Increased product complexity and the focus on zero defects, especially when manufacturing complex engineered products, means new tools are required for helping workers conduct challenging assembly tasks. Augmented reality (AR) has shown considerable promise in delivering work instructions over traditional methods. Many proof-of-concept systems have demonstrated the feasibility of AR but little work has been devoted to understanding how users perceive different AR work instruction interface elements. This paper presents a between-subjects study looking at how interface elements for object depth placement in a scene impact a user’s ability to quickly and accurately assemble a mock aircraft wing in ...


Time-Optimal Path Planning For Automated Grain Carts, Mengzhe Zhang, Sourabh Bhattacharya Jan 2015

Time-Optimal Path Planning For Automated Grain Carts, Mengzhe Zhang, Sourabh Bhattacharya

Mechanical Engineering Conference Presentations, Papers, and Proceedings

In this paper, we address a motion planning problem for an autonomous agricultural vehicle modeled as tractor-trailer system. We first present a numerical approach and a primitive-based approach for computing the time-optimal path based on given static initial and goal configurations. In the former approach, we define a value function for the entire state space. The value function is consistent with the time to reach goal configuration, and it is finally used to compute the optimal trajectory. In the latter approach, based on the regular and singular primitives, we present an algorithm to construct such primitives and derive the final ...

As markets demand engineered products faster, waiting on the cyclical design processes of the past is not an option. Instead, industry is turning to concurrent design and interdisciplinary teams. When these teams collaborate, engineering CAD tools play a vital role in conceptualizing and validating designs. These tools require significant user investment to master, due to challenging interfaces and an overabundance of features. These challenges often prohibit team members from using these tools for exploring alternatives. This paper presents a method allowing users to interact with a design using intuitive gestures and head tracking, all while keeping the model in a ...

Despite some progress in increasing the numbers of women and minorities in engineering over the past 30 years, their full participation in the discipline has yet to be achieved, particularly in engineering academia. One cause is the "leaky pipeline"; even after women and minorities choose to major in engineering, they drop out at rates higher than their counterparts along all career stages (undergraduate school, graduate school, tenure-track, etc.). Their small numbers creates isolation that has the unfortunate risks of struggle, less professional success, less sense of personal belonging, and less retention. Our hypothesis is that building a community that provides ...
