A Spatial Grammar Method for the Computational Design Synthesis of Virtual Soft Locomotion Robots
Merel van Diepen and Kristina Shea
Soft locomotion robots are intrinsically compliant and have a large number of degrees of freedom. However, the hand-design of soft robots is often a lengthy trail-and-error process. This paper presents the computational design of virtual, soft locomotion robots using an approach that integrates simulation feedback. The Computational Design Synthesis (CDS) approach consists of three stages: (1) generation, (2) evaluation through simulation, and (3) optimization. Read more...
Managing Sociotechnical Complexity in Engineering Design Projects
Mohammad Hassannezhad, Marco Cantamessa, Francesca Montagna and P. John Clarkson
A key challenge in lengthy and labor-intensive design projects is leveraging knowledge and expertise. Tools are needed that reflect the social and technical characteristics of design processes. Such integrated modelling is particularly critical in the early stages of design where information is imprecise and decisions have significant consequence. This paper contributes to the development of Actor-Based Signposting (ABS) - a dynamic method that combines the Activity-based and Agent-based concepts of process modelling. This approach enables individuals to be adaptive in satisfying the local objectives of their own jobs while complying with the global objectives of the rest of the team/entire system. Read more...
Design and Optimization of Graded Cellular Structures with Triply Periodic Level Surface-Based Topological Shapes
Dawei Li, Ning Dai, Yunlong Tang, Guoying Dong, and Yaoyao Fiona Zhao
Periodic cellular structures with excellent mechanical properties widely exist in nature. Examples include shark skin, bone structure, etc. This research introduces a generative design and optimization method for triply periodic level surface (TPLS)-based functionally graded cellular structures. In the proposed method, the density distribution is controlled so that the TPLS-based cellular structures can achieve better structural or thermal performances without increasing the weight of the structure.
