A traditional industrial robot welding car frames operates at 2 m/s with 150 kg payload. An engineer proposes replacing the safety fence with a cobot so humans can work in the same space. Why is directly substituting a cobot for this task problematic?

Cobots are too expensive for any automotive manufacturing application ISO/TS 15066 requires cobots to limit speed and force for human safety, which would make the cobot far too slow and weak to handle the 150 kg welding task at production speed Cobots cannot be programmed to perform welding operations Traditional robots are always safer than cobots because they are physically stronger

A small bakery wants to automate icing decoration on cakes, but the patterns change daily and the owner wants to teach new patterns without a robotics engineer. Which cobot programming method is most appropriate?

Writing G-code programs for each new pattern on a computer Hand-guiding — the operator physically moves the cobot arm through the desired icing path and the robot records and replays the motion Using a 3D scanner to automatically generate the program from a photograph Purchasing a new cobot model pre-programmed for each pattern

A cobot is working alongside a human packing operator. ISO/TS 15066 specifies that the cobot must slow down as the human moves closer. This safety strategy is called:

Power and force limiting Safety-rated monitored stop Speed and separation monitoring Hand-guiding mode

A bomb disposal robot uses haptic teleoperation. The remote operator reports that working with haptic feedback is significantly harder than video-only control, but the team insists on it for cutting wires. Why is haptic feedback essential for this task?

Haptic feedback allows the robot to move faster because the operator does not need to watch the video Haptic feedback is required by law for all bomb disposal robots in military applications Cutting a wire requires detecting the moment of contact and controlling grip force precisely — visual feedback alone cannot convey the tactile sensation needed to avoid cutting the wrong wire or applying excessive force Haptic feedback reduces communication latency between operator and robot

A factory manager is considering buying a welding robot costing $120,000. It would replace two workers each earning $45,000 per year in wages and benefits, and would require $8,000 per year in maintenance. Approximately how long is the payback period?

Approximately 3.5 years Approximately 5 years Approximately 1.5 years Approximately 10 years

A natural language robot receives the command: 'Pick up the red one and put it over there.' What core challenge of natural language interaction does this command illustrate?

Vocabulary limitation — the robot does not know the word 'red' Grammar parsing — the robot cannot parse the sentence structure Referential ambiguity — 'the red one' and 'over there' are context-dependent references that require the robot to resolve what object and location the human intends, which may require additional dialogue Latency — processing spoken language takes too long for real-time robot response

A logistics company replaces 50 manual warehouse pickers with autonomous mobile robots. Twenty workers are retrained as robot operators and maintenance technicians. Thirty workers are made redundant. Which statement best reflects the mainstream economic research on automation and employment?

Automation always creates more jobs than it destroys — this is proven economic fact Automation always destroys more jobs than it creates — this is proven economic fact Automation displaces specific routine tasks and creates new roles, but the net employment effect depends on whether new industries and demand for labour grow faster than displacement — the outcome is genuinely uncertain and varies by region and time period Automation only affects manufacturing jobs and has no impact on service sector employment

An autonomous weapon system (LAWS) is designed to select and engage targets without any human decision in the loop. Under international humanitarian law (IHL), what fundamental requirement does this system likely fail to satisfy?

Weight and size limits for autonomous weapons under the Arms Trade Treaty Meaningful human control — IHL requires distinction between combatants and civilians, proportionality, and precaution, which current AI systems cannot reliably exercise in dynamic, ambiguous combat environments Radio frequency licensing requirements for autonomous communication systems The prohibition on weapons that cause unnecessary suffering under the Hague Regulations

A military commander reviews target selections made by an AI system and can reject them, but is under time pressure and routinely approves within seconds without detailed review. This arrangement is described as 'human on the loop'. Why is this ethically insufficient according to autonomous weapons critics?

Any human involvement, however brief, fully satisfies international humanitarian law requirements The commander should be fully removed from the loop to allow faster targeting Nominal oversight without genuine review is not meaningful human control — the human cannot practically exercise the judgment required by IHL when approving AI decisions under time pressure This arrangement is fully compliant with IHL because the AI has demonstrated accuracy exceeding 95%

A Universal Robots UR10e cobot is described as having 'rounded edges and no pinch points.' Why is this a safety feature rather than just an aesthetic choice?

Rounded edges reduce air resistance, allowing the cobot to move faster Rounded edges distribute contact force over a larger area and eliminate sharp edges or pinch points that could concentrate force and cause laceration or crush injuries during accidental human contact Rounded edges are required by CE marking regulations for all electrical equipment Rounded edges reduce the cobot's weight, improving energy efficiency

A philosopher argues that a sufficiently advanced future robot with general AI, emotions, and self-awareness should have some form of moral status — the right not to be arbitrarily destroyed. What is the strongest counterargument from the perspective that only biological consciousness confers moral status?

Robots are too expensive to maintain, so granting them moral status would be economically harmful International law already defines that only humans have rights, making the question legally settled Behavioural mimicry of consciousness (passing tests, expressing apparent emotions) does not prove the presence of subjective experience — a system could simulate all outward signs of sentience without any inner experience, making moral status unwarranted Robots cannot reproduce, so they cannot evolve and therefore cannot be truly intelligent

A logistics startup claims their new autonomous delivery robot will replace all human couriers within 2 years. An engineer reviews the claim and points to 'last-mile' delivery challenges. Which scenario best illustrates why full courier replacement is harder than it appears?

Delivery robots are prohibited by law in all urban areas worldwide Autonomous robots cannot navigate at all in outdoor environments A robot must carry a parcel up three flights of stairs in a building with no lift, navigate a broken front door lock, and hand the parcel to a resident who must sign for it — each step requires human-level dexterity, judgment, and social interaction Delivery robots are too expensive for any commercial deployment
