Real Hardware Testing of Autonomous Vehicle Platooning- Demo

 

We have tested our Agent-based development of Autonomous Vehicle Platooning on Jaguar Rovers. We have tested the joining scenario for a platoon of size 3. Initially, the platoon consists of two vehicles, the leader (front rover in the video) and only one follower (middle rover in the video). We have shown that the last rover in the video, controlled by an agent, successfully joins the platoon.

 

 

This work is a joint work between the Universities of Liverpool and Sheffield and the Virtual Engineering Centre, University of Liverpool (David Bowman, Ken Lai and Konstantin Vikhorev).

 

Autonomous Vehicle Platooning — Demo

An automotive platoon, enabling road vehicles to travel as a group, is led by a vehicle which is driven by a professional driver. We employ a hybrid agent architecture for development of automotive platoon.  Our agent-based development of automotive platoon where the discrete decision-making component of the system is separated from the continuous control system as sketched below:

HybridArchPlatooning

Real-time continuous control of the vehicle is managed by feedback controllers, implemented in MATLAB, and observing the environment through its sensory input. This is called the Physical Engine. The Physical Engine, in turn, communicates with an Abstraction Agent that extracts discrete information from streams of continuous data and passes this on a Decision-Making Agent. The Decision-Making Agent is a rational agent which directs the Physical Engine by passing it instructions through the Abstraction Agent. Instructions from the Decision-Making Agent to the Abstraction Agent are interpreted into meaningful instructions for Physical Engine.

To provide the complex environment necessary for effective simulation and testing, we use an automotive simulator, TORCS, to implement the environment component of the architecture. The Physical Engine is implemented in MATLAB, while both Abstraction and Decision-Making Agents are programmed in an agent-based programming language called GWENDOLEN. . An interface between TORCS and MATLAB/Simulink has been developed that provides a means to control vehicles from MATLAB and Simulink, which can be found here.

Robot ethics as an emerging field: some data

Recently, I analyzed some bibliometric data to demonstrate the emergence of robot ethics as a field. The data and the full blog post can be found at:

The data presented in the blog post, provide some evidence that the field of robot ethics is on the rise, both in academia and beyond. In all, the data add to the intuition that the ethical aspects of robotics is becoming more of an issue. For example, the 1st International Workshop on AI and Ethics was held in 2015. Also, influential news sites around the net (including Nature News: here and here) are picking up on stories related to robot ethics. Finally, various initiatives to regulate the ethics of robotics have emerged. This increased attention for ethical issues seems to be reflected in the publication record. With robots able to fire without human intervention becoming a (scary) reality (see video in the original post), the interest in robot ethics might not have come too soon.
