Robotics and Autonomous Systems (S199) Page 2 Executive Summary TRL and RSSB launched a community of interest for conducting a technology watch on robotics and autonomous systems. After having reviewed the possible themes which could be covered, and considering our respective fields of expertise, it was decided that the technology watch would focus on robotics and autonomous systems for rail asset management and maintenance, and automation in vehicles and transport systems. The resulting report looks at the fields of robotics and autonomous vehicles to identify some of the latest technological advances and innovations, highlight their possible applications and benefits for the transport industry, and discuss their future trends, challenges and opportunities. The term “Robotics” is used to define a branch of engineering that focuses on the design, construction and operation of machines specifically designed to perform a particular task (or a range of tasks). They are usually classified according to their application (e.g. military, healthcare, industrial robots, etc.) or their appearance (e.g. drones, humanoid robots, hexapods, etc.). While robots are usually viewed as physical machines performing some form of physical action, autonomous systems cover a much wider spectrum, which is not defined by physical structures. Autonomous systems are defined as self-monitoring adaptive intelligent systems that have control over their own actions and internal state, and that can operate independently from direct human intervention. This may include robotics or autonomous vehicles, where data acquired by a sensing or monitoring capability are utilised as part of the overall autonomous decision-making process. Robots can be used to replace or assist humans in any activity that falls under what certain technology analysts have called the “4Ds” type: dangerous, difficult, dirty or dull. Some of the possible application areas include inspection and maintenance, monitoring and surveillance, disaster recovery, customer services and network optimisation. Some of the technologies identified in the technology watch include drones for maintenance, inspection and surveillance (graffiti deterrence, trespassing monitoring, etc.), rail robots for automatic switch inspection and welding work, laser coating renewal systems, 3D printing robots for structural work, mobile robots for disaster recovery and exoskeletons for personal assistance. Autonomous systems show great potential for the transport sector with a number of applications already developed, which enable better vehicle performance (tilting trains, automatic suspension, etc.), higher fuel efficiencies (automatic engine optimisation software, hybrid drives, etc.) and better optimised transport networks (semi-autonomous signalling systems, driverless pods and light rail vehicles, etc.). They are especially good in situations where human involvement is expensive, dangerous, difficult or superfluous. Autonomous system applications can be beneficial in manufacturing, maintenance, network optimisation, safety and security, disaster recovery, passenger experience and staff training areas. Some of the autonomous systems identified in the technology watch include driverless cars, autonomous rail vehicles, driver assistance and cooperative systems and artificial intelligence. The prospects for more widely adopting robotics and autonomous systems in the transport sector will dependent on a number of factors, such as Technology Readiness Levels (TRL), associated costs, regulations and policies, time scales, performance, reliability, etc. Societal developments will also play a fundamental role, as drivers or barriers.

HSR is a capital-intensive infrastructure, in which multiple subsystems are closely integrated. Also, HSR operation lasts for a long period, and its performance indicators are continuously altered by incremental updates.

The autonomous vehicle is a game changer, not least because the traditional differences between the various modes of transport become indistinct as an autonomous vehicle can be everything, in principle: a private car, a taxi, a bus, a car-sharing vehicle or a shared taxi. To express it dramatically: the autonomous vehicle could be part of the public transport system – but it could also seriously threaten the existence of today’s public and long-distance transport: The autonomous vehicle can threaten the existence of public transport because it makes driving much more attractive.
