CES delivers some real winners each year, but it also has a rich history as a breeding ground for weird technologies. In years past, the show has yielded peculiarities such as cell phone radiation-blocking underwear, a waistline-monitoring smart belt, and a vending machine for fresh loaves of bread. It's hard to forget Charmin's 2020 RollBot, a robot that can bring you a spare roll of toilet paper when you run out (strangely foreshadowing the great TP shortage that came just months later). Despite being all-digital this year due to the coronavirus, CES 2021 offered no shortage of oddities. On the list of strange new innovations is a poop-analyzing toilet that offers dietary advice, smart perfume you can customize from an app, and a headless robotic pet meant to soothe your angst. And it only gets weirder from there.
