Towards robot systems for small batch manufacturing

Abstract

In this paper, we present a prototypical system as platform for a new generation of robotic workers. Dealing with customization, individualization and finally customer driven batch sizes of products of highest quality requires robot technologies that are able to compensate uncertainties inherent in processes and environment. Existing production plants are planned for the majority of variants, but for a significant portion of all products the flexibility of human workers is still required for production. Therefore technologies are required allowing intuitive access to robotic system components without being a robot expert. The main contribution of the paper is a novel framework for robotic workers combining perception, autonomous planning and a user-centered design of human-robot interaction. We also present an industrial interface that allows the operator to immerse into complex industrial robot processes and to transfer task knowledge and strategies for commanding robots on a high-level. The framework and its embedded methods have been implemented and evaluated in a bin picking scenario for small batch sizes.

An adaptive system-of-systems approach for resilient manufacturing

“…The software consists of a visual sub-system and is fully in- tegrated with the workflow engine centurio.work. The visual subsystem, based on the XRob software framework [28], detects parts of different shapes in the preparation area and is able to generate collision free paths to a target destination. It is also capable of determining the exact positioning of the pallet on the AGV, thereby correcting positioning errors that originate from the inexact position of the AGV.…”

Towards a Digital Repertoire: Design and Fabrication of a Robotically-Milled Brass Chandelier

“…The research project explores a novel setup using a robotic arm with a milling router and a vertical axial revolving holder to fabricate a brass chandelier. The advantage of the setup using a robotic arm with a more common end-effector, such as a milling spindle, allows designers and architects to better access the technique for flexible and small-batch manufacturing [3] without compromising the fabrication quality.…”

Resolving automated perception system failures in bin-picking tasks using assistance from remote human operators

“…Examples of augmented reality systems include a tracked head worn display that augments a human operator's view with text, labels, arrows, and animations [19] and laser pointer mounted on a robot highlighting where a cable must be inserted [18]. Humans usually deliver task specific information to the robot either by teleoperation or a graphical user interface [21].…”
