Unit 2: Safety for Robot Work Cell

What are the Three Laws of Robotics developed by Isaac Asimov?

• A robot must not harm a human being, a robot must always obey human beings, a robot must destroy itself if it causes harm

• A robot must not harm a human being, a robot must always obey human beings, a robot must protect itself from harm

• A robot must not harm a human being, a robot must always obey human beings, a robot must protect itself from harm unless it conflicts with the first law

• A robot must not harm a human being, a robot must always obey human beings, a robot must protect itself from harm unless it conflicts with the first and second law

What are the causes of employee injury in a robotic environment?

• Being struck by a part or by robot gripper, exposure to dangerous levels of heat or electricity, excessive physical strain

• Parts of the body being caught in the automation system, falling from equipment or structure, slipping or tripping on walking or working robot

• Being struck by a part or by robot gripper, falling from equipment or structure, exposure to dangerous levels of heat or electricity

• Parts of the body being caught in the automation system, slipping or tripping on walking or working robot, excessive physical strain

What is the primary function of safeguarding devices in a robot work cell?

• To provide a warning, to restrict traffic flow in the area

• To restrict human traffic in Zone 1, to allow only programmers in Zone 2

• To eliminate hazards in the workplace, to apply safeguarding technology

• To ensure robots operate without causing harm, to protect the environment

What is the purpose of laser sensors in a work cell?

• To project a laser beam into the working area, to define the safety zone

• To detect the presence of an intruder in the work cell, to provide a warning signal

• To provide a physical barrier around the robot's work envelope, to shut down the robot if any person enters the work envelope

• To sense the presence of a person and cause appropriate action, to safeguard the person from hazardous conditions

What is the process of evaluating the risks to safety and health arising from hazards at work?

• Risk reduction, hazard identification, risk assessment

• Risk assessment, risk estimation, hazard reduction

• Risk estimation, risk reduction, hazard identification

• Hazard reduction, risk assessment, risk estimation

What are the guidelines fundamental to the practice of planning, management, and operation?

• Hazard identification, risk assessment, risk control

• Risk reduction, risk assessment, risk estimation

• HIRARC, HIRARC, HIRARC

• Risk assessment, risk estimation, hazard reduction

What is the main purpose of interlock devices in a work environment?

• To ensure reliable operation under extreme conditions and rough treatment

• To provide a warning signal in case of danger

• To prevent any operation until certain conditions exist

• To allow an operation to be performed under any conditions

What is the function of presence sensing devices in a robot work cell?

• To restrict traffic flow in the area

• To shut down the robot if any person enters the work envelope

• To sense the presence of a person and cause appropriate action

• To provide a physical barrier around the robot's work envelope

What is the purpose of light curtains in a work cell?

• To sense the presence of a person and cause appropriate action

• To provide better guarding compared to traditional guarding

• To provide a physical barrier around the robot's work envelope

• To shut down the robot if any person enters the work envelope

What is the primary function of safeguarding devices in a robot work cell?

• To provide a warning, to restrict traffic flow in the area

• To ensure robots operate without causing harm, to protect the environment
