Robots are going to do many things for us in the future, including delivering our purchases. Take Camello from OTSAW for instance: it is an autonomous mobile robot for last-mile delivery that can be scheduled and tracked on a smartphone. It can be programmed to deliver to designated places without human intervention.
The robot has waterproof compartments that can hold up to 100L. It has a UVC module to disinfect parcels. It uses 360-degree LiDAR, cameras and sonar to get around and avoid obstacles.[more info]
