Proximity detection in assembly environments having machinery

A non-transitory computer readable medium embodying programmed instructions which, when executed by a processor, are operable for performing a method for reporting proximity in an assembly environment, the method comprising:

• inserting an arm of a bracket into an interior of a part that is held by a cradle, and that is worked upon by a robot;
• placing indexing features at the bracket into contact with indexing features of the cradle;
• operating sensors at the bracket to directly detect a location of a first proximity detector worn by a technician and a location of a second proximity detector at the robot;
• and
• directing the first proximity detector to provide a warning to the technician if a distance between the first proximity detector and the second proximity detector is less than a threshold.

A system for proximity reporting in an assembly environment, the system comprising:

• a first proximity detector that is wearable;
• a second proximity detector that is disposed at a robot in a cell of the assembly environment;
• a cradle that holds a part having an interior, the cradle including indexing features;
• and
• a bracket comprising:
• a base having indexing features that mate with the indexing features of the cradle;
• an arm inserted into the interior of the part;
• and
• multiple sensors disposed at the arm.
