Meet Sentigent Technology’s Rovar X3, the outdoor companion robot unveiled at NVIDIA GTC that looks remarkably keen to swap the lab for the Great Outdoors. Unlike its house-bound cousins that treat a deep-pile carpet like an impassable swamp, this all-terrain, two-wheeled bot is engineered to shadow your every step through parks and along woodland trails. Using a sophisticated perception suite to keep its digital eyes on you, it’s being pitched as a hiking sidekick and even a high-tech ‘childminder’—because what kid wouldn’t want a 15kg rolling chaperone with a six-hour battery life supervising their adventures?
