CRS Human-Robot Collaboration & Ergonomics Flashcards

What is the role of a risk assessment before deploying a collaborative robot system?

Answer: Identifying hazards and determining appropriate safety measures for human-robot interaction

A risk assessment identifies all potential hazards in a collaborative application and determines the necessary safety measures to reduce risks to acceptable levels per ISO 12100.

In collaborative robot standards, what is a 'restricted space'?

Answer: The portion of the maximum space limited by physical stops or safety-rated software limits

The restricted space is the portion of the robot's maximum range that is constrained by physical hard stops or safety-rated software position limits to reduce the hazard zone.

What is the primary benefit of force feedback in collaborative robot applications?

Answer: Allowing the robot to detect and respond to unexpected forces for safer and more flexible interaction

Force feedback enables robots to detect unexpected contact or resistance and respond compliantly, protecting both human workers and workpieces during close collaboration.

What does safety light curtain technology do in a semi-collaborative robot cell?

Answer: Create an electrosensitive protective field that stops the robot when the light field is interrupted

Safety light curtains create an invisible array of light beams that immediately stops robot operation when a person's hand or body interrupts the beam pattern at the cell boundary.

What does 'cognitive ergonomics' address in human-robot collaboration design?

Answer: Mental workload, situational awareness, and decision-making demands placed on human operators

Cognitive ergonomics addresses the mental workload, attention demands, and situational awareness requirements imposed on workers who collaborate with robotic systems.

How should a collaborative robot cell be designed to minimize cumulative trauma disorders (CTDs) in workers?

Answer: Design tasks to avoid repetitive awkward postures, excessive force requirements, and prolonged static loading

CTD prevention requires collaborative task design that eliminates repetitive awkward postures, minimizes force requirements, and avoids prolonged static positions that cause cumulative musculoskeletal stress.
