Schematics
Here is a BIG collection of Schematics.
Many thanks to BEAM-online
who , without him, I couldn't have bring you this wonderful page. To
build any of these circuit, you will need to know the pins layout of the
components. Click here to go to the pins
layout page.
All of the
shematics were made with Paint

4 motors
walker >CLICK on the image to see it BIGGER<
• 4 x 74HCT240
• 8 x 0.1uf capacitor ( read note )
• 4 x 2.2M resistor
• 2 x 4.3M resistor
• 1M resistor
• 4 x motors (servos motors)
The value of the capacitors can be different from a robot to a other.
It really depend of the type of motors you use. If you have a low RPM
( Rotation Per Minute ) ( turning slow ), you
need to but bigger value for the capacitors. But in the other hand, if
you have a high RPM ( turning fast ), you need to but
smaller value for the capacitors. You need to EXPERIMENT. It
won't kill you to try different resistors and capacitors value. You
will learn from you experiment.
If you want to put a reverser to the walker, put it where you see the R on the drawing
below.
I think you need to put a H-bridge to control the servos or motors.
Don't forget to check out the Scout
walker 2 from Solarbotics.

The
Microcore >CLICK on the image to see it BIGGER<
• All capacitors value are 0.22uf Bi-polar
• All resistors are 1 MegW
• Power from 3 Volts to 10 Volts

Auto PNC (Process Neutralization Circuit)
• 2 x diode 1N4148
You just add these two diodes to your microcore. When you power the microcore you will achieve the single process state.
