The Impact

The Contact and Channel Approach (C&C-A) has been developed to support the decomposition and design of technical systems. It is based on the principle that function and form emerge together during design, and therefore should be considered together in a design representation. This paper discusses the theory underlying the C&C-A, and describes its formalization and implementation in a software tool. The approach is applied to model the system architecture of a humanoid robot arm considering the impact of a proposed design change. This illustrates some of the main benefits of the Contact and Channel Approach: helping designers visualize, understand and communicate the complex dependencies between function and form in a system architecture.

Modelling Approach

To support the development and analysis of engineering designs at the embodiment stage, designers work iteratively with representations of those designs as they consider the function and form of their constituent parts. Detailed descriptions of “what a machine does” usually include flows of forces and active principles within the technical system, and their localization within parts and across the interfaces between them. This means that a representation should assist a designer in considering form and function at the same time and at different levels of abstraction. This paper describes a design modelling approach that enables designers to break down a system architecture into its subsystems and parts, while assigning functions and flows to parts and the interfaces between them. In turn, this may reveal further requirements to fulfil functions in order to complete the design. The approach is implemented in a software tool which provides a uniform, computable language allowing the user to describe functions and flows as they are iteratively discovered, created and embodied. A database of parts allows the user to search for existing design solutions. The approach is illustrated through an example: modelling the complex mechanisms within a humanoid robot.

In this paper, problems for an anthropomorphic robot arm are approached for an application in a humanoid robot with the specific features of cost oriented design and user-friendly operation. One DOF solution is proposed by using a suitable combination of gearing systems, clutches, and linkages. Models and dynamic simulations are used both for designing the system and checking the operation feasibility.

The Impact

The main purpose of this article was to determine the impact on the equilibrium of the local transport system from privileging EVs by permitting them to use bus lanes. The study used two sets of data: information on infrastructure and traffic management; and information on the recorded road network loads and traffic volumes generated by a given shopping centre—the E. Leclerc shopping centre (an important traffic generator within the city of Łódź, Poland). These sets were then used to develop a microsimulation traffic model for the shopping centre and the associated effects on the localised transport system. The model was constructed by means of the PTV Vissim software tool. An initial simulation was conducted that formed a basis for subsequent scenarios (in total, 17 simulations were performed). On the basis of the conducted analyses, it was established that—for the researched part of the transport system—privileging the still rather uncommon battery electric vehicles (BEVs) engendered a marginal deterioration of traffic conditions. At the same time, allowing BEVs to use bus lanes within the chosen research area had no negative impact on bus journey times.

The Impact

This paper describes the process of developing a software tool for digital artistic exploration of 3D human figures. Previously available software for modeling mesh-based 3D human figures restricts user output based on normative assumptions about the form that a body might take, particularly in terms of gender, race, and disability status, which are reinforced by ubiquitous use of range-limited sliders mapped to singular high-level design parameters. CreatorCustom, the software prototype created during this research, is designed to foreground an exploratory approach to modeling 3D human bodies, treating the digital body as a sculptural landscape rather than a presupposed form for rote technical representation. Building on prior research into serendipity in Human-Computer Interaction and 3D modeling systems for users at various levels of proficiency, among other areas, this research comprises two qualitative studies and investigation of the impact on the first author's artistic practice. Study 1 uses interviews and practice sessions to explore the practices of six queer artists working with the body and the language, materials, and actions they use in their practice; these then informed the design of the software tool. Study 2 investigates the usability, creativity support, and bodily implications of the software when used by thirteen artists in a workshop. These studies reveal the importance of exploration and unexpectedness in artistic practice, and a desire for experimental digital approaches to the human form.

The Impact

In the context of industrial production, a worker that wants to program a robot using the hand-guidance technique needs that the robot is available to be programmed and not in operation. This means that production with that robot is stopped during that time. A way around this constraint is to perform the same manual guidance steps on a holographic representation of the digital twin of the robot, using augmented reality technologies. However, this presents the limitation of a lack of tangibility of the visual holograms that the user tries to grab. We present an interface in which some of the tangibility is provided through ultrasound-based mid-air haptics actuation. We report a user study that evaluates the impact that the presence of such haptic feedback may have on a pick-and-place task of the wrist of a holographic robot arm which we found to be beneficial.

Financial Losses

Subject. The article addresses scientific and technical risk and financial losses of the customer in the process of research and development works on the creation of complex technical systems. Objectives. The study aims at constructing and analyzing the dependence of scientific and technical risk and financial losses of the customer on the planned volume of development works and the financial resources invested in them. Methods. We apply methods of probability theory and mathematical statistics, system and regression analysis, risk assessment and management. The paper rests on data on completed development projects for complex technical systems creation. Results. We formulated methodological provisions for assessing scientific and technical risk, arising in the process of development works on complex technical systems. The paper presents an algorithm for calculating the expected financial losses from works implementation. The problem of minimizing financial losses associated with scientific and technical risk is formulated and formalized. The feasibility of proposed provisions and recommendations is confirmed by a practical example. Conclusions. To assess risks, it is important to consider the impact of the degree of difference between the main characteristics of developed product and its prototype on the required amount of works at development stage. This enables to build regression dependencies of the volume of works at the development stage on a specified factor, which are later used to assess the scientific and technical risk and associated financial losses.
