In this paper, we describe some initial results of a project aiming at development of a programmablecompliance, inherently safe robot arm for applications in anthropic environmnets. In order to obtain safety in spite of worst-case situations (such as unexpected delays in teleoperation, or even controller failure), we will consider achieving compliance by mechanical rather than by control design...

This paper discusses our preliminary analysis of how designer and non-designer participants discussed and engaged in design activity. For this research, we employed two design study experiments that included a total of forty-eight participants. In our preliminary findings we found differences between designers and nondesigners in how a design activity is analyzed. The more significant prelimina...

Electro-hydrostatic actuators (EHAs) are expanding their application fields due to combined advantages of electric and hydraulic actuation. However, the control performance, weight, efficiency turn out be more challenging requirements when EHA power level increases over 30 kW. Therefore, a preliminary design dedicated trading off system-level performance based on multi-domain coupling analysis ...

Abstract Mindset has been identified as an essential aspect of design and innovation, impacting both behaviours performance. However, the concept mindset is elusive. Often used indistinguishably from behaviour, diminishing complexity mechanisms cognitive processes underlying behaviour. As initial step in researching these mechanisms, we operationalise present inventory (D-Mindset0) to measure i...

An Abaqus/Standard FEA based study was carried out to develop a structural format for a wing sail used on a sailing boat, V-39 Albatross. As well as providing a novel structural solution to meet a challenging set of requirements, the study has given the necessary mass properties and stiffness data required to further progress the preliminary design phase of the overall boat. The brief for the b...

B-Spline and NURBS surfaces are most often considered to model objects. The object shape is designed by manipulating several control points, which is often very complex and tedious. The declarative approach of surface modelling is a fast and easy way to obtain sketches of parametric surfaces. The designer provides a description of the shape he/she wants to obtain. The semantic extracted from th...
