The inspection of rail vehicles, also known as rolling stock, is conventionally done by sight. Visual inspection is carried out on different components of a rolling stock for the following purposes:
For the car body (external) and saloon (interior), to check for graffiti, defects, and stains.
For the underframe and bogie, to perform sanity checks to detect potential risks, such as loose cabling, missing components, or misplaced tools.
The inspections need to be completed rapidly prior to revenue service. For the underframe and bogie, 2 inspection experts are deployed to inspect multiple vehicles at over 100 locations per car within 1 - 2 hours. A broad range of knowledge and experiences is also demanded of these inspectors to effectively spot the risks and issues. Depending on the severity of the detected abnormalities or defects, a rapid response may be required to resolve them.
We are interested in robotic solutions that can automatically conduct the inspection for one or more components of the rolling stock. The solution should meet the following requirements:
The solution should operate with minimal human intervention, and must be able to automatically detect abnormalities or defects and trigger an alert.
The solution must be small in size, within the dimensions of 1m (L) by 0.8m (H) by 0.8m (W).
The solution must be able to travel on various terrains in the depot, including rails, slopes, and stairs, and automatically avoid obstacles.
The solution should generate inspection reports with defect classifications and location pinpoints.
How might we automate the inspection of rail vehicles, in order to detect abnormalities or defects that could result in operational disruptions?
