PVCROV : an experimental platform for multi-robot control systems

As the field of multi-robot control systems grows, the demand for flexible, robust and precise multi-robot testbeds increases. Up to this point, the testbeds that do exist for testing multi-robot controllers are often expensive, hard to deploy, and typically constrained to a single plane of motion. These constraints limit the capacity to conduct research which is why team Autonomously Controlled Electromechanical Systems (ACES) has created the PVCROV system. PVCROV is a low cost, underwater platform for testing multi-robot control systems. By utilizing an underwater environment, ACES created a testbed that is not constrained to a single plane of motion. Additionally, the advantage of an underwater testbed is the ability to simulate weightlessness, as if in a space environment. Both of these features make this testbed extremely valuable to multi-robot research as they open the door for conducting experiments that previously could not be performed. ACES final product consisted of four PVCROV\u27s tethered to a surface buoy with wireless command and control via an \u27onshore\u27 control computer. Each system was designed, simulated, manufactured and tested based on requirements developed from a customer needs survey performed with the targeted research team. Although complete functionality was not achieved, a new team of students has started a new iteration of the development process which will bring the system up to full functionality. With graduate student experimenters already involved, ACES has created a testbed that will provide great value to the robotics research program at SCU

Educational Attainment, Sex, and Socioeconomic Status in the Context of Aging

Education is a known protective factor for normal aging. People who are able to pursue higher education are less likely to experience abnormal cognitive decline as they age (Lövdén et al., 2020). Socioeconomic status (SES) may also have an impact on sustained brain function. Greater wealth leads to greater opportunities for cognitive, social, and physical growth and maintenance (Steptoe and Zaninotto, 2020). Sex is another factor impacting SES and education. Females tend to have lower levels of education due to many sociocultural factors, including geographical location as well as family expectations (Hendrick et al., 2016). Therefore, we hypothesized that higher SES will lead to higher educational attainment, being male will lead to higher educational attainment, females with low SES will have the lowest educational attainment, and males with high SES will have the highest educational attainment. This study’s data came from mySidewalk, which collects and organizes health data for the community. We obtained median household income and male/female educational attainment variables from the database. Results revealed that higher SES will lead to higher educational attainment and being male will lead to higher educational attainment. The other hypotheses were not supported; further research needs to be done to better understand sex differences in relation to education. Education is correlated with income, indicating that SES may be a factor for healthy aging as well. These results can help us target specific populations in order to give them the best resources for healthy aging
