A LIFETIME OF SUMMERS | WITH NIKE SAVVAS & UAP

A Lifetime of Endless Summers from below

There is a dusting of jolly confetti falling gracefully from the ceiling of The Exchange, Sydney, the spiralling, light-filled hive, commissioned by Lendlease Australia, and designed by Kengo Kuma & Associates. A Lifetime of Endless Summers by renowned artist Nike Savvas, cascades in shades of yellow, orange, pink, green, and blue, capturing the wind, coaxing the harbour breeze indoors. In order to deliver this piece, in collaboration with Savvas, Urban Art Projects (UAP) experimented with interaction design using Augmented Reality (AR) and Virtual Reality (VR) technology.

Interaction Design (Wind)

The freedom to explore and experiment consistently drove this project forward, into new and unexpected territory, not least because this was a complex and varied piece. The artwork covers a 12-metre diametre and comprises 9,200 aluminium tabs finished in numerous fluorescent paint finishes. Each component was suspended via a system of 715 ultra-fine wire cables that fixed directly into the ceiling.
Once Savvas and Lendlease reached a consensus regarding the immersive experience, wind testing was employed at the UAP’s Brisbane foundry.  In fabrication, the team determined the precise spacing requirements. This involved regulating clear gaps to prevent individual wire drops from getting knotted and twisted. This kind of optimised precision enabled each wire drop to gently oscillate, delivering a range of sensations via an interplay between gentle breezes and the kinetic field of colour.
In production, the aluminium components were carefully designed and mounted to sway at random angles between an approximate range of 0-45 degrees. Each wire was placed at a minimum midpoint of 300 millimetres, with an extra 600-gram weight appended at the end to ensure just the right amount of gravity and sway.

AR & VR Solutions

The piece was successfully delivered using AR HoloLens headsets and Fologram VR mixed-reality software to manage the complexities of the installation on-site; a process that flawlessly encapsulates Savvas’ sense of playful ingenuity, and UAP’s commitment to delivering cutting-edge solutions built on a combination of value-added processes and technological innovation.
UAP also employed these tried and tested AR and VR technologies during the documentation and installation stage. This allowed the installation team to move freely, whilst skillfully navigating and visualizing each focal point via a direct overlay of digital elements amidst what already existed in the physical world.
Using Hologram and Fologram allowed UAP’s craft makers to execute the exact placement of the drill holes. The same holes were then carefully matched with the suspended wire drops and ceiling trays, which sat over-and-above a circular ceiling between the market hall and mezzanine restaurant. All those involved across the process remain extremely positive and enthusiastic about their experience and its impact on the outcome. Seamlessly combining AR and VR construction not only made for a safer work environment but saved days of time, opening up opportunities to integrate human creativity and intuition into the process.
Advanced manufacturing systems and technologies helped reduce the occurrence of human errors, which reduced the risks and costs traditionally involved in bespoke design and construction. As such, the use of Fologram and HoloLens delivered continuous engagement, and the opportunity to expand the scope of vision systems in design-led manufacturing.

Delivering Bespoke Outcomes

As in many industries, technological advances and human artistry in manufacturing and design are converging. Whilst some fear that automation will kill jobs, Design Robotics and UAP recognise the important role technological advances play in supporting skilled workers. Human/robot interaction not only assists in the completion of tedious and repetitive tasks but also reduces risk. In this context, human partners are free to explore creative tasks, which has a direct impact on productivity and wellbeing.
Via the support of the Innovative Manufacturing Cooperative Research Centre (IMCRC), Design Robotics and UAP have partnered to present a range of new possibilities. The goal is simple – to design for human intelligence and optimize the relationship between people and machines. Watch this space as Design Robotics and UAP are committed to operating at the forefront of novel solutions, meshing technology with human creativity to explore a myriad of new possibilities.
A Lifetime of Summers launches a long-term commitment to robotic vision systems and software user-interfaces that enhance and support skilled workers. Associate Professor Dr. Glenda Caldwell, Cheif Investigator, Design Robotics described the process as “…the opportunity to work collaboratively with robotic technologies to decrease human risk in manufacturing and increase innovation and creativity”.
Reimagining the design process and pushing boundaries in industrial robotic capabilities empowers people to navigate increasing workplace complexity. At its heart, this work identifies what robots and machines do best – problem-solving, and matches it with what humans do best – social intelligence and contextual understanding. This symbiosis creates resilient outcomes, and enhanced processes, firmly placing Australia at the forefront of innovation and enterprise.

