Engineer Creates Arduino-Powered Car That Can Follow Its Owner

Living proof is this human-following robot/car that was build by the YouTuber over at DIY Builder, which relies on an Arduino Uno as the brain of the device.

The video that you can find embedded below also includes all the necessary steps to build the same thing on your own, only that you’ll also have to purchase the required parts from the Internet. In addition to the Arduino, you’ll need the four wheels, batteries, infrared and ultrasonic sensors, jumper wires, a DC power switch, and several motor parts.

The YouTuber has also shared the code and the circuit diagram, so technically, you can just follow the instructions in the video to build your own car.

It goes without saying this thing isn’t a job for the Average Joe, especially given how many parts are involved. The batteries, for example, can be found online for about $15, while the servo motor that powers the car is available for approximately $3. All these components then need to be connected to each other to put the car in motion using the code that is powered by the Arduino board.

The Arduino version that’s being used for this project is the Uno, which is currently available from the official store for just $23 – cheaper ones can basically be found online on the likes of eBay. Technically, you should be able to do the whole thing with any Arduino, including the Nano, which also costs approximately $20.

And of course, just like all the other Arduino projects, this one can be further tweaked with your own code for even more unique capabilities in addition to the ones that are demonstrated in the video here.
