A vector field navigation system was shown to avoid dynamic obstacles and reach a goal with a prespecified position and heading using a simulated Ackerman vehicle. The navigation system was divided into two distinct vector fields, an environmental field which was created for goal oriented navigation and obstacle field which was designed for obstacle avoidance. Discussed in this paper were the methods of obstacle avoidance and combining the two fields of the navigation system. The obstacle avoidance method created a rotational vector field centred on a single obstacle. Algorithms were created to select the obstacle that would be the centre of the field and the direction of rotation of the field. A parameter based method was used to combine the obstacle field and the environmental field. A simulation workspace was created to show the navigation behaviours created by combining these methods and a sample of these results were presented in this paper.
Digital Engineering, like any initiative, should have a clear purpose and direction. For organisations that sit as Acquirers/Clients the Digital Transformation may not seem immediately valuable. However, for this group Digital Engineering can provide opportunities to tightly engage with their supplier network, understand trade-offs through design and upgraded lifecycles and enhanced supplier outcomes.This paper discusses the benefits and challenges of adopting Digital Engineering in the Concept Phase, where most of the project costs are committed. It highlights that the greatest return on investment for Digital Engineering is during Concept Phase as the flow of authoritative information permeates the remainder of the lifecycle. This presents the case for acquisition agencies to both drive the application of Digital Engineering within their industry and lead by example, through Digital Engineering adoption.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
