“…The complexity of intermeshing states with different customer needs, functions, and conflicts makes successful transformer design an intimidating goal. Much research has been done on specific areas of transformation, such as robotics and space exploration [4,5], as well as flexible manufacturing processes [6]. Individual designers and companies have identified trends and use domain-specific design processes [7,8].…”

Products that transform into multiple states give access to greater flexibility and functionality in a single system. These “transformers” capture the imagination and can be elegant, compact, and convenient. Mechanical transformers are usually designed ad hoc; a methodology specifically aimed at creating transformation processes would help the designer better understand when to use transformation and how to best seize its advantages and avoid its pitfalls. There is an underlying common basis of principles and facilitators (e.g. Fold, Share Core Structure, Segment) that describes transformation processes. We conducted an empirical study of 190 reconfigurable products across several domains, observing the overall trends in how transformation occurs. We confirmed the consistent use of similar principles and facilitators across the design space, and we quantitatively determined the extent of correlation among them. This paper lays out characteristics and interactions that are popular in current transformer design, as well as opportunities for innovation in new directions. A case study is also presented that illustrates how these results can be used in the future to help develop a step-by-step methodology for generating concepts of transforming products.

“…In response to the evolving demands across various domains, including those posed by wildfires, ongoing efforts have increasingly shifted towards the study and development of reconfigurable systems. The list encompasses field-programmable gate arrays [18], reconfigurable machine tools [19], morphing-wing UAVs [20], and reconfigurable modular space systems [21]. With the escalating global use of UAVs, the concept of reconfigurable UAVs has caught the attention.…”

Our study introduces a new approach, leveraging robotics technology and remote sensing for multifaceted applications in forest and wildfire management. Presented in this paper is PULSAR, an innovative UAV with reconfigurable capabilities, able of operating as a quadcopter, a co-axial quadcopter, and a standalone octocopter. Tailored to diverse operational requirements, PULSAR accommodates multiple payloads, showcasing its adaptability and versatility. This paper meticulously details material selection and design methods, encompassing both initial and detailed design, while the electronics design section seamlessly integrates essential avionic components. The 3D drone layout design, accomplished using SOLIDWORKS, enhances understanding by showcasing all three different configurations of PULSAR’s structure. Serving a dual purpose, this study highlights UAV applications in forest and wildfire management, particularly in detailed forest mapping, edge computing, and cartographic product generation, as well as detection and tracking of elements, illustrating how a UAV can be a valuable tool. Following the analysis of applications, this paper presents the selection and integration of payloads onto the UAV. Simultaneously, each of the three distinct UAV configurations is matched with a specific forest application, ensuring optimal performance and efficiency. Lastly, computational validation of the UAV’s main components’ structural integrity is achieved through finite element analysis (FEA), affirming the absence of issues regarding stress and displacement. In conclusion, this research underscores the efficacy of PULSAR, marking a significant leap forward in applying robotics technology for wildfire science.

“…Parametric cost estimating depends on historical data and regression analysis to create Cost Estimating Relationships [10] (CERs). In recent decades, parametric cost estimation models widely used mainly include Unmanned Space Vehicle Cost Model [11] (USCM), Small Satellite Cost Model [12] (SSCM), NASA Instrument Cost Model [13] (NICM), Mission Operations Cost Estimating Tool [14] (MOCET), NASA Air Force Cost Model [15] (NAFCOM), Spacecraft/Vehicle Level Cost Model [16] (SVLCM), and Project Cost Estimating Capability (PCEC) [17], etc. Specifically, SSCM is developed by The Aerospace Corporation, which estimates the development and manufacturing costs of small satellites.…”
