  "abstract": "Techniques for controlling motion of physical, moving devices within a robotic work cell of an inventory system are disclosed. A user device (e.g., a wearable device) can be used within the workspace to transmit wireless signals. One of these signals can be received by one or more receiving devices associated with the robotic work cell. A proximity monitoring engine can transmit notification data to a machine controller while the signal is being received. Transmitting the notification data may cause the machine controller to execute instructions to halt motion of the robotic device (and/or other moving devices associated with the robotic work cell). The devices of the robotic work cell may remain in a halted state while the signal continues to be received. When the signal is no longer being received, the devices of the robotic work cell may be instructed to resume motion.",
