Delivery robots are small, autonomous machines designed to transport goods from one location to another. They are often used by companies like Amazon and Starship Technologies to deliver food, groceries, and packages directly to customers' doorsteps. These robots navigate sidewalks and streets using sensors and cameras, allowing them to avoid obstacles and reach their destinations safely. Typically, delivery robots can carry a limited amount of weight, usually around 20 pounds, and operate within a specific radius. They are programmed to follow traffic rules and can communicate with pedestrians and vehicles. As technology advances, the use of delivery robots is expected to grow, making local deliveries more efficient.
