Funded PhD Opportunity Learning by Doing – teaching a robot complex skills
This opportunity is now closed.
Subject: Computer Science and Informatics
Continuous advancements in robotics show that robots are being increasingly equipped with complex skills to solve a variety of problems. These skills are the result of research being conducted in laboratories and companies, crafted by developers and tested in sample environments. However, unlike a computer program, a robot has to operate in a world where the possibilities are potentially infinite and where it has to continuously adapt its basic programmed skills to face previously unforeseen situations. Unfortunately, there has been no successful development of robots that are autonomously capable of improving or adapting the basic skills with which they were initially equipped – something that comes natural to humans.
In this project, we propose to address these problems by developing a new skills building framework that allows a robot to successfully complete complex tasks by using previously learned primitive actions obtained from a skills library that resides in the Cloud. This library will be populated with primitive actions, such as grasping or object manipulation, from many robot sources, therefore vastly increasing the knowledge available for robots when faced with an unknown complex task utilising a combination of tactile, vision and action sensor data. To acquire these primitive actions, an approach known as Dynamic Motion Primitives (DMPs) will be used to imitate the bahaviour of a human’s action . This one-shot learning approach will enable robot skills to be derived from observations of a human's solution to a task, omitting the requirement to analytically decompose and manually program a desired behaviour. The developed framework will combine such primitive actions in a hierarchical manner to accomplish tasks that require a more complex solution. On achieving this, we will further extend the approach to enable multiple robots to co-operate on a single task, utilising cognitive approaches for task allocation based on existing robot skills or a robot’s capability to perform a new skill. We will incorporate recent advances developed in the European project RoboHow , where previously learned primitive actions are obtained from a skills library residing in the Cloud, populated with primitive actions from many robot sources.
This project will make use of mobile robots that are available in the ISRC robotics lab , in particular the state of the art PR2 mobile manipulator robot , the Schunk manipulator arm robots , the BioTAC sensors and the Vicon system. The skills library will use a cloud architecture service such as Microsoft Azure  as a platform for robot knowledge sharing.

Vice Chancellors Research Scholarships (VCRS)
The scholarships will cover tuition fees and a maintenance award of £14,777 per annum for three years (subject to satisfactory academic performance). Applications are invited from UK, European Union and overseas students.
The scholarship will cover tuition fees at the Home rate and a maintenance allowance of £ 14,777 per annum for three years. EU applicants will only be eligible for the fees component of the studentship (no maintenance award is provided). For Non EU nationals the candidate must be "settled" in the UK.
