CRS Human-Robot Collaboration & Ergonomics Flashcards

What is a collaborative robot (cobot) specifically designed to do?

Answer: Work safely alongside humans without traditional safety barriers

Collaborative robots are designed to work safely in shared workspaces with humans without requiring traditional hard guarding or safety fences, enabling direct human-robot teamwork.

Which ISO technical specification specifically governs safety requirements for collaborative robot systems?

Answer: ISO/TS 15066

ISO/TS 15066 provides specific safety requirements and guidelines for collaborative robot systems, supplementing the robot safety standards ISO 10218-1 and ISO 10218-2.

What is 'power and force limiting' (PFL) in collaborative robotics?

Answer: A safety mode where the robot stops when contact forces exceed a safe threshold

Power and force limiting is a collaborative operation mode where the robot continuously monitors contact forces and stops immediately if they exceed safe human pain/injury thresholds.

What does 'speed and separation monitoring' (SSM) mean in collaborative robotics?

Answer: Dynamically adjusting robot speed based on measured distance between the robot and humans

Speed and separation monitoring dynamically adjusts robot speed based on the real-time measured distance from a human, slowing or stopping as a person approaches the robot.

What must be factored into safe stopping distance calculations for a collaborative workspace?

Answer: The total distance the robot travels from human detection to full stop

The stopping distance is the distance the robot travels from the moment a human is detected until the robot fully stops, and it must be calculated to ensure the human cannot be reached before the robot stops.

In human-robot collaboration ergonomics, what is the primary design concern for object handover tasks?

Answer: Ensuring safe, comfortable transfer without awkward postures or pinch points

Handover task design focuses on presenting objects at ergonomically comfortable heights and orientations that prevent awkward postures and eliminate pinch point hazards.
