Problem statement

The railways in the Netherlands are very vulnerable for all kinds of things. Think for example of fallen leaves, snow, weeds, dead animals, etc. These factors lead to unwanted delays. This autonomous robot is designed to tackle this problem and prevent delays from happening.

Subject

Autonomous railway cleaning robot

Objectives

• The system must be able to navigate through the Dutch railway system autonomously
• The system must be able to recognize the different obstacles on the railway
• The system must be able to clean the railway from obstacles autonomously.
  • For special occasions the system must alert the involved companies
• The system must provide a short-term solution for certain problems
• The system must avoid colliding with obstacles
• The system must be deployable at any time
• The system must not hinder the human operated train traffic

Users

The NS and ProRail. Indirect users are the train-users.

State of the Art

The past project of PRE2016 3 Group 3 was conducted in a similar design case. Hence, the wiki of this project was analysed along with the 63 references of their wiki page (numbered 1 - 63). However, some of these references could not be found anymore, as this project was conducted in 2016. Under each analyzed reference a short sentence describes a summary and relevance to our project.

    The Netherlands has the busiest railways in all of Europe, in 2015 3.3 million train journeys have been made, which results in a total covered distance of 152 million kilometers (this is approximately the distance between earth and the sun). ProRail owns 7021 kilometers of tracks and there are 404 train stations, of which some are only used in special occasions.

    The usage of a CPU results in wear, the lifespan of silicon transistors in the CPU are around 20-30 years. Most CPU can last longer than a decade. It really is hard to specify the lifespan, since every unit is used differently and the chips are just different on microscopic level.