Entering the artwork
The Concept of Freedom

Thanks to collaborative partnerships, like Design Robotics and UAP, embracing technology ensures value-added mass customization. With an eye on addressing logistical complexities, solving engineering challenges, and meeting tight deadlines. In this context, artists, like Savvas, can focus their attention on creative potential. This not only informs the work of the Design Robotics team but fosters a culture of cross-germination and skills acquisition, which impacts UAP’s crafts makers and the manufacturing sector Australia-wide, and internationally.
On one hand, A Lifetime of Summers is playful, teasing the vibrant kinesis between form, wind, and colour. Equally, it is profound in the pursuit of meaning. By simply standing beneath it, viewers are transported into a hypnotic trance, revelling and reflecting whilst charmed by a sense of freedom and the optimism of endless summers. Yet, few will appreciate the cutting-edge approaches that were applied in its making – that’s our little secret.

REVIEW | ARCHITECTURAL ROBOTICS

Over the past 15 years, researchers in architecture and construction have been exploring the possibilities of employing industrial robotic arms (IRA) to help create new kinds of architectural forms. There is now a wealth of research in this area that manufacturers can draw upon to inform advanced manufacturing processes, due to the power that they entail in the direct path from digital design to fabrication. For architects, designers and construction managers, this research also points the way to new design possibilities.
In the scope of this training material, examples from current architectural and design research are explored. Recent publications from ROBArchCuminCAD and prominent universities were analysed to identify key design methodologies. The key findings of the literature review show that there is a need for a paradigm shift in the way fabrication is thought, as the design methods used in the early exploratory stages directly correlates with the way the industrial robots function and manufacture.

With the use of IRAs in architecture, designers have the possibility to fabricate their designs directly from the parametric digital design tools that they use. This direct connection between design and fabrication creates a fundamental shift in the way we perceive design, as architects. Suddenly, we are in control of the whole process of making; from material behaviour to structural rigidity, from material optimization to cost effectiveness, from sustainability to innovative techniques. Similar to the idea of sketching, the making process becomes more iterative, fluid and directly connected to our minds. It is also more playful and unique to our personal experiences (erlebnis).
Some of the design methodologies that arise from the exploration of IRA’s usage in architectural fabrications can be named as drawing, folding, 3D printing, deforming, stacking, weaving and carving. One might understand that each one of these methodologies are related to words of action, as they entail making in their existence. Most of the examples that are discussed in this section are pioneering exemplars that open up novel ways of making. Still at their early stages of exploration, these exemplars will change the way of architectural fabrication.

3D Printing

3D Printing technologies have been available to architects since the early 90’s, however, they are confined with the dimensions, the limitations and the available materials of the 3D Printers. With the use of IRAs, the possibilities of printing bigger and customised solutions became possible. Depending on the material used for printing, the outcomes could be real-time constructed structures without curing / assembling times. Also explorations into customised materials with sustainability considerations can be tested. Materials like recycled plastics, acrylic, nylon, resin, wood metal, rubber, salt, cement, sand, etc… can be used for 3D printing possibilities.
In the work of “Aggregation” by ICD, the concept of 3D printing is explored through a different kind of material compared to current 3D printing material. Instead of using a filament, this project uses a 3D elemental piece to be poured by an IRA. Through gravitational force, the material entangles to one another through a natural flow and compresses naturally. This process creates new ways of constructing through an aggregation process. There are no binders, no curing times. Allowing structure to emerge instantaneously through the process of pouring.
In the work of “Robotic Welding the Bridge” by MX3D, IRAs demonstrate the ability to 3D print in stainless steel. 3D printing is achieved by welding IREs. Welded forms have a lot of flexibility in relation to creating complex geometries and force distribution. More explorations with fluid materials that are more similar to 3D printers as we know it are the works of Roland SnooksEmerging Objects and AI Build.

