In the long human effort to close the last gap between warehouse and doorstep, Robot.com has introduced R-dog — a four-legged machine that climbs what wheels cannot. Unveiled in August 2026 and bound for college campuses in 2027, R-dog carries packages and paid advertisements simultaneously, weaving commerce and mobility into a single walking form. It is a small but telling moment in the larger story of how cities, economies, and public spaces are being quietly renegotiated by autonomous machines.
