A robot includes a secure storage area, a camera, a propulsion system, a memory device, and a processor. The processor is configured to receive a request for drop box services within a casino, the request including a pickup location and a requestor, control the propulsion system to navigate the robot to the pickup location within the casino, and authenticate an identity of the requestor in response to arriving at the pickup location. The processor is also configured to provide the requestor access to the secure storage area in response to authenticating the identity of the requestor, detect receipt, from the requestor, of at least one value instrument within the secure storage area, lock the secure storage area, and provide a receipt to the requestor in response to receiving the at least one value instrument within the secure storage area.