Deforming

Deforming a rigid material using material’s physical properties creates novel uses of that material. In architecture, deforming through vacuum forming has been used for creating repetitive elements through metal and plastic sheets moulds in many design projects. However, the idea of mass-customisation through parametric design suggests novel techniques for fabrication with this technique. As, custom designed panels require custom moulds, cost and precision becomes the main concerns for manufacturers. In order for custom moulds to be sustainable and economically feasible, manufacturing speed, recycling and accuracy should be taken into consideration. With their speed and precision, IRAs can apply adequate force to create exact deformations in metal sheets to achieve high quality results. [Kalo, A. & Newsum, M. J. (2014)]

Folding

The folding techniques used in architecture are mainly influenced by the folding techniques from Japanese Origami art. In the Origami technique, a planar paper surface is folded into 3dimensional geometries without losing material. The folds create rigidity in the material in a way that it is possible to resist gravitational forces as well as lateral forces. Similar ideas of Origami are tested and prototyped in the manufacturing process of Robofold. In the explorations of Robofold, laser cut aluminium plates that have scores of folding as well as joint holes, which are folded by three IREs applying equal forces.

Stacking

Stacking materials is a repetitive and tiring process that requires optimisation, attention, precision and equal force distribution. The significance in the process of stacking is in the overall algorithm that defines the rules of stacking in relation to each piece with one another, that requires real-time feedback loops, using vision sensors. In architectural fabrication, stacking materials by using pick and place functions in IRAs is commonly used. Pioneering research group, Gramazio Kohler explore the potential of such technologies through onsite robotic construction.

Weaving

Inherent in our nomadic existence, weaving has been an integral part of architectural fabrication. Roof structures, partition elements have been woven using various materials since centuries. However, today with the use of IRAs in digital design to fabrication, architects realized a new potential in this way of fabrication. In the works of ICD, New materials such as carbon fibre have initiated unforeseen potentials in the making of spaces, using biomimetic approaches to design. Parasitic structures as well as self-standing
lightweight structures enable fast and clean on-site fabrication of lightweight structures. Either constructed as elemental units, or parasitical structures that are weaved into localities, weaved elements create their own structural integrity, allowing adequate weight distribution and optimised material use. Some weaved structures allow human-robot collaboration by humans assembling infrastructures for robots to weave, or humans assembling robotically weaved elements into whole structures.

Carving

Carving has entered the world of architectural fabrication with 3 axis CNC’s. The flexibility of having a 6 axis IRA, allows multiple directional carving into materials. With the use of IRAs, using different end effectors, architects carve into materials with hotwire cutters as well as various milling tools. Using a hotwire cutter, QUT Design Robotics team has collaborated with UQ School of Architecture to create ROBOBLOX; a web to fabrication design process to cut custom designed patterns into sculptural friezes. Manufacturing company UAP uses robotic milling in creating custom mould patterns for bronze casting of bespoke artworks.

LINISHING | EXPLORING COLLABORATIVE ROBOTICS

Contemporary industrial production is no longer simply about reducing ergonomic and safety risks, or improving speed and productivity, more-and-more it is driven by decreasing lead-times and increasing levels of customisation. This approach requires flexible and adaptive production units, including a combination of human and robot capabilities. Here, we explore the role collaborative robots play in the linishing process.
Assistive Robots and machines that work alongside skilled human experts are key enabling technologies in advanced manufacturing and the factories of the future. Safety is a primary concern, but further work is needed to extend the application of robotic technologies across manufacturing environments. Rather than autonomous, robotic systems designed to replace human workers, new systems will work in areas requiring a high level of integration between human and robotic competencies.
Collaborative robots are robots designed to allow humans and robots to work together without the need for physical cells to separate and protect humans from the robot. These force-limited robots have built-in sensors that monitor and detect the presence of objects such as people by detecting impact and external forces. These robots stop moving when they impact with something else. They are also designed to have rounded edges and smoother finishes so that their impact creates minimal damage or harm to others.

Human and robot linishing collaboration

The linishing video of a UAP worker collaborating with a UR10 demonstrates the capability of a human and robot working together to achieve a time consuming and large scale task that would be difficult for a human to complete on their own.

