The paper aims to develop a robotic deburring method based on a new active pneumatic tool.
Abstract
Purpose
The paper aims to develop a robotic deburring method based on a new active pneumatic tool.
Design/methodology/approach
The paper presents a new active pneumatic tool, which is developed by integrating two industrial pneumatic deburring tools based on a double cutting action – initial cut followed by fine cut. A simple control method is developed, which coordinates the motion of the tools and the arm.
Findings
The study finds that the developed method can improve robotic deburring in terms of speed and accuracy.
Research limitations/implications
The paper provides guidance for the design of a pneumatic deburring tool, its integration with an industrial robot, and robotic deburring control.
Practical implications
The new deburring tool prevents large contact force and bouncing from occurring during the contact transition. In addition, the developed deburring method demonstrates significant improvement in deburring speed and accuracy in comparison with other methods, which is translated into cost‐effective deburring.
Originality/value
The paper introduces an efficient robotic deburring method, which is developed based on a new active pneumatic tool, considers the interaction among the tool, the manipulator, and the workpiece, and couples the tool dynamics and a control design.

Abstract
Purpose
The purpose of this paper is to provide a review of the interdisciplinary research field, autonomous industrial mobile manipulation (AIMM), with an emphasis on physical implementations and applications.
Design/methodology/approach
Following an introduction to AIMM, this paper investigates the missing links and gaps between the research and developments efforts and the real‐world application requirements, in order to bring the AIMM technology from laboratories to manufacturing environments. The investigation is based on 12 general application requirements for robotics: sustainability, configuration, adaptation, autonomy, positioning, manipulation and grasping, robot‐robot interaction, human‐robot interaction, process quality, dependability, and physical properties.
Findings
The concise yet comprehensive review provides both researchers (academia) and practitioners (industry) with a quick and gentle overview of AIMM. Furthermore, the paper identifies key open issues and promising research directions to realize real‐world integration and maturation of the AIMM technology.
Originality/value
This paper reviews the interdisciplinary research field, autonomous industrial mobile manipulation (AIMM).

Abstract
Purpose
The purpose of this study has been to evaluate the technology of autonomous mobile manipulation in a real world industrial manufacturing environment. The objective has been to obtain experience in the integration with existing equipment and determine key challenges in maturing the technology to a level of readiness suitable for industry. Despite much research within the topic of industrial mobile manipulation, the technology has not yet found its way to the industry. To mature the technology to a level of readiness suitable for industry real-world experience is crucial. This paper reports from such a real-world industrial experiment with two mobile manipulators.
Design/methodology/approach
In the experiment, autonomous industrial mobile manipulators are integrated into the actual manufacturing environment of the pump manufacturer Grundfos. The two robots together solve the task of producing rotors; a task constituted by several sub-tasks ranging from logistics to complex assembly. With a total duration of 10 days, the experiment includes workspace adaptation, safety regulations, rapid robot instruction and running production.
Findings
With a setup time of less than one day, it was possible to program both robots to perform the production scenario in collaboration. Despite the success, the experiment clearly demonstrated several topics in need of further research before the technology can be made available to the industry: robustness and cycle time, safety investigations and possibly standardization, and robot and workstation re-configurability.
Originality/value
Despite the attention of research around the world, the topic of industrial mobile manipulation has only seen a limited number of real-world integrations. This work reports from a comprehensive integration into a real-world running production and thus reports on the key challenges identified from this integration.

Abstract
Purpose
The purpose of this paper is to present experience from a real‐world demonstration of autonomous industrial mobile manipulation (AIMM) based on the mobile manipulator “Little Helper” performing multiple part feeding at the pump manufacturer Grundfos A/S.
Design/methodology/approach
The necessary AIMM technologies exist at a mature level – the reason that no mobile manipulators have yet been implemented in industrial environments, is that research in the right applications have not been carried out. The paper proposes a pragmatic approach consisting of: a commercial‐off‐the‐shelf (COTS) mobile manipulator system design (“Little Helper”), a suitable and comprehensive industrial application (multiple part feeding), and a general implementation concept for industrial environments (the “Bartender Concept”).
Findings
Results from the three days of real‐world demonstration show that “Little Helper” is capable of successfully servicing four part feeders in three production cells using command signals from an Open Process Control (OPC) server. Furthermore, the paper presents future research and development suggestions for AIMM, which contributes to near‐term industrial maturation and implementation.
Originality/value
The paper presents a full‐scale demonstration of a state‐of‐the‐art COTS autonomous mobile manipulator system with particular focus on industrial utilization and application.

