„Reduce to the Max“:
• Focus intelligence on the robot (sensing, control)
• Use of human capabilities(Sensing, decision, …)
• Sharing of manual workplace resources

Human-RobotCooperation?
What about these workplaces?
Robot requirements:
• Symbiotic human-worker cooperation
• Robust bin picking
• Multiple assemblyprocess control
• Machine optimization and learning skills
• Operation of manualprocess equipment
• Low-cost
• Fast change-over
• Displaceable