Existing industrial robot installations are subject to strict international standards governing the design, installation, and integration of robots and robot systems (ISO 10218 1&2 – 2011).
There are four primary HRI safety methods. Methods often separate the robot and operator with physical or sensor-based barriers. Given these barriers are somewhat eliminated in collaborative workspaces the ISO standards have been updated to specifically address the integration of collaborative systems (ISO/TS 15066:2016). Collaborative robots employed to work in industrial operations must fulfil at least one of four modes. Different modes align with different applications of human/robot collaboration.

Digital Transformation

Advanced digital technologies have already transformed banking, communications, and media landscapes. Representing one-sixth of the global economy the manufacturing sector poses just as much potential for disruption.
Lower costs and improved robot capability are decreasing barriers to entry and increasing global competitiveness. From agriculture to transportation, SMEs are exploring robotic applications in areas not previously considered possible. Accordingly, 52% of Australian CEOs are exploring the possible benefits of humans and robots working together.

Core Considerations
  • End Effectors are the tools that can be attached to a robotic arm such
    as a gripper, a milling head, a spindle etc.
  • Payload is the weight that a robotic arm can carry. The payload needs to
    consider the weight of the end effector and anything it would carry or
    force it would apply.
  • Reach is the extension length of the robotic arm from its wrist to its base.
  • Maximum Speed is the fastest speed that the end effector can move.
  • Degrees of Freedom refers to the number of axes that the robotic arm can
    move around. The more degrees of freedom a robotic arm has means it has
    increased levels of dexterity.
  • Repeatability is the ability for the robotic arm to accurately repeat
    the same motion.
  • Price, Weight and Size are other factors that need to be considered when
    taking into account the different collaborative robots on the market.

Collaborative Robots that are force limited achieve their safe human/robot relationships through four different approaches. These different approaches classify the collaborative robots under 4 different types including:

  • Inherently Safe robots have many sensors and a low amount of force (a
    payload under 1kg) so even if they collided with a person they would not
    cause harm.
  • Skin Sensing robots use tactile sensing technology to sense impact
    causing them to stop automatically at specific levels.
  • Force Sensor Base robots have a force-sensor at their base which
    measures and detects different forces placed onto the robot.
  • Joint Sensing robots use their joints to detect and monitor forces that
    are applied to the robot’s body. This is the most common type of
    collaborative robot on the market and the one that the design robotics team
    at QUT uses for their research.

For more details and examples of different kinds of collaborative robotic arms made from a range of manufacturers refer to the comprehensive Robotiq Collaborative Robot eBook https://blog.robotiq.com/collaborative-robot-ebook.

Manufacturing Advantages
  • Improved cost-effectiveness in complex, creative tasks supporting approaches that let humans and robots collaborate effectively
  • Increased efficiency supporting co-located human/robot collaboration is expected to lead to significant time and cost savings
  • More flexibility Human/robot collaboration approaches allow for on-the-fly (or in-process) and direct designer input facilitating the creation of unique bespoke products for clients
  • Improved safety: Augmented Reality combined with human/robot collaboration enables increased scope for co-location of humans and robots supported by advanced safety mechanisms.
Manufacturing Limitations

Currently, the majority of collaborative robotic arms on the market have payloads under 16kgs which helps them be safer and easier to use in a range of applications. However, in many manufacturing tasks, there is a need for high levels of force to be applied by robotic arms to effectively achieve tasks such as metal polishing or grinding. Therefore one of the biggest limitations that collaborative robots face within manufacturing environments is their low levels of force that they can apply to work in industrial settings. Another limitation is their size with reach ranges typically under a meter, thus making it difficult for these types of robots to work on large or complex forms.
There are many ways that this can be overcome and will require each user to consider the pros and cons of the robotic technology available to them. As with many manufacturing processes, there is a workflow to consider which involves different skill sets, tools, and applications. Therefore some manufacturing settings may find they require a combination of traditional tools with industrial robots to conduct large high-force tasks which are then finished off by humans and collaborative robots to do the finer parts of the process. As with any process, the combination of tools and approaches will depend on several factors.\
