Robotics and Intelligent Buildings
The required article gave a very in depth overview of robotics, ranging from the general idea and how different component were able to come together. I felt the article never went into current uses, applications and where robotics could eventually lead. I thought the sections on the different sensors that are used was interesting and allowed for one to come up with possible uses. I agree with what has been discussed by other students, that intelligent machines and robots will most certainly have a hand in the construction industry, however I don't see a time when they would be depended upon to construct the entire thing. I think the use of intelligent machines and robots in construction could very well grow with more and more pre-fab buildings, as the controlled environment of pre-fab construction would be ideal for robots.
Robotics Readings.
The second article I chose to read was "Scientists Developing Robotic Hand of the Future". It was about researchers in Spain developing a robotic hand to imitate a human's. This article I found particularly interesting because I like to see how close we are to actually imitating humans. I liked how this article was formatted because it stated the major problems faced by the researchers. This particular project is called HANDLE and is based out Carlos III University of Madrid. The researchers at this university are trying to figure out how humans manipulate objects in order to replicate the movement and sensibility and autonomous movement. This article identifies the main problems in recreating a human hand. Some of the problems are pretty simple. One for instance is the lack of space to fit all the components and sensors inside the actual robotic hand. Another problem is the sensor market place. The researchers can't find a sensor on the market that is small enough to fit in the hand and have the appropriate sensor capabilities. The last problem they faced is integrating an intelligent system incorporate autonomous movement as well as adaptations to the environment and object specifications.
These two articles directly relate to each other. the first article explains the different systems of the robot while the second article applies them to an actual project. The robotic hand uses the sensors and intelligent systems described in the Robotics article on Access Science.
Most students said the same thing as me when it comes to the assigned article. We mostly said it was a good overview of the robotics topic in general and was a good base for follow up article.
Robotics and Intelligent Construction
Emerging Construction Technology
Week 1 Post
Another item that is addressed is in the blog post "Robotics Reading" which discusses how robotics are useful for repeated tasks but are still greatly lacking in "complex and unique construction requirements." The author goes on to voice his skepticism over the construction industry becoming fully automated, which I will agree is will not happen for quite some time and I believe there will always be a need for people during the construction of a building even in the distant future, however I think there will be a time where robotics are responsible for upwards of 90% of the construction from start to finish.
Week 2: Robotics Readings
The assigned article is very technical and uses a lot of definitions. It does elaborate on the mechanics of robots and their configurations, and also does well to explain the kinematics and workings of robots, while detailing various components and types of robots. However, this article uses terminology that is likely better understood by engineers or researchers familiar with the field of robotics. The technical content is, therefore, a bit overwhelming. Overall, this article is also significantly more text-heavy than the other two articles I read, which focus more on applications of robots as interactive sensors for building architecture and engineering. This article delves into the details of how many types of robots work, providing a general overview of the field of robotics. The other two articles are more specific and explicitly state some of the uses of robotics in buildings, and their content assumes some familiarity with much of the content addressed in the assigned article. The second article I read relates the use of Local Positioning Systems (LPS) and Natural Feature Positioning Systems (NFPS) to the workings of satellite Global Positioning Systems (GPS) and its advanced use in robots used for collecting building space data and optimizing the temperature, energy, and air quality of a building, among other characteristics. The article also explicitly notes the usefulness of this technique to respond to emergency situations in a building and to communicate any sensed observations to a central building controls system. The article looks forward to the future of this application in buildings and states that further development has the potential to accomplish other useful tracking and recording features, such as sensing the conditions of building floors. This article aims to promote the idea of mapping devices revolutionizing their use in buildings. As this post also suggests, though this industry is focusing on the construction phase of buildings, ensuring the safety and maintenance of buildings is also a priority in this field and is also being continually developed.
The third article I read relates the use of robotics in architectural design. It focuses on the advantages that come with using fabrication robots, called ROB Units, to create prefabricated construction materials via algorithm programming. While the first article helps to define some of the qualities of the robot units discussed in the third article, the second article focuses on the maintenance of safety of buildings, as opposed to the importance and use of robotics in construction. This article also discusses the construction of a 72-foot structural wall made of bricks. This construction took place using preprogrammed units, but researchers in Zurich are looking into the ability of these robots to perform this type of construction while making “design decisions” simultaneously. This concept proposes a great potential in the field of robotics and its relation to building design and construction.
On Robotics and Intelligent Buildings
This brings me to my second issue. I was somewhat disappointed with the definition of robotics that the Access Science article seems to imply. Some of the language was over my head, but overall it was a good introduction to the main concepts and components of engineering. Still, the big picture that I got from reading the article is that the field of robotics is exclusively limitted to autonomously controlled or otherwise programed tools/objects that in some way resemble humans or perform human tasks. Most of the definitions you can find online offer the same explanation, and as humanoid technology continuous to improve, that window seems likely to narrow even further. As a civil engineer, I feel slighted by this concept of robotics. To me, a fully autonomous HVAC system, which analyzes data from sensors throught the building, and works in tandem with other building components to make necessary changes is as much a robotic accomplishment as getting a bipedal robot to walk forwards and backwards, mimicking human mechanics. A visual sensor which recognizes patterns in human behaviour, and uses that data to make comfort and safety decisions in your office building or home, is as much a robot as any other programmed device.
The first two articles I read go hand-in-hand and fit this expanded view of robotics, as well my thoughts on the need for smarter design and maintenance practices. Both articles are essentially transcripts from 2 of 3 summits which were held in Chicago, IL and Washington, DC, regarding the current state of smart, sustainable design in early 2011 (the 3rd was help in Los Angelos). The seminars brought together leading experts from IBM, Johnson Controls, Eaton and other major companies that have taken an interest in advancing green design. The first article provides quotes from these experts regarding current industry standards, classifications of a smart building, how these goals are being achieved now, and what future needs are. The second article discusses the same concepts, but focuses on how some LEED certified buildings are not performing adequately in their post-design life, by not living up to energy goals, or promoting as much employee productivity as owners were hoping for. The concerns raised here are that designing a building to meet LEED speficications is only the first achievement. After that, they must be managed by informed personel, who are able to make effective use of the available teechnologies and systems, in order to achieve efficiency goals. The two articles do not explicitly discuss any robotic applications or technologies, but they speak to the idea I brought up earlier, that this is the direction we need to go concerning the use of robots in the building industry. Also, looking ahead to the other discussion topics, I'm not sure if these articles would fit any better elsewhere.
Smarter Buildings: The Executive View, Part 1
Smarter Buildings, Part 2: How to Close Gaps Between Design and Performance
The third article gets much closer to the discussion topic, of robotic systems in building design, construction or usage. As the name suggests, the article discusses the potential usages of video cameras are building sensors. Currently, video cameras are used mostly to record footage of various locations in a building, which is monitor by security personel for safety purposes. For lack of a better term, I will call this a very passive application. The camera does nothing but record video; most of the decisions are still made based on human observation. The article brings up several analysis tools which can be coupled with typical video camera hardware to better integrate a buildings main systems. One of the coolest examples that is discussed is the use of person recognition technology, which can be used to count the number of people that enter and exit a building. If positioned at every entrance, this can provide an amazingly accurate occupancy reading, data which is otherwise difficult to monitor, yet is incredibly useful. Having those numbers, not to mention the ability to monitor it instantaneously could be integrated with HVAC systems to control the temperature settings in a room, operate lights, or make other decisions based on occupancy. Furthermore, pixel recognition can be used to spot fires or other safety and security issues much quicker than currently used sensors. Again, this article represents a unique technology that I feel is a better application of robotics to the building industry.
