This course aims to introduce the advanced state-of-the-art deep learning methods used in robotics. The methods are studied in robotic reinforcement learning, behavior cloning, learning from demonstration, imitation learning, predictive world modeling, and hybrid reasoning tasks. The students are expected to learn the details of these methods, their motivations and limitations in different robotic problems. The students are also expected to acquire hands-on experience on these methods. A simulated robotic environment in PyBullet with an arm-hand robot and relevant sensors is provided to the students. Using the relevant deep learning libraries, the students are expected to implement robot learning frameworks where the robots learn to acquire desired skill sets.
The homeworks can be implemented in pairs, however the partner should change in each homework. The robot simulation environment or the robot interaction dataset is provided to the students in homeworks.
A group of (up to 3) students extend one of the methods they implement and submit this extension to a local journal. Submission to the journal is a must for the project to be eligible for evaluation.
