Leveraging Technology for a Sustainable World - Proceedings of the 19th CIRP Conference on Life Cycle Engineering | Year: 2012

This paper describes an approach to simulate the energy consumption of machine tools for a specific production task by modelling the energetic interactions of the machine tools' components and implementing the models in a simulation environment. By connecting a hardware machine control system with the simulation model, NC-code information is utilized and machine tool specific characteristics of the simulation model behaviour are achieved. Exemplarily, a specific machine tool is modelled and the energy consumption of a production process is simulated. The impact of the implementation of an improvement measure as well as the payback period of the investment is reviewed.

Leveraging Technology for a Sustainable World - Proceedings of the 19th CIRP Conference on Life Cycle Engineering | Year: 2012

In-process monitoring of the electrical power of manufacturing equipment has become technologically and economically viable and is essential in capturing the energy consumption behaviour of manufacturing systems in relation to operations. A concept for real-time analysis of electrical power, based on data stream analysis and event-driven system approaches has been developed and implemented as a software application. Electrical power data is handled in the form of streaming time series and are statistically analysed and transformed in compact, information rich representations in real-time. The developed prototype is validated on the example of a milling machine.

The problem of differentiating non-smooth functions of specimen displacements, which are measured during the material removal, is discussed. This problem arises when employing the layer removal method, namely a method of rings and strips, for residual stress depth profiling. It is shown that this problem is ill-posed and special solution methods are required in order to obtain a stable solution. The stability of the solution affects to a high extent the resulting accuracy of the residual stress evaluation in the investigated material. The presented study discusses a numerical approach to solving such ill-posed problems. The proposed approach, which is based on the Tikhonov regularization and a regularized finite difference method, provides a stable approximate solution, including its pointwise error estimation. The advantage of this approach is that it does not require any knowledge about the unknown exact solution; the pointwise error estimation of the measured data is the only prior information that must be available. In addition, this approach provides a convergence of the approximate solution to the unknown exact one when the perturbation of the initial data approaches zero. © 2016 Springer Science+Business Media Dordrecht

In this paper computational methodology of elasto-plastic states for rods subjected to thermal loads is presented. The dependence of stresses on strain was assumed on the basis of tension curves taking into account temperature. The computations of strains and stresses in a rod made of S235 steel, loaded by thermal fields generated by a point welding heat source of different intensities, were investigated. The analysis of development of plastic strains was carried out. Experimental tests were made for surfaced rod, with geometry and welding parameters assumed in numerical simulations, to verify the correctness of modelling. A simplified method was proposed to determine the longitudinal stresses in surfaced rods. © 2012 Elsevier B.V.

Technical Machine, a startup making a development boards for the internet of things, has launched a second generation product that has more power and better Wi-Fi. The Tessel 2 goes on sale today for $35 and will act more as a hub device mediating the inputs from a variety of sensors or other inputs. The board will ship in August. Jon McKay, the CEO of Technical Machine, said in a few weeks the company plans to launch a lower-power version of a Tessel 2 board that will function more like a sensor device. The idea of the board is to get web developers more accustomed to playing with code, comfortable taking their ideas for software and bringing them into the real world. With both Tessel boards they can now connect the web to a physical device — be it a sensor or something a bit more complicated like a display. McKay says companies such as Azure and SAP are using the boards in their data centers while other customers such as a doctor trying to prototype a wearable device and a company trying to increase insect protein production are also using the boards. The companies building prototypes are a big market for the Tessel 2 and one that McKay is trying to better serve with this iteration. McKay designed the board to make it easier and cheaper to take it into limited production of a hundred to a couple thousand items, such as making sure that unused sections of the boards can be broken off to avoid wasting space, you can integrate modules into the PCB so they the connectors or more secure. These efforts are part of several being attempted by companies in the burgeoning hardware sector to make manufacturing and prototyping easier. For example, when I covered the partnership between SnapEDA and Octopart I wrote: With the emergence of startups like the Toronto-based SnapEDA or the YCombinator startup Octopart, we’re seeing the evolution of hardware development that aims to be a bit more like software. Faster, more iterative and more responsive to the needs of a rapidly-changing marketplace. We won’t ever get to the speed of code, but it’s awesome to see the agility that’s common in software creeping its way into the hardware world as much as it can. With Tessel 2, programmers now can use these boards (currently they can program Tessel 2 in Node.js/io.js) to take their ideas for new hardware and turn them into reality without having to spent a lot of time learning a lot about hardware. The steps the Technical Machine team has taken to make getting prototypes to production easier means that the software developers using the boards get an even longer runway when it comes to learning about hardware. This will only help let good ideas mature a bit further and broaden the scope of what the internet of things will make possible. Technical Machine is backed by True Ventures, a venture capital firm that is an investor in the parent company of Gigaom.

