Drywall Installation & Masonry Installation…. by Robots

A while back ILMABlog did a series on Technology in Architecture & Construction.

More recently we just discovered the latest technology coming from Japan.  Researchers at Japan’s Advanced Industrial Science and Technology Institute have built HRP-5P, a humanoid bot prototype, reported Engadget.

The bot combines environmental detection, object recognition and careful movement planning to install drywall independently, including hoisting boards and fastening them with screwdrivers. To make up for its lack of movement compared to a human, HRP-5P has numerous joints that flex to degrees people are unable to. It also can correct for slips and is capable of fields of view beyond that of a human worker’s.

The team hopes to collaborate with private companies that will treat the bot as a development platform and lead to further breakthroughs. The robot is meant to tackle the “manual shortages” Japan is facing, AIST also posits, and will allow the limited pool of human workers to focus on lighter, less dangerous work.​

SAM100 is a bricklaying robot for onsite masonry construction. Designed to work with the mason, assisting with the repetitive and strenuous task of lifting and placing each brick. The mason will continue to own the site setup and final wall quality but will improve efficiency through the operation of SAM.

Robots Revolutionizing Architecture's Future 003

Robots are increasingly being utilized in everyday life to monitor and improve our environments. For example, Researchers from theNational University of Singapore have created a bevy of robotic swans that are designed to monitor the quality of freshwater lakes and reservoirs – such as levels of dissolved oxygen or chlorophyll – while blending in with the natural environment. The robotic birds, fitted with a number of sensors, autonomously swim across the water’s surface using underbody propellers.

Robots in Construction

At ETH Zurich, Gramazio & Kohler, an architectural partnership that is especially
known for its contribution to digital fabrication and robotic construction, taught at class
using a robot arm to lay bricks. This is the course as they describe it:

“If the basic manufacturing conditions of architecture shift from manual work to digital
fabrication, what design potential is there for one of the oldest and most widespread
architectural elements — the brick? Students investigated this question in a four-week
workshop, designing brick walls to be fabricated by an industrial robot. Unlike a mason,
the robot has the ability to position each individual brick in a different way without optical reference or measurement, i.e. without extra effort. To exploit this potential, the students developed algorithmic design tools that informed the bricks of their spatial disposition according to procedural logics. Positioning this way it was possible to draft a brick wall in which each of over 400 bricks took up a specific position and rotation in space. The students defined not the geometry of the wall, but the constructive logic according to which the material was organized in a particular temporal order, and which thus produced an architectonic form.”

Though robot arms are currently the most prevalent form of robotics in architecture,
architects and designers have begun to employ other, and sometimes more radical,
robotic strategies for design. Gramazio & Kohler, in collaboration with Raffaello
d’Andrea recently put together an exhibition titled ‘Flight Assembled Architecture’ for
which small quad-rotor helicopter bots assembled a 6m-tall and 3.5m wide tower out of
1500 polystyrene foam blocks in Orléans, France.

Robots Revolutionizing Architecture's Future 002

Walmart filed five more patents for farming processes

The patent was one of six filed by Walmart, including several focused on automating agricultural processes. The supermarket chain also plans to use drones for spraying pesticides and monitoring crop conditions.

However artificial pollination has the bigger potential to significantly affect the company’s business.

According to research by Greenpeace, pollination by bees contributes $265 billion to the global economy. So, with the world’s bee population now in major decline, robotic alternatives could prove necessary to meet the global demand for food production.

Walmart isn’t the first to have invested in artificial-pollination technology. Brisbane-based artist Michael Candy recently unveiled his design for a device featuring 3D-printed robotic flowers, while a research lab in Japan recently became the first to successfully achieve pollination using a drone.

Benefits of Using Digital Twins for Construction

Technologies like augmented reality in construction are emerging to digitalize the construction industry, making it significantly more effective.

What if we could have instant access to all the information about a construction site, down to smallest details about every person, tool, and bolt? What if we could always be sure about the final measurements of a beam or that soil volumes in the cuts are close to those of the fills? What if we could always track how fast the supply of materials runs out, and re-order supplies automatically?

All this is achievable with a digital twin — a concept of having a real-time digital representation of a physical object.

The following are some real-time digital twins applications on construction sites.

3d-model

Automated Progress Monitoring

Progress monitoring verifies that the completed work is consistent with plans and specifications. A physical site observation is needed in order to verify the reported percentage of work done and determine the stage of the project.

By reconstructing an as-built state of a building or structure we can compare it with an as-planned execution in BIM and take corresponding actions to correct any deviations. This is usually done by reconstructing geometry of a building and registering it to the model coordinate systems, which is later compared to an as-planned model on a shape and object level.

Often data for progress monitoring is collected through the field personnel and can be hugely subjective. For example, the reported percentage of work done can be faster in the beginning and much slower close to the end of the project. People are often initially more optimistic about their progress and the time needed to finish the job.

