Application Of An Intuitive, Glove-Type Remote Control With Haptic Feedback To Quadcopters, Luke M. Stacey Apr 2019

Application Of An Intuitive, Glove-Type Remote Control With Haptic Feedback To Quadcopters, Luke M. Stacey

Senior Honors Theses

Although remote controllers for drones, based upon a classic two-joystick architecture, are unwieldy, they still see widespread use. As a replacement, we propose a remote control with a glove-based architecture that utilizes haptic feedback from the quadcopter. The proposed controller should be far more intuitive, making drone flight easier and more intuitive. Additionally, since the pilot will have one hand free, he or she can use maps, electronics, and other aids much more straightforwardly than with a two-handed controller. While our technology is designed for drones, it also could see further usage in a wide variety of civilian and military ...

Driver Performance Due To Unmanned Aerial System Applications In The Vicinity Of Surface Transportation, Alyssa M. Ryan

Transportation Engineering Masters Projects

Unmanned aerial systems (UAS), or drones, have become increasingly utilized for a myriad of applications in the vicinity of the roadway and can offer a low-cost alternative to many labor-intensive data collection techniques, including infrastructure inspection, roadway marking data collection, and more. To collect much of this data with a desired degree of accuracy, UAS must be flown near moving vehicles, pedestrians, and/or bicyclists. However, UAS, and their pilot/crew, have the potential to be a distraction to drivers. A study by Hurwitz et al. suggests that UAS operations are more distracting to drivers as the UAS traverses closer ...

Comparison Of Fixed-Wing Unmanned Aircraft Systems (Uas) For Agriculture Monitoring, Joseph Cerreta, Kristine M. Kiernan

International Journal of Aviation, Aeronautics, and Aerospace

Florida citrus growers need inexpensive methods to observe citrus plants to detect disease and stress consistently. Health vegetation indices, such as the Normalized Difference Vegetation Index (NDVI) collected from Unmanned Aircraft Systems (UAS), can be used to identify variation in plant health. Simple-to-operate UAS may enable growers to determine within-field variation more frequently than with inspections from scouts, providing more frequent knowledge about the crop condition. This research compared two low-cost fixed-wing UAS, a $5,000 Parrot Disco Pro Ag and a $16,690 senseFly eBee, each equipped with a Parrot Sequoia multispectral camera, to determine if there were differences ...

The Effect Of Communication And Vehicle Properties On The Search Performance Of A Swarm Of Unmanned Aerial Vehicles, Jenna E. Newcomb, Andrew Ning

Faculty Publications

An unmanned aerial vehicle (UAV) swarm allows for a more time-efficient method of searching a specified area than a single UAV or piloted plane. There are a variety of factors that affect how well an area is surveyed. We specifically analyzed the effect both vehicle properties and communication had on the swarm search performance. We used non-dimensionalization to examine the effect vehicle properties had on search performance so the results can be applied to any domain size with any number and type of vehicle. We found that even if vehicles could only sense 10% of the grid area at any ...