Technical Machine (see disclosure) has raised $1 million in seed round funding led by True Ventures (see disclosure) with Slow Ventures and angels participating. The Boston-based startup was created this year and its founders are behind a nifty little project called Tessel, a board that basically lets developers who know JavaScript build connected devices. As a project, Tessel, which is a microcontroller that runs JavaScript, is interesting, but the concept behind the startup is an emerging trend. As Technical Machine’s Kelsey Breseman explains, the goal is to make it easy for web developers to play around with the internet of things. As someone who uses If This then That (IFTTT) as a way to combine the talents and services built by web developers with my connected gadgets, I am a huge believer in this concept. Others are too. Chris Matthieu, a manager in the Emerging Technologies section at Bechtel, has built a project called Skynet, that lets people build and see connected devices on a network using Node.js. He calls it IM for the internet of things. Other efforts, like Node Red from IBM, which offers people an easy interface for seeing how their devices connect, are also helping bridge the gap being the esoteric code for embedded systems and the Java-based languages that developers know and love. While Java is too “fat” to control the internet of things, new compilers and tweaks to the language or bridge devices are attempting to link the huge population of Java programmers with the growing population of connected devices. Others are even thinking about how this array of connected devices will change the back-end web development environment. Technical Machine is one example of a company trying to link developers and connected machines, and with Tessel the company had raised $196,682 from a crowd funding project. That money, plus this funding, will go toward producing the board, but also figuring out the right business model and method to support developers. For example, if someone uses Tessel to build a product, like a digital photo frame that shows photos you tag with a special code in Dropbox, that would be amazing. (That really would be amazing. Can someone get on that?) But after someone built this photo frame, Technical Machine isn’t sure how to support the person. Does it create a Tindie-like store to help developers sell their connected wares? Does it produce the connected products for the developer? Does it create an ecosystem ti help them find manufacturing? These are questions Technical Machine and others are trying to solve. For example, Joe Heitzeberg, a co-founder of the Poppy 3D glasses, is also asking these questions and looking for an answer. We chatted over the summer and afterward I wrote: …we discussed how to build a lasting business around the hardware movement. That’s what they are trying to do with their company Hack Things. In many cases, Poppy is their attempt to learn the ropes and gain some street cred when it comes to building physical goods. And sure, it may be a wild success, or even just a mild success, but the two are thinking bigger. “We’re thinking about how to make a guild for the hardware movement,” said Heitzeberg while Lowry described it as an equivalent of the graphical user interface for computers for hardware developers. This might sound a bit esoteric, but it’s important. The two are trying to figure out how to codify and automate the processes around building a product. So Technical Machine and others trying to link web developers to the once-rarified world of physical hardware and embedded systems are one aspect of the problem. The next will then be how to create a real and scalable business from their inventions. There are many entities trying to solve one of these two problems, and as the year progresses I think we’ll see even more. The question is who will figure out what the right business models are and then start creating a software stack and the fulfillment model for building out connected hardware.

