Three Laws of Robotics

1. A robot must not harm a human being,
nor through inaction allow one to come to
harm.

2. A robot must always obey human beings,
unless that is in conflict with the first law.

3. A robot must protect itself from harm,
unless that is in conflict with the first or
second laws.

Major Emphasis

To carry out hazard identification, risk assessment
and apply appropriate risk controls;

Specific obligations on Designers, Manufacturers,
Erectors, Installers, Employers; and

Considers various stages in life of plant: design,
construction, installation, commissioning, detection,
maintenance, use, set-up, cleaning, repair,
dismantling, storage, disposal.

Summary of Robot Safety

DESIGN guards that are “practicable”
and operable, considering types and
frequency of access

Meet relevant Standards

Must not be easily defeated

Must not create additional risk
