چکیده

This paper propose a novel framework for a data driven grasp planner that indexes partial sensor data into a database of 3D models with known grasps and transfers grasps from those models to novel objects. We show how to construct such a database and also demonstrate multiple methods for matching into it, aligning the matched models with the known sensor data of the object to be grasped, and selecting an appropriate grasp to use. Our approach is experimentally validated in both simulated trials and trials with robots.

Grasping of Unknown Objects using Deep Convolutional Neural Networks based on Depth Images

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 robot’s visual perception during exploration of a scene. The training input consists of precomputed h...

Active Learning for Robot Manipulation

Learning techniques in robotic grasping applications have usually been concerned with the way a hand approaches to an object, or with improving the motor control of manipulation actions. We present an active learning approach devised to face the problem of visually-guided grasp selection. We want to choose the best hand configuration for grasping a particular object using only visual informatio...

A Data-driven Approach to Predict Hand Positions for Two-hand Grasps of Industrial Objects

The wide spread use of 3D acquisition devices with highperformance processing tools has facilitated rapid generation of digital twin models for large production plants and factories for optimizing work cell layouts and improving human operator effectiveness, safety and ergonomics. Although recent advances in digital simulation tools have enabled users to analyze the workspace using virtual huma...

2D Subspaces for User-Driven Robot Grasping

Human control of high degree-of-freedom robotic systems is often difficult due to the overwhelming number of variables that need to be specified. Instead, we propose the use of sparse control subspaces embedded within the pose space of a robotic system. Using captured human motion for training, we address this sparse control problem by uncovering 2D subspaces that allow cursor control, or event...

Grasping force control of a tendon-driven prosthetic finger based on force estimation using motor current signals

A force estimation model using motor current signals was deduced in this paper for a tendon-driven prosthetic finger grasping objects with its distal phalanx. Models of the prosthetic finger were first established. As driving moment of each joint could be calculated form motor current, stable grasping force of the finger could be calculated by its statics mechanic model, that is, the grasping f...

3D Visual Data-Driven Spatiotemporal Deformations for Non-Rigid Object Grasping Using Robot Hands

Sensing techniques are important for solving problems of uncertainty inherent to intelligent grasping tasks. The main goal here is to present a visual sensing system based on range imaging technology for robot manipulation of non-rigid objects. Our proposal provides a suitable visual perception system of complex grasping tasks to support a robot controller when other sensor systems, such as tac...
