Never, ever needed something more. Lugging a cooler full of cold beerĀ sucks, especially during the summer. But the geniuses over at Hacker House created an āautonomous āfollow meā cooler that connects to a smartphone via Bluetooth and uses GPS to navigate.ā In other words, a cooler on wheels! A robot cooler! Itās easily the most Brotastic invention of the summer.

Hereās the bummer ā You canāt just buy it. You have to build your cooler caddyĀ for yourself. Fortunately the folks over at Hacker House have a step-by-step guide, so put that expensiveĀ Yeti you bought last summer on wheels already!
