Abstract: Embodiments herein describe a controller for a machine that wirelessly transmits a destination address to a robot which is tasked with transporting an item to the destination corresponding to the received address. Using the address, the robot can select a predefined path stored in its memory for that address. Because multiple robots can move items in the machine at the same time, the robots may collide if their predefined paths intersect. The machine can use a variety of different techniques to prevent collisions between the robots as the robots deliver items to different locations along their predefined paths.

Abstract: Embodiments herein describe wireless transmission techniques for mitigating interference between wirelessly controlled machines in a shared space. To mitigate interference, the machines may be assigned different channels within the same frequency band. However, if machines using the same channel in a frequency band receive each other's wireless signals, the wireless signals can interfere. To free up additional bandwidth, in one embodiment, the command signals are transmitted using a different frequency band than a heartbeat signal used to stop the machines in case of emergencies. In another embodiment, time multiplexing or directional antennas can be used to mitigate interference. In another example, antenna diversity and multiple-input-multiple output (MIMO) can be used to further focus the radiation pattern onto the desired machine while avoiding transmitting wireless signals to neighboring machines. In one embodiment, the machines may use dual-channels to transmit and receive duplicate data.

Abstract: Embodiments herein describe a system that includes a first Faraday cage defining a first aperture through which a first conveyor extends, a first wirelessly controlled machine disposed in the first Faraday cage, where the first wirelessly controlled machine is configured to transmit control signals using a first frequency range, a second Faraday cage defining a second aperture through which a second conveyor extends, and a second wirelessly controlled machine disposed in the second Faraday cage where the first wirelessly controlled machine is configured to transmit control signals using the first frequency range. Further, a portion of at least one of the first Faraday cage and the second Faraday cage is disposed between the first and second apertures.
