Real-Time Kinematics Coordinated Swarm Robotics for Construction 3D Printing
1 Real-time Kinematics Coordinated Swarm Robotics for Construction 3D Printing Darren Wang and Robert Zhu, John Jay High School Abstract Architectural advancements in housing are limited by traditional construction techniques. Construction 3D printing introduces freedom in design that can lead to drastic improvements in building quality, resource efficiency, and cost. Designs for current construction 3D printers have limited build volume and at the scale needed for printing houses, transportation and setup become issues. We propose a swarm robotics-based construction 3D printing system that bypasses all these issues. A central computer will coordinate the movement and actions of a swarm of robots which are each capable of extruding concrete in a programmable path and navigating on both the ground and the structure. The central computer will create paths for each robot to follow by processing the G-code obtained from slicing a CAD model of the intended structure. The robots will use readings from real-time kinematics (RTK) modules to keep themselves on their designated paths. Our goal for this semester is to create a single functioning unit of the swarm and to develop a system for coordinating its movement and actions. Problem Traditional concrete construction is costly, has substantial environmental impact, and limits freedom in design. In traditional concrete construction, workers use special molds called forms to shape concrete. Over a third of the construction cost of a concrete house stems from the formwork alone. Concrete manufacturing and construction are responsible for 6% – 8% of CO2 emissions as well as 10% of energy usage in the world. Many buildings use more concrete than necessary, and this stems from the fact that formwork construction requires walls, floors, and beams to be solid. -

Building 3D-Structures with an Intelligent Robot Swarm
BUILDING 3D-STRUCTURES WITH AN INTELLIGENT ROBOT SWARM A Dissertation Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Master of Science by Yiwen Hua May 2018 c 2018 Yiwen Hua ALL RIGHTS RESERVED BUILDING 3D-STRUCTURES WITH AN INTELLIGENT ROBOT SWARM Yiwen Hua, M.S. Cornell University 2018 This research is an extension to the TERMES system, a decentralized au- tonomous construction team composed of swarm robots building 2.5D struc- tures1, with custom-designed bricks. The work in this thesis concerns 1) im- proved mechanical design of the robots, 2) addition of heterogeneous building material, and 3) an extended algorithmic framework to use this material. In or- der to lower system cost and maintenance, the TERMES robot is redesigned for manufacturing in low-end 3D printers and the new drive train, including motor adapters and pulleys, is based on 3D printed components instead of machined aluminum. The work further extends the original system by enabling construc- tion of 3D structures without added hardware complexity in the robots. To do this, we introduce a reusable, spring-loaded expandable brick which can be eas- ily manufactured through one-step casting and which complies with the origi- nal robots and bricks. This thesis also introduces a decentralized construction algorithm that permits an arbitrary number of robots to build overhangs over convex cavities. To enable timely completion of large-scale structures, we also introduce a method by which to optimize the transition probabilities used by the robots to traverse the structure. -

The composites consist of semiconducting polymer nanowires dispersed in an insulating polymer matrix through a thermo- or photocuring process. The nanowires formed percolated networks for charge-carrier collection at a very low nanowire volume concentration. Photodetectors had been fabricated with such composites and obtained a low leakage current density of 25 nA cm−2, a large conductivity change of 18025 times upon light irradiation (1 sun), and a high specific detectivity of 4.5 × 1010 Jones. The composite precursors before curing had been used as paints on different surfaces including wood, cardboard, and glass fiber cloth to create photoactive coatings on these surfaces. The precursors had also been used for 3D printing to create photoactive structures with a mechanical modulus of 4 GPa and an ultimate strength of 36 MPa.

