Adoption of vehicular ad hoc networking protocols by networked robots

This paper focuses on the utilization of wireless networking in the robotics domain. Many researchers have already equipped their robots with wireless communication capabilities, stimulated by the observation that multi-robot systems tend to have several advantages over their single-robot counterparts. Typically, this integration of wireless communication is tackled in a quite pragmatic manner, only a few authors presented novel Robotic Ad Hoc Network (RANET) protocols that were designed specifically with robotic use cases in mind. This is in sharp contrast with the domain of vehicular ad hoc networks (VANET). This observation is the starting point of this paper. If the results of previous efforts focusing on VANET protocols could be reused in the RANET domain, this could lead to rapid progress in the field of networked robots. To investigate this possibility, this paper provides a thorough overview of the related work in the domain of robotic and vehicular ad hoc networks. Based on this information, an exhaustive list of requirements is defined for both types. It is concluded that the most significant difference lies in the fact that VANET protocols are oriented towards low throughput messaging, while RANET protocols have to support high throughput media streaming as well. Although not always with equal importance, all other defined requirements are valid for both protocols. This leads to the conclusion that cross-fertilization between them is an appealing approach for future RANET research. To support such developments, this paper concludes with the definition of an appropriate working plan

Redesign of Tactical Backpack

We worked to assess the current Marine Corps Standard Issue Tactical Pack System in an effort to make it more desirable for use in extreme situations. Our project\u27s final objective addressed the supplementary dry pack system designed by Cascade Designs Inc. - the MACS Sack. Our efforts yielded a final proposal which incorporated lightweight and durable additions to the existing MACS Sack design. These additions improved the functional capacity of the MACS Sack for Marine Corps Dive Operations. By assembling a comprehensive literature background, we found that our results provided greater improvements over the exiting MACS Sack systems

Identification and evaluation of innovation opportunities emerging from technology and business trends

Master's thesis in Offshore Technology : Industrial Asset ManagementNew technology emerges faster than ever before, and the development is increasing exponentially. The speed of development is too rapid for businesses to investigate and identify potential value from them. There is a need for a culture of innovation and technology adoption and must be treated as the backbone of the company’s value chain. This master will explore a systematic approach to investigate and evaluate innovation opportunities emerging from technology and business trends. The goal of the project is to prove that a systematic method may assist the industry in identifying and evaluating opportunities to achieve competitive advantages. The method consisted of three main parts; 1. Selection and screening of industry 2. Screening of technology trends and business trends with potential for disrupting the industry 3. Identification and evaluation of ideas. The selected industry was Norwegian salmon farming and segment was salmon sea farming production. In total, 14 ideas were elaborated in this thesis. 9 ideas were rejected by the first screening. 5 ideas reached the second screening where 3 ideas were rejected at this point. 2 ideas cleared the second screening had potential to be a business opportunity and was evaluated in a business model canvas. The research prove that it is possible to systematically identify and screen innovation opportunity emerging from technology and business trends today. Time and access to information is identified as the two main enablers to increasing quality of the ideas, in addition to selecting an industry with innovation potential

Marine Robot Sample Retrieving System

The exploration of our underwater ecosystems is critical. The aquatic ecosystem has a significant effect on human life, yet our understanding of the oceanic environment is severely lacking. Santa Clara University’s Robotic Systems Lab contributes to subsea exploration through its investment in remotely operated vehicle (ROV) technology. This project was done with the guidance of not only professors in the Robotics Systems Lab, but also stakeholders from the US Geological Survey scientists and researchers from the Monterey Bay Aquarium Research Institute (MBARI). Our team goal was to further advance SCU’s efforts by creating a sediment sample collection system consisting of a manipulator arm and sample storage container compatible with an existing SCU ROV. Our project has the potential to give researchers better access to submerged ecosystems and assists their efforts to understand and protect subsea environments in the future. We designed, built, and tested a prototype of a multiple degree-offreedom arm and storage system for the existing Nautilus ROV, for safely manipulating and storing submerged sedimentary artifacts at 300 feet deep with a maximum dive time of 45 minutes. At the end of this project, we were able to see robust three degree of freedom movement of the arm within its anticipated workspace. We achieved a basic level of motion control of the arm which was successfully tested and evaluated within a testing tank. However, there is still need for additional testing and increased functionality of the mechanical and controls systems. The storage system for samples design needs a thrust bearing to better rotate and there is still much work to make the controls of the arm user friendly such as end effector control for depositing a sample into the storage system instead of doing all the movements manually

The use of technology to improve swimming performance: skill focus

When working with elite swimmers, it is necessary to determine areas in which small changes can result in improved performances during the pinnacle events each year as a culmination of improvements within the daily training environment. The swimming skills of starts and turns comprise approximately 30% of the total race time in events with distances up to 100m (Thayer and Hay, 1984) indicating the importance of skills to overall race performances. Data from the 2011 World Championships is presented to highlight the percentage of race time spent in the start and turn phases for all events. [Continues.

Localization, Mapping and SLAM in Marine and Underwater Environments

The use of robots in marine and underwater applications is growing rapidly. These applications share the common requirement of modeling the environment and estimating the robots’ pose. Although there are several mapping, SLAM, target detection and localization methods, marine and underwater environments have several challenging characteristics, such as poor visibility, water currents, communication issues, sonar inaccuracies or unstructured environments, that have to be considered. The purpose of this Special Issue is to present the current research trends in the topics of underwater localization, mapping, SLAM, and target detection and localization. To this end, we have collected seven articles from leading researchers in the field, and present the different approaches and methods currently being investigated to improve the performance of underwater robots
