Abstract [en]

Recent advances in machine learning have triggered an enormous interest in using learning-based approaches for robot control and object manipulation. While the majority of existing algorithms are evaluated under the assumption that the involved bodies are rigid, a large number of practical applications contain deformable objects. In this work we focus on Deformable Linear Objects (DLOs) which can be used to model cables, tubes or wires. They are present in many applications such as manufacturing, agriculture and medicine. New methods in robotic manipulation research are often demonstrated in custom environments impeding reproducibility and comparisons of algorithms. We introduce ReForm, a simulation sandbox and a tool for benchmarking manipulation of DLOs. We offer six distinct environments representing important characteristics of deformable objects such as elasticity, plasticity or self-collisions and occlusions. A modular framework is used, enabling design parameters such as the end-effector degrees of freedom, reward function and type of observation. ReForm is a novel robot learning sandbox with which we intend to facilitate testing and reproducibility in manipulation research for DLOs.

Abstract [en]

Recent advances in artificial intelligence and machine learning have significantly impacted the field of robotics and led to the interdisciplinary study of robot learning. These developments have the potential to revolutionize the automation of tasks in various industries by reducing the reliance on human workers. However, fully autonomous, learning-based robotic systems are still mainly limited to controlled environments. Ideally, we are looking for methods that enable autonomous acquisition of robotic skills for any temporally extended setting with potentially complex sensor observations. Classical sampling-based planning algorithms used in robot motion planning compute feasible paths between robot states over long time horizons and even in geometrically complex environments. This thesis investigates the possibility of combining learning-based methods with these classical approaches to solve challenging problems in robot manipulation, e.g. the manipulation of deformable objects. The core idea is to leverage the best of both worlds and achieve long-horizon control through planning, while using learning to obtain useful environment models from potentially high-dimensional and complex observation data. The presented frameworks rely on recent machine learning techniques such as contrastive representation learning, generative modeling and reinforcement learning. Finally, we outline the potentials, challenges and limitations of this type of approaches and highlight future directions.

Abstract [sv]

De senaste framstegen inom artificiell intelligens och maskininlärning har haft en betydande inverkan på robotikområdet och lett till det tvärvetenskapliga studerandet av robotinlärning. Dessa utvecklingar har potentialen att revolutionera automatiseringen inom olika industrier genom att minska beroendet av mänskliga arbetare. Dock är helt autonoma, inlärningsbaserade robotsystem fortfarande huvudsakligen begränsade till kontrollerade miljöer. Idealt sett letar vi efter metoder som möjliggör autonom förvärvning av robotfärdigheter för situationer med långa tidshorisonter och potentiellt komplexa sensorobservationer. Klassiska sampling-baserade planeringsalgoritmer som används i robotrörelseplanering beräknar genomförbara vägar mellan robottillstånd över långa tidshorisonter och även i geometriskt komplexa miljöer. I detta arbete undersöker vi möjligheten att kombinera inlärningsbaserade tillvägagångssätt med dessa klassiska tillvägagångssätt för att lösa utmanande problem inom robotmanipulation, t.ex. hantering av formbara objekt. Kärnidén är att utnyttja det bästa av båda världarna och uppnå långsiktig kontroll genom planering, samtidigt som man använder inlärning för att erhålla användbara miljömodeller från potentiellt högdimensionella och komplexa observationsdata. De presenterade ramverken förlitar sig på senaste maskininlärningstekniker såsom kontrastiv representationsinlärning, generativ modellering och förstärkningsinlärning. Slutligen skisserar vi potentialerna, utmaningarna och begränsningarna med denna typ av tillvägagångssätt och belyser framtida riktningar.
