Cleaning robots and security: what happens if someone steps in front of it?

A modern cleaning robots one of the basic principles of safe operation is that recognise obstacles, and avoid a collision. Manufacturers are equipping robots with sensors that allow them to move safely between people in busy places - such as offices, restaurants, hotels or shopping malls.

1. The robot detects the obstacle

A most cleaning robots uses multiple sensors to detect the environment, for example:

  • collision sensors
  • distance sensors
  • infrared or ultrasonic sensors
  • sensors on the front and side of the robot

These monitor what is in front of the robot in real time and react immediately if a person, animal or object gets in its way.

2. The robot slows down or stops

If someone suddenly steps in front of the robot:

  • slow down,
  • stop by,
  • or deviates from its previous route, to get around the obstacle.

This functionality is an essential safety feature for all modern cleaning robots.

3. The robot does not exert dangerous forces

A cleaning robots are travelling at low speeds and do not exert a force that could cause injury. The weight/power of the obstacle sensors and the robot are designed to ensure that the robot cannot cause a dangerous collision.

4. The device navigates in a way that minimises contact

The developers' priority is to make the robot avoid physical contact.
Most cleaning robots:

  • stops safely in front of an obstacle,
  • is placed laterally,
  • or choose a new route.

This also works when there are more people moving around in the space.

5. Robots are designed to work with humans

A professional cleaning robots can be used in everyday, busy environments.
They are therefore designed to:

  • react to unexpected movements,
  • slow down near groups or children,
  • move in a stable and predictable way.

Summary

If someone suddenly steps in front of the cleaning robot, the robot detects an obstacle immediately, then stop or avoid it.
Modern cleaning robots operate at relatively low speeds, with safe force limits and are specifically designed to operate reliably and safely in human environments.