Abstract
Purpose
The aim of this paper is to integrate perception, action and symbolic knowledge to allow an autonomous robot to operate in unstructured environments and to interact with non‐expert users.
Design/methodology/approach
To achieve such goals, a cognitive robot architecture is proposed based on the integration between subsymbolic and linguistic computations through the introduction of an intermediate level of representation based on conceptual spaces.
Findings
The architecture has been tested in the CiceRobot project on tasks related to guided tours in the Archaeological Museum of Agrigento. Experimental results show that robot cognitive behaviors allow one to achieve a full functional robotic museum guide. In particular, through the interaction with visitors the robot is able to customize the tour depending on their preferences.
Originality/value
The paper presents a significant case study because it involves perception, planning and human‐robot interaction. The proposed architecture addresses the capacities which are generally addressed by an intelligent agent: the capability of representing itself and the external world, of imagining possible evolutions of the world, of paying attention to the relevant events, of planning and evaluating situations and actions.

Abstract
Purpose
Interaction with robot systems for the specification of manufacturing tasks needs to be simple since the paper targets the widespread use of robots in small and medium enterprises (SMEs). In the best case, existing practices from manual work could be used, to ensure current employees a smooth introduction to robot technology as a natural part of their work. The aim of the paper is to simplify the robot‐programming task by allowing the user to simply make technical drawings on a sheet of paper. Craftsmen use paper and raw sketches for several situations: to share ideas, to get a better perspective of the problem, or to remember the customer situation. Currently these sketches have to be either interpreted by the worker when producing the final product by hand, or transferred into CAD files using an appropriate software tool. The former means that no automation is included, the latter means extra work and considerable experience in using the CAD tool.
Design/methodology/approach
The approach is to use a digital pen and paper, both based on the Anoto technology, as input devices for SME robotic tasks, thereby creating simpler and more user‐friendly alternatives for the programming, parameterization and commanding actions. To this end, the basic technology has been investigated and fully working prototypes have been developed to explore the possibilities in the context of typical SME applications. Based on the encouraging experimental results, it is believed that drawings on digital paper will, among other means of human‐robot interaction, play an important role in manufacturing SMEs in the future. Consequently, a fully working test‐case welding example is presented and explained, allowing a complete demonstration of all the developed features.
Findings
This paper explores the utilization of digital pens for the task of programming industrial robot manipulators, i.e. the possibility of obtaining robot programs from technical drawings on a sheet of paper. A practical implementation was presented to demonstrate how to use digital pens and CAD applications to program industrial robots. The results clearly show that the digital pen based on Anoto technology, integrated with CAD interfaces and code generation interfaces, is very useful and powerful for the planned task. The next steps will be to adopt a software infrastructure and develop the necessary services to allow system integrators to consider this type of device as an advanced user‐friendly robot‐programming method.
Originality/value
This is the first time that digital pens have been used to program robot manipulators.

Abstract
Purpose
This paper aims to reveal how larger enterprises and small and medium-sized enterprises (SMEs) can enable innovation collaboration for enhanced competitiveness of the offshore wind energy sector.
Design/methodology/approach
The research is based on a longitudinal qualitative study starting in 2011 with a project-based network learning course with 15 SME wind farm suppliers and follow-up interviews with 10 SMEs and continued with interviews conducted with 20 individual enterprises within operation and maintenance conducted in 2014-2015.
Findings
The findings reveal challenges as well as opportunities for innovation collaboration between larger enterprises and SMEs to contribute to the innovation and competitiveness of the offshore wind farm sector. A glass ceiling is revealed for demand-driven positions if the SME does not possess rare and specific valuable knowledge. There are opportunities revealed in general for supplier-driven positions if SME suppliers can collaborate and develop interesting solutions for larger enterprises. If SMEs succeed in either of these aims, the SMEs have an opportunity to attain partner-driven collaboration. However, challenges are present according to the understanding of the different organisational approaches in SMEs and larger enterprises and in the different business approaches.
Research limitations/implications
The research is limited to the offshore wind energy sector. Further research is needed for verification of the findings in other energy sectors.
Originality/value
A fourfold contribution is made to enhance the understanding of innovation collaboration and to enable competitiveness for the offshore wind energy sector. SMEs, larger enterprises, academic researchers and policy bodies are provided with a model for action within the four positions for innovation collaboration.
