Abstract
Techniques for performing automated device activation and managing access to a workspace are described herein. While operating in an activated state, a user device (e.g., a wearable device) may be configured to modify movements of various mobile components (e.g., mobile drive units, robotic arms, etc.) of the workspace by emitting signals that cause the mobile components to stop or reduce speed when in proximity of the user device. An access controller device (ACD) may be used to restrict and/or allow access to the workspace and to perform operations for activating a user device that is attempting access. The ACD may receive light emissions from the user device that may be used to initiate a process for activating the user device. When the ACD receives an indication that the user device is operating in the activated state, the ACD may execute operations for enabling access to the workspace.
