedicated controller board that seems to cost in the area of 50USD. I spent an hour or so knocking up an idea. I want to lay out my thoughts and see where it could or should go.

Sensor seeking.

Let's Make Robots! Hello LMRians! I ordered some parts and i order more in few weeks.

I want to do my own sensor using LDR,IR led and normal leds. And yes, it's going to be something like AmandaLDR but not exactly same.

The sensor is going to my mini sumo, project what i'm working for. It's using Picaxe-08M. What do you think about it?

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.
