Turning a remote controlled car into a tank using Arduino. via instructables
I have always been fascinated by big machines, tanks in particular. The German Tiger Tank, as featured in the movie Fury!, is an awesome machine. I wanted one! I did some searching and found that RC Tiger Tank replicas cost over $150, and they do not do 360 degree turret rotation (at that price level). So, I built my own version. I had previously built a tank out of cardboard (video here: https://www.youtube.com/watch?v=6pNfTbsYIGQ, in my youtube channel – see my other videos while there) with wired remote control. That tank was inspired by a combination of ideas from Matthias Wandel’s Wooden tank thread vehicle (https://www.youtube.com/watch?v=buuaxdUYNb8) and Eliseo Benavides’ work with cardboard gears (https://www.youtube.com/watch?v=QB9xhZntN5Q). My main idea was to build a functional RC tank at a minimum cost. It took a lot of thought, design decision making, debugging hardware and software, trial and error, etc and having fun at the same time. In particular, transferring power to the rotating turret to make it free rotating was, ahem, challenging and inspirational, given my budget constraints. The final product is by all means still a prototype, but I am very proud of it. I learned a lot of lessons from this projects, including Tx/Rx signals, Arduino shield construction, H-bridges, and coding my first C program.
