Vertical farming/gardening systems and methods of using. The systems include a track defining a path in which a change in elevation occurs, buckets pivotally secured to the track to travel along the path, and a moving mechanism for moving the buckets along the path. A first bucket has a cavity containing either a growing medium capable of supporting plants growing within the cavity or a solar collector for dehydrating plants within the cavity. One or more service stations located along the path of the track perform actions on the growing medium or the plants within the cavity of the first bucket as the first bucket travels along the path. One or more sensors analyze the growing medium or plants within the cavity of the first bucket. A master control unit controls the system including travel of the buckets along the path of the track.

The present invention discloses a method and system for switching an operating state of a robot. The method comprises the following steps of: providing an excitation device for an opening terminal and an excitation device for a closing terminal on a mask of the robot; transmitting, by the excitation device, a mask state signal to a slave computer processor when the mask is opened or closed; by the slave computer processor, processing the received mask state signal and then transmitting the processed mask state signal to a master computer processor; and controlling, by the master computer processor, the switchover of the operating state of the robot according to the received processed mask state signal. With regard to the technical solutions of the present invention, through the opening and closing of a mask, the system of a robot can be in two operating states and perform different functions.

A device includes a master device, a set of slave devices and a bus. The master device is configured to transmit first messages carrying a set of operation data message portions indicative of operations for implementation by slave devices of the set of slave devices, and second messages addressed to slave devices in the set of slave devices. The second messages convey identifiers identifying respective ones of the slave devices to which the second messages are addressed requesting respective reactions towards the master device within respective expected reaction intervals. The slave devices are configured to receive the first messages transmitted from the master device, read respective operation data message portions in the set of operation data message portions, implement respective operations as a function of the respective operation data message portions read, and receive the second messages transmitted from the master device.

Disclosed is a master robot for controlling at least one slave robot. The master robot includes a communicator that communicates with the slave robot or a mobile terminal, at least one sensor, an inputter that inputs an image signal or an audio signal, and a controller that creates a space map corresponding to a predetermined space in which the master robot and the slave robot are located on the basis of information sensed by the sensor or information inputted through the inputter. Accordingly, a master robot equipped with artificial intelligence and a 5G communication module can be provided.