Remaking Creativity & Innovation: China's Nascent DIY Maker
Remaking Creativity & Innovation: China’s nascent DIY maker & hackerspace community Silvia Lindtner Post-doctoral Fellow Fudan University & University of California, Irvine [email protected] Paper Submission for the conference on: New Media and Cultural Transformation: Film, TV, Game, and Digital Communication School of Film-TV, Shanghai University New York University Shanghai Center December 7-9, 2012 In September 2010, China’s first hackerspace opened its doors in Shanghai under the name XinCheJian, (literal translation: new workshop, or new factory). Hackerspaces are shared studios that bring together people committed to the free and open sharing of software and hardware, as well as ideas and knowledge. As of April 2012, there are more than 500 active hackerspaces in existence worldwide, making them a global phenomenon1. A typical studio will be equipped with tools that allow for experimenting with the physical/digital boundary—laser cutters, 3-D printers, microcontroller kits, and so forth. Many hackerspaces also host educational workshops where these tools are used to teach others about manipulating the physical environment through software, or vice versa. The global hackerspace movement has helped proliferate a “maker culture” that revolves around both technological and social practices of creative play, peer production, a commitment to open source principles, and a curiosity about the inner workings of technology (Coleman 2012, Ratto 2007). Only a year after the founding of XinCheJian, the Shanghai government announced a call for proposals to build 100 “innovation houses” (chuangxin wu 创新屋) to be supported by 1 http://hackerspaces.org/wiki/List_of_ALL_Hacker_Spaces 1 government funding. Although the official document2 described this initiative as part of a larger effort to build a citywide platform for supporting popular science work and innovation, national and international media interpreted this move as an endorsement of China’s fledgling maker culture by Chinese politicians. -
Additive Manufacturing, Cloud-Based 3D Printing and Associated Services—Overview
Journal of Manufacturing and Materials Processing Review Additive Manufacturing, Cloud-Based 3D Printing and Associated Services—Overview Felix W. Baumann 1,2,* and Dieter Roller 2 1 TWT GmbH Science & Innovation, Stuttgart 70565, Germany 2 Institute of Computer-aided Product Development, University of Stuttgart, Stuttgart 70569, Germany; [email protected] * Correspondence: [email protected]; Tel.: +49-711-215-777-1207 Received: 22 September 2017; Accepted: 13 October 2017; Published: 17 October 2017 Abstract: Cloud Manufacturing (CM) is the concept of using manufacturing resources in a service-oriented way over the Internet. Recent developments in Additive Manufacturing (AM) are making it possible to utilise resources ad-hoc as replacements for traditional manufacturing resources in case of spontaneous problems in the established manufacturing processes. In order to be of use in these scenarios, the AM resources must adhere to a strict principle of transparency and service composition in adherence to the Cloud Computing (CC) paradigm. With this review, we provide an overview of CM, AM and relevant domains as well as presenting the historical development of scientific research in these fields, from 2002 to 2016. Part of this work is also a meta-review on the domain to further detail its development and structure. Keywords: additive manufacturing; cloud manufacturing; 3D printing service 1. Introduction Cloud Manufacturing (here CM, in other works also CMfg) as a concept is not new and has been executed in enterprises for many years [1], under different terms, e.g., Grid Manufacturing [2] or Agile Manufacturing [3]. The decision to have a globally distributed production process with many contractors or partners interconnected and related supply chains is a luxurious one. -

Press Contacts Marissa Lee Adobe Systems Incorporated 415-832-5378 [email protected] Reagan Crossley Edelman 650-762-2955 [email protected] FOR IMMEDIATE RELEASE Major Update to Adobe Photoshop CC Brings 3D Printing to the Design World First 2014 Creative Cloud Release Also Includes Amazing Perspective Warp Capability in Photoshop CC SAN JOSE, Calif., — January 16, 2014 — Adobe (Nasdaq:ADBE) today unveiled new 3D printing capabilities in Adobe® Photoshop® CC. By radically simplifying the 3D print process, Photoshop CC will become the go-to tool for anyone who wants to print a 3D model. Available immediately, as part of a major update to Adobe Creative Cloud™, the new 3D printing capabilities integrated in Photoshop CC enable Creative Cloud members to easily and reliably build, refine, preview, prepare and print 3D designs, setting the stage for explosive growth in the 3D printing market. The new 3D printing capabilities also help creatives to design in 3D from scratch or refine an existing 3D model and produce beautiful, print-ready 3D models using familiar Photoshop tools. Automated mesh repair and support structure generation ensure models will be produced reliably, while accurate previews allow creatives to submit print jobs with confidence. “The new 3D print capabilities in Photoshop CC take the guess work out of printing 3D models for everyone,” said Winston Hendrickson, vice president products, Creative Media Solutions, Adobe. “Before today there was a gap between the content produced by 3D modeling tools and what 3D printers need in order to deliver high quality results. Now, by simply clicking ‘Print’ in Photoshop CC, creatives can bring 3D designs to the physical world.” Photoshop CC Turbocharges Emerging 3D Print Ecosystem With today’s release of Photoshop CC, designs can be printed to a locally connected 3D printer or via built-in access to popular online 3D print services.
