This is part 1 of a series of articles on my experiences building a robot that can do various things. I thought it would be neat to create a robot that was easy to put together with a single soldering iron and was also affordable. I made up the following requirements for my robot:

  1. Many kits are expensive, so it must be relatively inexpensive.
  2. It must be easily put together without special equipment.
  3. It must be easily programmable without a complicated IDE or programmer.
  4. It must be powerful enough for expandability.
  5. It should run off a simple power source.
  6. It should be able to follow a line or a wall, and avoid obstacles.

In this article I'll talk about how I decided to meet these requirements.
