Barrett, The Honors College Thesis/Creative Project Collection
Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.
Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

To achieve this goal, a model of a swarm performing a collective transport task in a bounded domain featuring convex obstacles was simulated in MATLAB/ Simulink®. The closed-loop dynamic equations of this model were linearized about an equilibrium state with angular acceleration and linear acceleration set to zero. The simulation was run over 30 times to confirm system ability to successfully transport the payload to a goal point without colliding with obstacles and determine ideal operating conditions by testing various orientations of objects in the bounded domain. An additional purely MATLAB simulation was run to identify local minima of the Hessian of the navigation-like potential function. By calculating this Hessian periodically throughout the system’s progress and determining the signs of its eigenvalues, a system could check whether it is trapped in a local minimum, and potentially dislodge itself through implementation of a stochastic term in the robot controllers. The eigenvalues of the Hessian calculated in this research suggested the model local minima were degenerate, indicating an error in the mathematical model for this system, which likely incurred during linearization of this highly nonlinear system.
muscular hydrostat, which allows for nearly infinite degrees of freedom of movement without
the structure of a skeletal system. This study employed Magnetic Resonance Imaging with a
Gadoteridol-based contrast agent to image the octopus arm and view the internal tissues. Muscle
layering was mapped and area was measured using AMIRA image processing and the trends in
these layers at the proximal, middle, and distal portions of the arms were analyzed. A total of 39
arms from 6 specimens were scanned to give 112 total imaged sections (38 proximal, 37 middle,
37 distal), from which to ascertain and study the possible differences in musculature. The
images revealed significant increases in the internal longitudinal muscle layer percentages
between the proximal and middle, proximal and distal, and middle and distal sections of the
arms. These structural differences are hypothesized to be used for rapid retraction of the distal
segment when encountering predators or noxious stimuli. In contrast, a significant decrease in
the transverse muscle layer was found when comparing the same sections. These structural
differences are hypothesized to be a result of bending behaviors during retraction. Additionally,
the internal longitudinal layer was separately studied orally, toward the sucker, and aborally,
away from the sucker. The significant differences in oral and aboral internal longitudinal
musculature in proximal, middle, and distal sections is hypothesized to support the pseudo-joint
functionality displayed in octopus fetching behaviors. The results indicate that individual
octopus arm morphology is more unique than previously thought and supports that internal
structural differences exist to support behavioral functionality.
To achieve this goal, a model of swarm robots transportation should be designed, which is cruise control for this scenario. Secondly, based on free body diagram, force equilibrium equation can be deduced. Then, the function of plant can be deduced based on cruise control and force equilibrium equations. Thirdly, list potential controllers, which may implement desired controls of swarm robots, and test their performance. Modify value of gains and do simulations of these controller. After analyzing results of simulation, the best controller can be selected.
In the last section, there is conclusion of entire thesis project and pointing out future work. The section of future work will mention potential difficulties of building entire control system, which allow swarm robots transport over inclines in real environment.
Baked by Barrett facilitates the collection, review, and sale of home-baked goods through various means weekly. This will include, while not limited to, hosting tabling and social events throughout the academic year. This user-led platform will share the proceeds with bakers, and local charities of choice while maintaining a percentage internally to ensure efficient operations. Because businesses for profit are a conflict of interest for ASU, the organization will work to promote students and charity along with the learning for business and entrepreneurial ventures. Instead of generating profits, Baked by Barrett will focus on sustaining itself while the rest of the revenue will go to charity. This will help the organization avoid conflicts of interest with ASU allowing it to use campus space to sell. Marketing will, initially, be based on word-of-mouth, with supporting tools including a dynamic website, flyers, and partnerships around local newsletters. Rotations of charities and menu items will be used to incentivize students and passersby to buy from Baked by Barrett. In order to promote the organization, there will be a website, flyers, and even contact information through the Barrett digest to market the platform in the weekly newsletter.
This thesis paper outlines the Ctrl+P print store business, an honors thesis project conducted through the Founder’s Lab program at Arizona State University. The project is an online store for 3D printed items, operated by a team of four students with backgrounds in engineering and finance. Three team members have experience in computer-aided design (CAD) and can design products to print and sell, while the fourth member is responsible for the financial side of the business. The project began with a broader scope but later focused on the niche community of pool. In the spring semester, the team conducted customer discovery with over 600 ASU students; and in the fall semester, reached out to several pool halls to facilitate feedback on designs of custom pool racks. The team currently has a pending business deal with Mill’s Modern Social, a pool hall and bar in Tempe. The team's goal was to be revenue-earning by the end of the project, and they have already made a profit as a business.
