This is the wiki page for the Self-Guided RC car that TP is working on.

Overview

Background

This project is a continuation of my Self-Guided RC Car and Self-Guided RC Car AI projects, but enough [has changed / is changing] that I felt it deserved a new page.

The idea is to:

  • Build a RC car that controls itself, and
  • Have that RC car figure out HOW to control itself on its own, using some sort of adaptive learning routine.

The car's intristic goal will be to always be rolling.

Vehicle

"Standard issue cheap piece of junk from Radio Shack."

The car has two simple brushed DC motors. Rear drive motor has High/Low gear box with manual selector; steering assembly is spring-loaded to return to center when steering motor is not powered. Chassis came with a rechargable 9.6 battery and an on/off switch. I added the oversized terminal strip.

Wire Purpose
Red Positive Lead from Battery
Black Ground from Battery to On/Off switch
Grey (thick) Ground from On/Off switch
Yellow Rear Motor Lead A
Green Rear Motor Lead B
Brown Steering Motor Lead A
Grey (thin) Steering Motor Lead B

Control

The following will be fleshed out later.

Controller

PIC

Motor Drivers

H-Bridge ICs

Infrared Sensor

Sharp range finder mounted on a servo

Adaptive Learning

Simplied neural network routine

Current Status - Late Planning

All forseeably needed parts are on hand.

Work Log

No actual, ahem, "work", has been done yet, but a lot of contemplation has certainly been going on.

Current Issues

  • No actual work has been done yet.

Next Steps
