In the past few months, we have covered plenty of suitcases smart enough to follow their owner autonomously. If you know your Arduino and coding, you can always build your own. Hacker House has shared a guide that shows you how to use an Arduino UNO to make a smart auto follow cooler.
The cooler connects to your smartphone and uses GPS coordinates streamed from your phone to follow you. You are going to need a cooler, 1 x Arduino UNO, battery, 6-inch wheels, 1 x GPS module, and a few other components for this project.
