Train cleaning robots are being developed in Scotland, UK, to protect the health and safety of employees. At the same time, this will also avoid train delays.
During the Covid-19 pandemic, the cleanliness of train carriages has become increasingly important. A 2020 survey of more than 50,000 UK rail passengers found that one in four were dissatisfied with the cleanliness of trains.
Scientists at Heriot-Watt University's National Robot Museum have built a model of a cleaning robot with a 180-degree field of view, which has both a static camera and a stereo vision camera. The robot also has four wheels and a reversible brush for cleaning hard-to-reach areas between the cabin seats and below. Scientists plan to build and market the train-cleaning robot based on the model in the first half of 2022.
The researchers spent two years collating 58,300 images of railroad and carriage litter to help robots identify objects more accurately. Now, the team is designing and developing an easy-to-use, accurate navigation system that can be used to guide the robot. It is also working on a waste detection algorithm.
Project leader Dr Mustafa Suphi Erden said: "The area under the seats of older trains is a challenge for the cleaners - they spend a lot of time collecting every piece of rubbish from under and between the seats and it is currently Manual work, long hours of work, can lead to health problems for cleaners. In addition, the operation of cleaning robots can help avoid train delays. With the increasing pressure on railway services, efficient cleaning of trains has become critical. "
