Postgraduate Course: Robot Learning and Sensorimotor Control (INFR11142)
|School||School of Informatics
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 11 (Postgraduate)
||Availability||Available to all students
|Summary||This course is designed as a follow up to the introductory course on Robotics: Science and Systems and will gear students towards advanced topics in applying Machine Learning towards Adaptive Control and Planning in Robots and in using these insights to understand human sensorimotor control. Control of complex, compliant, multi degree of freedom (DOF) sensorimotor systems like humanoid robots or autonomous vehicles have been pushing the limits of traditional planning and control methods.
This course aims at introducing a machine learning approach to the challenges and will take the students through various aspects involved in motor planning, estimation, prediction, optimal control and learning for adaptation with an emphasis on the computational perspective. We will learn about statistical machine learning tools and methodologies particularly geared towards problems of real-time, online learning for robot control.
Specific methods for implementing optimal control in real world systems with contacts and learning methods geared towards making them adaptive will be explored. Issues and possible approaches for learning in high dimensions, planning under uncertainty and redundancy, sensorimotor transformations and stochastic optimal control will be discussed. This will be put in context through exposure to topics in human motor control, experimental paradigms and the use of computational methods in understanding biological sensorimotor mechanisms.
