Below is the story of my work developing the initial prototype, ERTE-0.

Introduction

Robotics is a field that I have always been obsessed with. However, I have found it hard to get into. In my experience, affordable robotics kits, such as of the solder-yourself variety, tend to be fairly simplistic and restrictive.

 

For example, If you want a line-follow robot, then you make a robot specific to that function, just as you would buy a particular kit if you wanted a robot to follow the light or navigate a room. Considering that these kits tend to be of low-quality build (lack of wheels, sticky tape instead of brackets and screws, etc....), these robots are only suitable for educational / gimmick use only.

 

The aim of this project is to create an easy-to-follow educational kit, where detailed instructions enable you to start with a basic robot and expand the system with more complicated functionality as you learn more advanced concepts. To start, i believe it be essential to produce a suitable p[latofrm, with wheels, battery case, brackets, and designed to be taken apart many times and expanded. With this suitable platform, a proper foundation for a modular robot will be offered.
 

Goals

Below are the main goals listed:

 

  • Comprised of generic off-the-shelf components

  • Custom PCB's with simple layouts, able to be replicated with prototyping boards

  • PCB's to be well labeled, including component vales, with easily distinguishable traces 

  • Each distinct area (Sensors, Control, Motor Driving...) is to be separate and swappable modules

  • Expansion considerations built-in

  • Cross module compatibility

  • A rigid body designed to be repeatedly taken apart to enable modifications

  • Fully detailed instructions with the design well explained

  • One robot - various possible functions and module combinations

The Investigation
1 - Overview
 

To initiate the repair, we first need to strip down the robot to expose the error, as the basic checks show the fault lies within the robot. Below is a picture of the top face of the robot in question.
