Parking robot safety device and method

A system comprising:

• a parking robot configured to provide an unmanned parking service by moving one or more vehicles within a designated work area;
• a boundary sensor disposed in a boundary area separating the designated work area from an external area, wherein the boundary sensor is configured to detect an entry of an entity from the external area into the designated work area or an exit of the entity from the designated work area to the external area;
• a monitoring sensor disposed in the designated work area and configured to monitor the entity in the designated work area;
• and
• one or more processors communicatively coupled, via a network, to the parking robot, the boundary sensor, and the monitoring sensor, wherein the one or more processors are configured to:
• determine, via at least one of the boundary sensor or the monitoring sensor, entry of the entity into a staging area that is within the designated work area and is adjacent to the boundary area;
• determine, via the monitoring sensor and based on the entry of the entity into the staging area, an operation characteristic of the entity, wherein the operation characteristic comprises at least one of:
• a speed of the entity,
• a size of the entity, or
• a moving pattern of the entity;
• based on the operation characteristic of the entity, a position of the parking robot, and a moving path of the parking robot, determine a risk level indicating a likelihood of collision, within the designated work area, between the parking robot and the entity;
• and
• control, based on the risk level, an operation of the parking robot to avoid the parking robot and the entity from being located simultaneously in the staging area.
