The SMErobotics Consortium has produced a Project Video to explain its vision & mission, its main research and development topics as well as its four main demonstrators. Each of the four demonstrators is displayed in a demonstrator video explaining the workflow of a robotic system in a real-world SME-environment.
The following chapter by chapter description of the Demonstrator D1 video showcases the workflow of "Assembly with dual-arm industrial manipulators".

[Overview over the work piece, the smart dual-arm robot and its working environment]
"In small and mid-size companies of the future, humans and robots will work together in close proximity, with numerous processes being automated through the intelligent use of new robotised solutions. Repetitive and complex tasks, such as assembly processes, will be managed using intuitive methods."

"Safety sensors, in combination with situational awareness, will enable the robot to work with the human operator in a fenceless environment."
[The worker uses hand gestures to start the robot]
"Simple gestures may provide a common language for human-robot communication, such as commands for starting and stopping a motion."
"The introduction of sensor-based cognitive skills will allow intuitive collaboration and robust task execution."

[Easy programming on a tablet computer via an intuitive user interface: The worker selects the task "Gear Box Assembly" and immediatly the robot corresponds with an error message concerning a required tool change.]
"The operator will be able to work with the robot without needing any special knowledge of programming, automation or robotics."
"The smart dual-arm robot will cooperate with a human to accomplish tasks and activities that would otherwise be unergonomic or stressful for the worker."
"Cognitive functions will support collaboration between human and robot in the various phases of each task. This will include both program generation and program execution."

[Compliant robot arms transfer a table with the arranged work pieces for a "Gear Box" into their work area. A vision system scans the objects on this table to identify the parts.]
"Using a sensor-based vision system, the dual-arm robot will be able to recognise and localise objects in its workspace without the need for special fixtures or predetermined object positions."
[The vision system can not identify all parts in the work area. To handle this uncertainty, the robot gives the worker possible solutions, such as manually defining the unknown parts]
"An automated planning system for assembly tasks with sequence constraints will generate the motions to be executed by the robot.
For program generation, the worker can show the robot where the parts are placed. Also, different skills can be combined for more complex tasks."

[A CAD-based 3D preview of the robots motion for the task to be executed is shown on the tablet.]
"A preview of the process to be executed by the robot in the SME-compatible work cell will give the operator an opportunity to make a preliminary evaluation with possible adjustments."

[The two robot arms interact very precisely during "Gear Box Assembly", while the worker supervises the process.]
"Once instructed, the robot will execute the task automatically. A combination of internal motion control and skill execution engine with sensor-based process monitoring will enable the robot to adapt its motions and actions to cope with uncertainties in initial object placement or with inaccuracies resulting from object handling. This will allow the robot to perform complex tasks without the need for complex programming."
"The smart dual-arm robot will provide several common subtasks for use in complex assembly processes."
"Skills such as grasping with cooperative motion or peg-in-hole insertion will be readily available for process planning and manual process instruction."
"In addition, the robot will be able to learn, adapting to exceptions and memorizing manually instructed recovery strategies."
"Object recognition with a vision system and sensor-based skill execution will allow robust assembly processes in an open workspace."
"Safety sensors will permit a fenceless environment in which the operator has easy access to the process as it happens."

[The final step of the "Gear Box Assembly" is to srew the parts together. A screwdriver becomes attached to the toolbox of one robot arm to execute the final step.]
"The robot is equipped with a tool changer, grippers and nutrunners. With tool changes already part of the program, the smart dual-arm robot will offer excellent flexibility together with high precision, enabling it to be adapted for a wide range of tasks and applications."

Original statement (Italian):
Worker: "Questo sistema è straordinario in quanto offre un incredibile flessibilità e varietà di applicazioni. E’ un sistema aperto ed essendo compatibile con Ros e con Linux è facile da usare sia in termine di programmazione che di integrazione con qualsiasi tipo di hardware come sensori pinze o quant’altro. L’architettura aperta ed insieme la programmazione intuitiva aprono il sistema verso una nuova e ampia gamma di applicazioni."
Worker: "The smart dual-arm robot offers high flexibility and versatility. This is an open system, ROS- and Linux-compliant, easy to use with simple programming and integration as well as a wide array of hardware devices: sensors such as cameras and Kinect as well as tools like grippers and screwdrivers. Its open architecture and intuitive programming make the system suitable for a new and wide range of applications."

[The worker picks up the assembled "Gear Box" and does a quality check]
"Over the next few years, robotics will find its way into all fields of human activity. That’s why robotic systems need to be ever easier to use and ever more flexible to allow simple interaction with humans. In other words: in future, robots and humans will work together on every process in every enterprise."
