“…Within the field of adaptive robotics, there are a range of approaches from projects such as: towards visual feedback loops for robot-controlled additive manufacturing, where the robot programming reacts adaptively to unpredictable material and environment (Sutjipto et al 2019) to more general changes in the fabrication paradigm. The project: on the relationship of multi-agent algorithms and robotic fabrication is such an example, where the robot is used as a design agent more as just a tool (Snooks and Jahn 2016).…”

Additive manufacturing enables industries with a new production typology. For the metal manufacturing industry, this new means of production extends the spectrum of achievable building parts that can be fabricated and integrated into architectural designs. Consequently, this process is becoming increasingly relevant for construction industries. The application of additive manufacturing in metal fabrication industries requires high performance technology and extensive knowledge of material and process. Within this paper, we focus on the implementation of incremental point welding as a metal additive arc welding strategy. The goal is the realization and optimization of a manufacturing method which implements adaptive strategies in the control of this production process. In this research, incremental point welding is used for the production of branching structures. Incremental point welding is a type of metal arc additive manufacturing which deposits material by adding individual welding points rather than layering welding seams. This process is interesting for a number of reasons. The incremental application of individual metal drops simplifies the analysis and forecast of residual stress and temperature developments. Consistent arc initialization within point welding is hard to control and, therefore, requires further exploration. This led to the following research in developing an adaptive process. Furthermore, the potential of the process is increased by the possibility of tool-path adaptivity for a robotic system enabling the robot to produce welds at complex approach angles. This research developed a novel approach, able to manufacture complex branching structures while compensating for inaccuracies caused by the welding process using image processing and an adaptive strategy. First experiments showed the possibility to work at a range of overhang angle in addition to multiple approach angles up to 50°. This adaptive process increases the potential application of this technology for the extensions of existing structures as well as repair of metal structures through incremental point welding.

The disconnection between architectural form and materiality has become an important issue in recent years. Architectural form is mainly decided by the designer, while material data is often treated as an afterthought which doesn’t factor in decision-making directly. This study proposes a new, real-time scanning-modeling system for computational design and autonomous robotic construction. By using cameras to scan the raw materials, this system would get related data and build 3D models in real time. These data would be used by a computer to calculate rational outcomes and help a robot make decisions about its construction paths and methods. The result of an application pavilion shows that data of raw materials, architectural design, and robotic construction can be integrated into a digital chain. The method and gain of the material-oriented design approach are discussed and future research on using different source materials is laid out.

“…Zhang et al ( 2018 ) constructed a 3D printing system that employs multiple mobile robots printing a large, single-piece, structure concurrently. Snooks and Jahn ( 2018 ) discussed relationships between multi-agent algorithms and robotic fabrication focusing on feedback between material behavior and robotic operations. We can evolve robots that can solve tasks by creating physical objects online, and such objects can be a scaffold for solving the tasks more easily.…”

Evolution of Complex Niche-Constructing Behaviors and Ecological Inheritance of Adaptive Structures in a Physically Grounded Environment

Niche construction is a process in which organisms modify the selection pressures on themselves and others through their ecological activities, and ecological inheritance is the consequence of niche construction inherited through generations. However, it is still unclear how such mutual interactions between robots or embodied agents and their physical environments can yield complex and divergent evolutionary processes or an open-ended evolution. Our purpose is to clarify what kind of complex and various niche-constructing behaviors evolve in a physically grounded environment under various conditions of ecological inheritance of constructed structures and spatial relationships. We focus on a predator-prey relationship, and constructed an evolutionary model in which a prey creature has to avoid predation through the construction of a structure composed of objects in a 2D physically simulated environment supported by a physics engine. We used a deep auto-encoder to extract the defining feature of adaptive structures automatically. The results in the case of no ecological inheritance revealed that the number of available resources can affect the diversity of emerging adaptive structures. Also, in the case with ecological inheritance, it was found that combinations of two types of ecological inheritance, which are the inheritance of adaptive structures and birthplace, can have strong effects on the diversity of emerging structures and the adaptivity of the population. We expect that findings in evolutionary simulations of niche-constructing behavior might contribute to evolutionary design of robotic builders or robot fabrication, especially when we assume physically simulated environments.