Imagine a home speaker system that identifies everyone in the room and plays only the music they wanna hear. Tapping into tiny RFID chips installed on people’s cell phones, this system would pinpoint each person’s Facebook profile, parse their music tastes by way of the streaming music service Spotify, and create a playlist on the fly. And as new people enter the room and others leave it, the system would adjust this playlist accordingly. What you imagine is here today. Tim Ryan and a team of four other engineering students built such a contraption last year, as part of their senior capstone project at Olin College in Massachusetts, and if you like, you can build one too. Ryan and his team didn’t just create a new-age speaker system. They created a collection of hardware and software that let anyone build all sorts of physical devices that interact with the people around them. “We wanted to create a platform for building socially connected machines,” Ryan says. The core of their project is a custom-designed circuit board called the Tessel, and they’ve now “open sourced” the board’s designs — made them free for anyone to use — giving people everywhere the power to fashion their own Tessel boards and use it as the basis for whatever new-age contraption they like. Meanwhile, Ryan and his colleagues have formed a company, called Technical Machine, that will steward the open source project and help others build their contraptions. Technical Machine sits at the intersection of two major technology trends. One is the “quantified self” movement — where people collect and analyze data describing their themselves and their habits by way of health trackers like the Fitbit, productivity trackers like RescueTime, and music applications like The other is the “internet of things” — where our everyday world is reshaped by all sorts of web-connected devices, such as the Nest Labs thermostat system and the Phillips Hue home lighting control system. Quantified self expert Chris Dancy calls this intersection “existence as a platform” — and Technical Machine wants to be the company that builds that platform. Ryan and crew built Tessel because they thought building a personalized, web-connected speaker system should be easier than it was. So many public web services now offer tools called APIs, or application programming interfaces, that make it easier for anyone to build other software and services. APIs make it easier to, say, build an application that combines data from both Facebook and Spotify — and many other applications. Even non-developers can get in on the action through services like IFTTT — short for “If This, Then That” — which makes it easy to connect different services without writing code. But physically building hardware that connects to such web services is still challenging. It’s not that open source hardware hasn’t come a long way in recent years. It has. The open source microcontroller called the Arduino and the dirt cheap, credit card-sized computer called the Raspberry Pi have put hardware hacking within the reach of more hobbyists and entrepreneurs than ever. From Linux-powered beer fermentation systems to sensor networks for restaurants and greenhouses, we’re seeing a renaissance in connected devices. But Ryan and company found a gap in the hackable hardware market when they started building devices. Connecting the Arduino to a wireless network was a pain. They had to find a wireless module, solder it, and customize the firmware. Once it was working, they found that the Arduino didn’t pack the computational punch required to handle much web traffic. The Raspberry Pi, on the other hand, felt like overkill. They didn’t need or want a full Linux computer. The team was able to cobble something together that worked, but the experience left a lot to be desired. “Where it got really tough was trying to write documentation,” says Ryan. It was hard to explain all the hardware stuff in a way that web developers would understand, and it was hard to explain all the web development stuff in a way that hardware engineers would understand. Ultimately, the team decided they didn’t want to teach web developers about hardware. They want to teach hardware people about developers. Ultimately, the team decided they didn’t want to teach web developers about hardware. They want to teach hardware people about developers. The result is Tessel. It’s a board more powerful than the Arduino, and it’s specifically designed for web connected applications. More importantly, it’s built specially for people who build such web applications. To that end, Tessel runs a custom firmware system that can run JavaScript, letting web developers use a language they already know, and take advantage of the wide range of re-usable open source code built for the popular JavaScript platform called Node.js. “Through Node.js you get web servers and libraries right out of the box,” Ryan says. Eventually, they want to support more languages than just JavaScript. There’s no need to install and configure Linux or any other operating system. The firmware can just run the code as is. Ryan compares it to internet services like Heroku, which make it possible for web developers to run code in the cloud without needing to worry about configuring and managing computer servers. “Tessel is like Heroku for physical things,” he says. It’s also a platform for running additional hardware. Its modular setup lets developers add additional components to the board without soldering. The company has already designed 11 of these modules, including an accelerometer, a GPS tool, and sensors for detecting things like humidity, temperature, and light. But it has also published documentation so that third parties can design and build their own modules. Although Technical Machine has published its designs, there are no Tessels “in the wild” — at least not yet. But the company raised over $180,000 in a crowd-funding campaign and hope to start shipping the boards in mid-November. That home speaker system you imagine isn’t as far away as you think.

Building on the success of its flagship product Tessel, released last May, Technical Machine is introducing Tessel 2, an enterprise-grade embedded hardware platform that enables software developers to easily create Web-connected devices, including everything from Internet-enabled manufacturing equipment to self-watering plants. “We’ve seen a ton of interest from engineers outside the traditional embedded industry who want to build products with a hardware component,” said Jon McKay, co-founder of Technical Machine. “Prototyping tools such as Tessel have been getting easier to use but scaling a product is still really difficult. Tessel 2 enables this quickly growing user base to start scaling hardware products even without electrical engineering expertise, and without investing the time and cost you might need with traditional processes like consulting shops.” Founded in September 2013, Technical Machine raised nearly $200,000, almost four times its original goal of $50,000, through an online crowdfunding campaign in October 2013. The following month, the company secured more than $1M in a funding round led by True Ventures. Technical Machine sold thousands of original Tessel units to customers that include SAP, Microsoft, and Intuit. “We see a huge untapped market for all kinds of ‘Internet of Things’ goods,” said Rohit Sharma, venture partner with True Ventures, the company’s lead investor. “The challenge is that Web developers can write the code to run those items, but lack the electrical engineering expertise to build the hardware. The Tessel platform makes it easy for entrepreneurial Web developers to create connected devices inexpensively and efficiently, and Tessel 2 lets them take those devices into production.” Tessel 2, less than half the cost of its predecessor at volume, is designed to be embeddable at scale. It offers the ability to only populate parts of the board that are needed, and to integrate Tessel Modules into the circuit board instead of using connectors. The result is a cost-effective, integrated printed circuit board that enables customers to get to market faster and cheaper than ever before. Tessel 2 features robust built-in Wifi and a completely compatible Node.js/io.JS runtime. Tens of thousands of Node software libraries can be used out of the box. Tessel 2 uses plug-and-play hardware modules including temperature sensors, cameras, and servo motors, etc. The team plans to support Rust and other languages soon after ship. Analysts expect interest and demand for Web-enabled devices to skyrocket during the next few years: Gartner estimates 26 billion devices will be created by 2020. What’s more, 62 percent of SMBs say they’ve dedicated budget to develop Internet of Things products this year. “With its open and scalable platform for hardware development, Technical Machine is positioned to help drive and support business growth and creation as more companies push to develop these web-connected devices,” added Sharma from True Ventures. In addition to McKay, Technical Machine’s co-founders are Tim Ryan, Chief Product Officer, and Jia Huang, Chief Operations Officer. Customers can pre-order V2 Tessel here for $35, and less at scale. Shipping is slated for August 2015.
