Universal Manipulation Policy Network for Articulated Objects

چکیده

We introduce the Universal Manipulation Policy Network (UMPNet) – a single image-based policy network that infers closed-loop action sequences for manipulating articulated objects. To infer wide range of trajectories, supports 6DoF representation and varying trajectory length. handle diverse set objects, learns from objects with different articulation structures generalizes to unseen or categories. The is trained self-guided exploration without any human demonstrations, scripted policy, pre-defined goal conditions. support effective multi-step interaction, we novel Arrow-of-Time attribute indicates whether an will change object state back past forward into future. With inference at each interaction step, learned able select actions consistently lead towards away given state, thereby, enabling both goal-conditioned manipulation.

Multi-Step Planning for Robotic Manipulation of Articulated Objects

Multi-step planning is a process that allows us to solve complex problems by using a hybrid of a continuous kinematic planner and discrete search algorithm. In this paper we demonstrate how to formulate practical robotic manipulation tasks into this planning framework by applying the approach to that of a robot planning to fold a typical folding chair. We believe that this planning approach cou...

Whole-Body Motion Planning for Robotic Manipulation of Articulated Objects

In this thesis, we present a sampling-based approach to generate whole-body motions for a humanoid robot. In particular, the planner developed is capable to generate valid whole-body motions for body repositioning as well as for grasping and manipulation of articulated objects, such as doors or drawers. Besides the generic constraints involved in motion planning, such as joint limits and collis...

Occlusion-aware multi-view reconstruction of articulated objects for manipulation

The goal of this research is to develop algorithms using multiple views to automatically recover complete 3D models of articulated objects in unstructured environments and thereby enable a robotic system to facilitate further manipulation of those objects. First, an algorithm called Procrustes-Lo-RANSAC (PLR) is presented. Structure-from-motion techniques are used to capture 3D point cloud mode...

Interactive Manipulation of Articulated Objects with Geometry Awareness

Techniques for interactive 3D manipulation of articulated objects in cluttered environments should be geometrically aware, going beyond basic inverse or forward kinematics to allow contact while preventing interpenetration. This paper describes a general purpose interactive object manipulation technique using nonlinear optimization. The method converts geometry awareness into sets of inequality...

Towards Understanding Articulated Objects

Robots operating in home environments must be able to interact with articulated objects such as doors or drawers. Ideally, robots are able to autonomously infer articulation models by observation. In this paper, we present an approach to learn kinematic models by inferring the connectivity of rigid parts and the articulation models for the corresponding links. Our method uses a mixture of param...
