Position-based monocular visual servoing of an unknown target using online self-supervised learning

IROS 2019poster

Visual servoing, i.e. control with visual information, is a valuable capability in many robotic applications. In particular, position based visual servoing (PBVS) estimates position information from the observed image to generate visual servo control. However, the estimation of the position of an un…

Learning and Generalization of Dynamic Movement Primitives by Hierarchical Deep Reinforcement Learning from Demonstration

IROS 2018poster

This paper presents an approach to learn and generalize robotic skills from a demonstration using deep reinforcement learning (deep RL). Dynamic Movement Primitives (DMPs) formulate a nonlinear differential equation and produce the observed movement from a demonstration. However, it is hard to gener…

Vision-based Target Tracking for a Skid-steer Vehicle using Guided Policy Search with Field-of-view Constraint

IROS 2018poster

This paper describes a vision-based target tracking method for a skid-steer vehicle. With the development of deep reinforcement learning, many researchers have tried to generate an end-to-end policy to control the mobile robot from a raw pixel image data. However, the action in most research only co…
