We are currently working with four different platforms, namely the trucks, the quadrocopters, the Nexus mobile robots, and the research concept vehicle. You can know more about each of these agents by reading the text below.
The Smart Mobility Lab allows researchers to experiment new ideas about trucks traffic without jeopardizing the hazards that come with real testing. But why are we doing research about trucks?
The trafﬁc intensity will continue increasing making trafﬁc congestions a major concern for decision makers. Naturally allying to traffic come the gas emissions and companies interests in saving time and money while delivering the goods. To work around these problems, ways to increase efficiency are being studied.
One of the ways to decrease fuel comsuption is by driving in formations, as platoons. This allows Heavy Duty Vehicles to take advantage of the air drag reduction that is a consequence of trucks driving close to each other. This would only be possible with automatic control since drivers would not feel comfortable maintaining a small distance to the truck ahead. Further, due to this small distance, traffic congestions are reduced since the driving area of the road increases.
Another way is to anti-platoon. Although it seems contradictory with the previous idea, the purpose is to avoid these Heavy Duty Vehicles to stop when there is a road where trucks are only allowed to pass by from time to time (some minutes) because of road recovering properties. This allows fuel saving on the trucks startup that are allied with great ammounts of fuel comsuption.
A further way of efficiency improvement involves knowing real traffic data to avoid congestions and thereby taking less time to deliver the goods. Also it can avoid these Heavy Duty Vehicles to stop for instance in a one-way section of the road or in traffic lights.
Regarding air vehicles, automatic control was always a major concern on their development. The Smart Mobility Lab ensures safe experimenting and testing of these air vehicles, namely the quadrocopters.
The interest of mankind for aerial vehicles in general has always been ﬂourishing. The concept of Unmanned Air Vehicles (UAVs) results in several main applications: intelligence gathering, surveillance, platooning, as well as climate and pollution monitoring, rescuing operations, pipeline inspection. The success of this technology relies in replacing the human presence when navigation and maneuver in adverse or uneasily reachable environments is needed.
The use of quadrocopters in the Lab also allows to test scenarios of following trucks and obstacle avoidance.
The Nexus mobile robots are tested in the Smart Mobility Lab to explore several types of applications.
As it is known today Robotics has major interests when it comes to dull or dangerous jobs humans rather prefer not to do. The Nexus is able to explore the environment with a robust technique of moving around the floor. Automatic Control applied to the Nexus robots allows exploring an environment where humans are not able to go for instance due to healthy reasons. As a result, Nexus is an interesting robot to study due to its unique characteristics of locomotion.
Furthermore, exploring this type of robots allows developing multi-agent systems simulation and communication. In partially-known environments, Nexus can change its controllers and plans accordingly. In the Lab one can also simulate environments with several obstacles which the robot avoids.
Research Concept Vehicle
The KTH Research Concept Vehicle is a rolling research and demonstration laboratory for vehicle research concerning sustainable transport systems. The purpose of the vehicle is to have a platform where research results can be implemented and evaluated in real-life.
The project ”Research Concept Vehicle” (RCV) aims at realizing a research-based concept vehicle that will be used to validate and demonstrate current and future research results. The design is modular to include research from several disciplines and the design is highly versatile enabling a wide array of different functions to be tested, e.g 2WD, 4WD, 2WS, 4WS, torque vectoring, SBW, etc.
The RCV have been developed at KTH Transport Labs through an collaborative effort between both researchers and students from multiple Schools and Departments at KTH.
