As a Las Vegas native who enjoys watching boxing and has always cursed the exorbitant cost of entry to fights at the MGM Grand, when an invitation to a CES event at Top Rank Boxing Gym appeared in my email inbox, I immediately RSVPed. Top Rank is a legendary boxing promoter, and its gym is where some of the greatest fighters have trained. So I went to the gym after a day of canned press conferences from the world's biggest tech companies to see featherweight Francisco Esparza, a local champion, throw punches in the ring. Esparza was demonstrating a new wearable device from French startup Piq Sport Intelligence, who partnered with 100-year-old boxing gear maker Everlast to develop what it calls Robot Blue. Piq's Robot Blue is a sensor-packed nanocomputer that a boxer or mixed-martial arts fighter slips into a wrap, which is then placed around the hand or the top of the glove.
