General Information
• LMS is involved in a number of research projects funded by the CEU and European industrial partners. Particular emphasis is given to the co-operation with the European industry as well as a number of "hi-tech" firms.
• LMS employs approximately 70 researchers organized in three different groups:
– Manufacturing Processes and Energy Efficiency
– Robots, Automation and Virtual Reality in Manufacturing
– Production Systems Planning, Control and Networking

Cooperating robots for assembly
•Cooperating robots, are attractive for
• reducing the number of required fixtures
• shortening the process cycle time,
• whilst addressing the accessibility constraints introduced by the use of fixtures
•Their control is based either on the use of
• single controllers, capable of multi-tasking and controlling multiple robots or
• special frameworks, allowing standard controllers to cooperate with each other, by exchanging motion data, as well as synchronization and safety signals.

Cooperating robots performing spot welding on automotive parts
•An illustrative example
•Two robots
•One is picking up and holding the parts to be welded,
•the second performs the spot welding operation.

Challenges
• But....
• The control of cooperating robots should be more intelligently accomplished
• ICT infrastructure is required for managing the complexity of cooperation
• Achieving the required tolerances require use of sensors

Cooperating robots challenges
•Coordination, sequencing, collision and communication architectures.
•Real time motion coordination and communication between robot controllers requires higher computational capabilities from the robot controller side as well as protocols for high speed signal exchange.
•The programming aspects of such systems are characterized by higher complexity since programmers need to consider the dynamic nature of real time communication between robots during the generation of code for the control of the robots.
