As robots become more prevalent, the need is growing for efficient yet stable control systems for applications with humans in the loop. As such, it is a challenge for scientists and engineers to develop robust and agile systems that are capable of detecting instability in teleoperated systems. Despite how much research has been done to characterize the spatiotemporal parameters of human arm motions for reaching and gasping, not much has been done to characterize the behavior of human arm motion in response to control errors in a system. The scope of this investigation is to investigate human corrective actions in response to error in an anthropomorphic teleoperated robot limb. Characterizing human corrective actions contributes to the development of control strategies that are capable of mitigating potential instabilities inherent in human-machine control interfaces. Characterization of human corrective actions requires the simulation of a teleoperated anthropomorphic armature and the comparison of a human subject's arm kinematics, in response to error, against the human arm kinematics without error. This was achieved using OpenGL software to simulate a teleoperated robot arm and an NDI motion tracking system to acquire the subject's arm position and orientation. Error was intermittently and programmatically introduced to the virtual robot's joints as the subject attempted to reach for several targets located around the arm. The comparison of error free human arm kinematics to error prone human arm kinematics revealed an addition of a bell shaped velocity peak into the human subject's tangential velocity profile. The size, extent, and location of the additional velocity peak depended on target location and join angle error. Some joint angle and target location combinations do not produce an additional peak but simply maintain the end effector velocity at a low value until the target is reached. Additional joint angle error parameters and degrees of freedom are needed to continue this investigation.

Long distance travel around the globe can potentially be revolutionized with the use of an intercontinental rocket that uses low earth orbit as its medium. This transport system can increase growth in many new businesses like tourism travel between the continents. This research evaluates the technical and non-technical possibilities

Long distance travel around the globe can potentially be revolutionized with the use of an intercontinental rocket that uses low earth orbit as its medium. This transport system can increase growth in many new businesses like tourism travel between the continents. This research evaluates the technical and non-technical possibilities of using a double-stage reusable rocket, where the second stage is also a reusable, rocket-powered passenger vehicle using a low earth orbit space journey with a stabilized re-entry method that ensures passenger comfortability. A potential network of spaceports spanning the globe is postulated within a range of 4,000 km to 8,000 km(2,160 nm to 4,320 nm) of each other, and each located within an hour by any other means of ground transport to population hubs greater than four million. This will help further connect the world as the journey from one major city to another would take at most an hour, and no point on the habited continents would be more than 4,000 km(2,160 nm) from a spaceport. It is assumed that the costs of an international first class flight ticket are in the thousands of dollars range showing how there is a potential market for this type of travel network. The reasoning and analysis, through a literature review, for an intercontinental rocket vehicle is presented along with the various aspects of the possibility of this kind of travel network coming to fruition in the near future.

The NCAA is changing the current rules and regulations around a student-athlete’s name, image, and likeness. Previously, student-athletes were not allowed to participate in business activities or noninstitutional promotional activities. With the new rule changes, student-athletes will be able to engage in business activities related to their own name, image, and likeness. The goal of the team was to help “prepare athletes to understand and properly navigate the evolving restrictions and guidelines around athlete name, image, and likeness”. In order to accomplish this, the team had to understand the problems student-athletes face with these changing rules and regulations. The team conducted basic market research to identify the problem. The problem discovered was the lack of communication between student-athletes and businesses. In order to verify this problem, the team conducted several interviews with Arizona State University Athletic Department personnel. From the interviews, the team identified that the user is the student-athletes and the buyer is the brands and businesses. Once the problem was verified and the user and buyer were identified, a solution that would best fit the customers was formulated. The solution is a platform that assists student-athletes navigate the changing rules of the NCAA by providing access to a marketplace optimized to working with student-athletes and offering an ease of maintaining relationships between student-athletes and businesses. The solution was validated through meetings with interested brands. The team used the business model and market potential to pitch the business idea to the brands. Finally, the team gained traction by initiating company partnerships.

Students from the Founder’s Lab at ASU created Equalitree, a company whose main focus is bringing together fans, student-athletes, coaches, and executive staff. In developing the company, the founders looked at various data points from the NCAA about what is already being done to increase diversity and inclusion. After finding staggering statistics about the state of diversity, the founders began to create ‘Equalitree’. A consulting agency tackling diversity and inclusion. The goal is to increase diversity and inclusion within sports organizations through a series of educational events, social campaigns, and dialogues. In researching the effectiveness of this business model, the founders hosted a week of events. The first event was a dialogue, in which attendees were presented with statistics of diversity within college sports, what is being done on college campuses to bridge gaps and open dialogues, and even held a discussion. For the second event, the founders hosted Keynote Speaker, former NFL player L.J. Shelton, to speak on his experiences within college sports and the NFL. Overall, Equalitree received highly rated reviews and feedback from attendees about the events and the effectiveness.

Titanium has been and continues to be a popular metal across any form of manufacturing and production because of its extremely favorable properties. In important circumstances, it finds itself outclassing many metals by being lighter and less dense than comparably strong metals like steel. Relative to other metals it has a noteworthy corrosion resistance as it is stable when it oxidizes, and due to the inert nature of the metal, it is famously hypoallergenic and as a result used in a great deal of aviation and medical fields, including being used to produce replacement joints, with the notable limitation of the material being its cost of manufacturing. Among the variants of the metal and alloys used, Ti6Al4V alloy is famous for being the most reliable and popular combination for electron beam manufacturing(EBM) as a method of additive manufacturing. <br/>Developed by the Swedish Arcam, AB, EBM is one of the more recent methods of additive manufacturing, and is notable for its lack of waste by combining most of the material into the intended product due to its precision. This method, much like the titanium it is used to print in this case, is limited mostly by time and value of production. <br/>For this thesis, nine different simulations of a dogbone model were generated and analyzed in Ansys APDL using finite element analysis at various temperature and print conditions to create a theoretical model based on experimentally produced values.

This project dives into the journey of our entrepreneurial startup with the Founders Lab Thesis Program. In the global sports business industry, we knew that there was something missing. While conducting market research, there was little data and information about sustainability initiatives that engaged sports fans, especially in college sports. Not to mention, there was no sustainability information provided on any existing platforms that sporting teams use for ticketing and advertising. So, for our startup, we decided to create a website called SustainSports which gives fans the opportunity to inform themselves about sustainability initiatives at sports events (https://sustainsports.webflow.io/). These fans can also earn points and rewards for practicing sustainability activities at home. In short, SustainSports serves as an educational, interactive, and informative website that connects users to sustainability initiatives, community activities, and exciting rewards, while encouraging users to continue such environmentally-friendly practices in their daily lives. In chronological order, this thesis paper will examine the process we took to create SustainSports and demonstrate our efforts that properly allowed us to defend it one academic year later. From meetings with renowned sports enthusiasts and professors to interviews with ASU students and sports fans, we have listened to and taken in diverse perspectives to understand the perceptions of sustainability in the global sports industry. When we realized that there was a significant gap between sports and sustainability - both important elements of American society and culture - we knew a change needed to be made. Hence, SustainSports came to life, offering users a fresh opportunity to be more aware of their sustainability surroundings, while simultaneously enjoying the sports they know and love.
