Robot Safety in Industrial and Service Robotics

What is it?

Robot safety is the discipline of designing, integrating, and operating robots in a way that prevents harm to humans, equipment, and the environment. It combines engineering controls (cages, sensors), administrative controls (training, procedures), and inherent safe design.

How it works

A typical industrial robot cell includes: a perimeter fence with interlocked gates, light curtains or laser scanners that stop the robot if a human enters, hard-wired emergency stops, two-handed control switches for manual mode, and a safety PLC that handles all critical inputs and outputs.

Real-world example

In a Maruti Suzuki body shop, every welding robot is inside a cage with multiple E-stops, redundant safety PLCs, and laser scanners. Indian standards (BIS) increasingly align with ISO 10218.

Why it matters for robotics

A single robot accident can shut down a plant for weeks and end careers. Robot safety is not optional — it is the foundation of every commercial robotics deployment.
