A system for picking and packing applications is provided. The system includes a plurality of robots and a plurality of robot controllers. Each robot controller includes a load re-balance subsystem, a load balance subsystem, a robot state change detector subsystem, a communicator subsystem, and a motion control subsystem. Each of the robot controllers is interconnected and in communication with one another via the communicator subsystems. Each of the robots has a workload that may be selectively balanced. A method for balancing the workloads of the robots using built-in processors which run motion control is also provided.
