Data-efficient Co-Adaptation of Morphology and Behaviour with Deep Reinforcement Learning
Data-efficient Co-Adaptation of Morphology and Behaviour with Deep Reinforcement Learning

A novel approach combining deep reinforcement learning and design optimization in such a way that it is directly applicable to robots in the real world. This approach caters especially to roboticist who have access to only a single design/robotic prototype at a time. This paper is currently under review for the Conference of Robot Learning 2019.

Improved Exploration through Latent Trajectory Optimization in Deep Deterministic Policy Gradient
Improved Exploration through Latent Trajectory Optimization in Deep Deterministic Policy Gradient

A Baxter robot learned to insert a cylinder, dangling from a string, into a tube using only camera images. I investigated here if we can learn a policy faster when using explorative actions generated from a trajectory optimizer. The optimization algorithm used a deep Q-network as objective function.

From the Lab to the Desert
From the Lab to the Desert

A sea turtle inspired robot manufactured from a paper laminate was trained to find the optimal locomotion strategy on different types of granular media, for example poppy seeds and real desert sand.

Extracting Bimanual Synergies with Reinforcement Learning
Extracting Bimanual Synergies with Reinforcement Learning

This project investigated the latent spaces discovered throughout the training process of Sparse Latent Space Policy Search. We were especially interested in bi-manual synergies for lifting tasks. The Baxter robot received here only a reward and no sensory information about the environment.

Sparse Latent Space Policy Search

A novel reinforcement learning algorithm based on Latent Space Policy Search. We integrate Group Factor Analysis and reinforcement learning into one probabilistic learning framework. By creating several groups of actions we are able to learn specific latent spaces which either capture intra-group or inter-group relations.

Latent Space Policy Search
Latent Space Policy Search

A novel reinoforcement learning algorithm which extracts automatically a low dimensional action space for better and faster exploration. The main idea is to learn the (probabilistic) principal components of actions which achieve high reward and explore this latent space during training.
