Meet Sentigent Technology’s Rovar X3, the outdoor companion robot showcased at NVIDIA GTC that seems determined to get some fresh air. Unlike its house-bound cousins that live in fear of shag carpeting, this all-terrain, two-wheeled bot is designed to follow you through parks and on trails using its advanced perception to track your every move. It’s being pitched as a hiking buddy and even a “babysitter,” because what child doesn’t want a 15kg rolling chaperone that runs on a six-hour battery?
