Distance-Aware Dynamically Weighted Roadmaps for Motion Planning in Unknown Environments

RA-L 2018

The paper presents and evaluates a distance-aware dynamic roadmap (DA-DRM) algorithm as an extension of the dynamic roadmap (DRM) approach. In contrast to previous work, the algorithm is capable of planning collision-free trajectories while considering the distance to obstacles, even in unknown envi

Grasping of Unknown Objects Using Deep Convolutional Neural Networks Based on Depth Images

ICRA 2018poster

We present a data-driven, bottom-up, deep learning approach to robotic grasping of unknown objects using Deep Convolutional Neural Networks (DCNNs). The approach uses depth images of the scene as its sole input for synthesis of a single-grasp solution during execution, adequately portraying the robo…

Planning High-Quality Grasps Using Mean Curvature Object Skeletons

RA-L 2018

In this letter, we present a grasp planner that integrates two sources of information to generate robust grasps for a robotic hand. First, the topological information of the object model is incorporated by building the mean curvature skeleton and segmenting the object accordingly in order to identif

A combined approach for robot placement and coverage path planning for mobile manipulation

IROS 2017poster

Robotic coverage path planning describes the problem of determining a configuration space trajectory for successively covering a specified workspace target area with the robot's end-effector. Performing coverage path planning for mobile robots further requires solving the problem of robot placement,…

Heuristic 3D object shape completion based on symmetry and scene context

IROS 2016poster

Object shape information is essential for robot manipulation tasks, in particular for grasp planning and collision-free motion planning. But in general a complete object model is not available, in particular when dealing with unknown objects. We propose a method for completing shapes that are only p…
