The software is composed of a web server and a 2 or more clients. The Raspberry Pi, Arduino, Stepper Motors and Drivers, Battery Emulation Circuit were purchased off Amazon. Don’t forget that the Amazon prices are pretty good, when you factor in Prime’s free shipping. If you buy the parts from Ebay you might be able to save more money. These parts can be purchased from Amazon or Ebay. This section of the blog covers the parts that were purchased online. You will need a larger battery for production.

I am amazed with the availability and low cost of the technology. The objective is to keep the cost down by using Off-the-shelf parts that are available most places such as Lowes, Home Depot or online. Of course, with any project, the budget is limited. At this point, in the project, we are only proving a concept. Mobile Robot and Test Fixture About the robotsĬurrently our robots are prototypes. My friend did most of the heavy lifting on the software. A friend and I built robots which are controlled from a web server and wifi. Software is a significant part of the robot, because it controls everything. I increased my knowledge in web development. Basically you are coupling motors to move to an object to move that object. I discovered building robots uses some of the same skills for building CNC machines. This post is about getting into robotics.
