Robotic cells

A robot cell, comprising:

• a cell floor defining an array of nodes corresponding with a predetermined two-dimensional coordinate system and defining a volume for receiving a workpiece therein;
• a set of robots, including a first robot, each of the robots of the set of robots having a respective base, end effector and working envelope and defining a respective three-dimensional coordinate system, located according to the array of nodes;
• a set of detectors, including a first detector, each of the detectors of the set of detectors being configured to detect a location and/or bearing of a respective robot of the set of robots using a set of targets disposed on and/or in the cell floor;
• and
• a controller, communicatively coupled to the set of robots and to the set of detectors, the controller being configured to control movement of the set of robots using the detected respective locations and/or bearings of the set of robots.
