CRS Human-Robot Collaboration & Ergonomics Flashcards

What is 'hand guiding' mode in collaborative robotics?

Answer: Directly guiding the robot arm by hand to teach positions or paths

Hand guiding allows operators to physically move the robot arm by hand to intuitively teach new positions or paths, typically using a handle with an enabling device near the end effector.

What is the purpose of a 'safety-rated monitored stop' in collaborative robotics?

Answer: Halting robot motion when a human enters the workspace and automatically resuming when they safely exit

A safety-rated monitored stop halts robot motion when a human enters the collaborative workspace and automatically resumes operation when the human safely exits, without requiring manual restart.

What ergonomic principle should guide the working height of a collaborative robot workstation for standing operators?

Answer: Approximately the elbow height of a standing worker to minimize reaching and back strain

Workstations should be designed at approximately the operator's elbow height to minimize overhead reaching and bending, reducing back and shoulder strain during collaborative tasks.

How does end-of-arm tooling (EOAT) design impact human-robot collaboration safety?

Answer: Rounded, padded, or compliant EOAT reduces injury severity during accidental contact

EOAT designed with rounded edges, soft materials, or compliant features significantly reduces the severity of injury in case of accidental contact between the tool and a worker.

What is the role of vision systems in a human-robot collaborative cell?

Answer: Detecting and tracking human presence to enable dynamic safety responses

Vision systems detect and track human presence in the robot's workspace, enabling dynamic adjustments to robot speed and path planning to maintain safe separation distances.

What does 'task allocation' mean in a human-robot collaborative workflow?

Answer: Determining which tasks are performed by the robot versus the human based on each party's strengths

Task allocation divides work between humans and robots based on their complementary strengths, with robots handling repetitive or physically demanding tasks and humans handling judgment-intensive work.
