[0002] Currently, robots have been widely used to move between different floors of a building to carry goods. Robot taking the elevator, if mixed with passengers, may reduce the passenger's elevator experience, and the research focus of the prior art is mainly how to reduce the impact of robots on passengers taking the elevator. In fact, the greatest impact of robots on passenger elevator experience is to share the elevator carrying capacity originally used to transport passengers (especially the increasing demand for robot delivery, such as delivery robots in hotels).
