Robotics in the Workplace: An Overview

Key points

  • U.S. companies are using robots more often to perform dangerous or repetitive tasks.
  • Increasing numbers and new types of robots in the workplace have created a knowledge gap related to worker safety and health.
  • NIOSH is providing scientific leadership to address the safety and health of workers who use, wear, or work near robots.

Why it's important

Robots have existed in the workplace for many years, but their numbers and capabilities are quickly growing. Robots can enhance worker safety, health, and well-being. However, there are also safety concerns.

Facts

  • A NIOSH analysis identified 41 robot-related fatalities in the U.S. between 1992-2017.1
  • The number of industrial robots in U.S. factories grew by 10% in 2022.2
  • The number of service robots sold for professional use in the U.S. rose to 158,000 units in 2022—a 48% increase.2

Types of robots

Robots are machines or automated technologies that can perform a series of actions. They can do everything from drive cars to perform surgery. You can find various types of robots in today's workplaces:

Traditional industrial robots work in robotic cells and cages away from human workers.

Professional service robots assist workers in completing tasks. These include:

  • Remotely controlled or autonomous vehicles
  • Unmanned aerial vehicles (UAVs) or drones

Collaborative robots directly interact with people. These include:

  • Wearable robotics or powered exoskeletons
  • Co-existing or mobile robots that can navigate through the workplace

Impacts

Robots can improve worker safety, health, and well-being by doing work in high-risk environments. For example:

  • Robots could inspect offshore oil rigs while people remain safely on shore.
  • Drones might allow farmers to apply pesticide without exposure to chemicals.
  • Service robots may help healthcare workers safely lift patients without the risk of musculoskeletal injuries.
  • A fleet of self-driving vehicles could reduce motor vehicle crashes among delivery workers.

Risks

Robots can improve safety and productivity in the workplace. However, there are also potential hazards associated with using robot systems. Hazards to workers might include:

  • Struck-by or caught-between hazards
  • Crushing and trapping
  • Slipping, tripping, and falling hazards
  • Electrical hazards3

Emerging risks

The increasing use of robots that work in close proximity to people brings new risks to the workplace. These emerging risks may not yet be fully understood. Robots working near people could:

  • Injure workers through unexpected contact
  • Distract workers from hazards
  • Cause workers mental stress
    • Distrust of the robot's capabilities
    • Concern about job loss

Safety and health professionals must continually ensure that the use of robots does not create additional hazards or risks to workers. This is important as technology advances and workplace applications change.

What's being done

NIOSH's Center for Occupational Robotics Research addresses the safety, health, and well-being of workers who use, wear, or work near robots.
