For decades, women in the field of sports media have battled for equality with their male counterparts. In 1972, Title IX was passed, stating that “no person in the United States shall, on the basis of sex, be excluded from participation in, be denied the benefits of, or be subject to discrimination under any educational program or activity receiving Federal financial assistance.” In 1978, the iconic court case, Melissa Ludtke and Time Inc., v. Bowie Kuhn, Commissioner of Baseball, confirmed that the Fourteenth Amendment guarantees that women should be given the same rights as men, specifically in regards to locker room access. Today, legally women and men in the field of sports media have the same rights. But many people would argue that is not the case. In the five decades succeeding these milestones, women have continued their fight for a more level playing field. Women in sports media are largely stereotyped, they are often judged based on their looks not their knowledge, they are underrepresented in a field that is male dominated. It could be assumed most women working in sports media have at least one instance where they have been judged on the basis of sex. And in 2021, sexual harassment allegations are still being made in the industry.. How will the events of this decade shape the future for women in this field? What strides are left to be made and how will they be achieved?

Towards enabling a UAV to autonomously sense and avoid moving obstacles, this thesis makes the following contributions. Initially, an image-based reactive motion planner is developed for a quadrotor to avoid a fast approaching obstacle. Furthermore, A Dubin’s curve based geometry method is developed as a global path planner for a fixed-wing UAV to avoid collisions with aircraft. The image-based method is unable to produce an optimal path and the geometry method uses a simplified UAV model. To compensate
these two disadvantages, a series of algorithms built upon the Closed-Loop Rapid Exploratory Random Tree are developed as global path planners to generate collision avoidance paths in real time. The algorithms are validated in Software-In-the-Loop (SITL) and Hardware-In-the-Loop (HIL) simulations using a fixed-wing UAV model and in real flight experiments using quadrotors. It is observed that the algorithm enables a UAV to avoid moving obstacles approaching to it with different directions and speeds.