Hence, having automated means of data collection and comparison means that the resulting model to as-designed BIM models is less liable to human error. Digital twins solve the common construction process problems.

As-Built vs As-Designed Models

With a real-time digital twins, it is possible to track changes in an as-built model — daily and hourly. Early detection of any discrepancies can lead to a detailed analysis of historical modeling data, which adds an additional layer of information for any further decision-making processes.

The project manager can then reconstruct the steps that led to the error and make changes in the future work schedule in order to prevent any similar mistakes from occurring. They can also detect under-performers and try to fix the cause of the problem earlier in the project or plan the necessary changes to the budget and timescale of the whole project.

Resource Planning and Logistics

According to the Construction Industry Institute, about 25% of productive time is wasted on unnecessary movement and handling of materials.

Digital twin technology provides automatic resource allocation monitoring and waste tracking, allowing for a predictive and lean approach to resource management. With digital twin technology companies would avoid over-allocation and dynamically predict resource requirements on construction sites, thus avoiding the need to move resources over long distances and improving time management.

Safety Monitoring

The construction industry is one of the most dangerous sectors in the world. According to the Bureau of Labor Statistics in the United States, more than four thousand construction workers died on-site between 2008 and 2012.

The real-time site reconstruction feature digital twins allows the industry’s companies to track people and hazardous places on a site, so as to prevent inappropriate behavior, usage of unsafe materials, and activity in hazardous zones. A company can develop a system of early notification, letting a construction manager know when a field worker is located in dangerous proximity to working equipment and sending a notification about nearby danger to a worker’s wearable device.

Microsoft recently shared a great vision of how AI combined with video cameras and mobile devices can be used to build an extensive safety net for the workplace.

Quality Assessment

Image-processing algorithms make it possible to check the condition of concrete through a video or photographic image. It is also possible to check for cracks on columns or any material displacement at a construction site. This would trigger additional inspections and thus help to detect possible problems early on.

See an example of how 2D images using 3D scene reconstruction can be used for concrete crack assessments.

Optimization of Equipment Usage

Equipment utilization is an important metric that construction firms always want to maximize. Unused machines should be released earlier to the pool so others can use them on other sites where they are needed. With advanced imaging and automatic tracking, it is possible to know how many times each piece of machinery has been used, at what part of the construction site, and on what type of the job.

Monitoring and Tracking of Workers

Some countries impose tough regulations on how to monitor people presence on a construction site. This includes having a digital record of all personnel and their location within the site, so that this information could be used by rescue teams in case of emergency. This monitoring is another digital twins application. Still, it is better to integrate digital twin-based monitoring with an automatic entry and exit registration system, to have a multi-modal data fused into a single analytics system.

Getting Data for Digital Twins

Some ways to gather data to be used for digital twins includes the following:

  1. Smartphone Cameras
  2. Time-Lapse Cameras
  3. Autonomous UAV and Robots
  4. Video Surveillance Cameras
  5. Head-mounted Cameras and Body Cameras

Image data processing algorithms for digital twins can be created with the following methods:

  1. 3D Reconstruction: Conventional Photogrammetry
  2. 3D Reconstruction: Structure from Motion
  3. Object Detection and Recognition
  4. Localization
  5. Object Tracking

From an Investor’s Viewpoint

On projects to date, this approach has proven to save time, reduce waste and increase efficiencies.

From a Standardization Proponent’s Viewpoint

Open, sharable information unlocks more efficient, transparent and collaborative ways of working throughout the entire life-cycle of buildings and infrastructure.

From a Solution Provider’s Viewpoint 

While the digital twin is needed initially for planning and construction, it’s also intended to provide the basis for building operations moving forward.

The vision of “construction 4.0” refers to the 4th industrial revolution and is a fundamental challenge for the construction industry. In terms of automated production and level of digitalization, the construction industry is still significantly behind other industries. Nevertheless, the mega-trends like Big Data or the Internet of Things offer great opportunities for the future development of the construction sector. Prerequisite for the successful Construction 4.0 is the creation of a digital twin of a building. Building Information Modeling (BIM) with a consistent and structured data management is the key to generate such a digital building whose dynamic performance can be studied by building simulation tools for a variety of different boundary conditions.

Along the total life cycle from design to construction, operation and maintenance towards remodeling or demolition, the digital twin follows all modifications of the real building and dynamically readjusts itself in case of recorded performance differences.

Thus, for the whole life span of the real building, performance predictions generated with the virtual twin represent an accurate basis for well-informed decisions. This helps to develop cost-effective operation modes, e.g. by introducing new cyber-controlled HVAC systems. The digital twin may also analyze the building’s dynamic response to changes in occupation or energy supply; it also indicates the need for building maintenance or upgrades.

The digital twin follows all modifications of the real building and dynamically readjusts itself in case of recorded performance differences.
