Kwad - Ksu All Weather Autonomous Drone, Nick Farinacci, Sebastian Gomez, Stewart Baker, Ed Sheridan

Symposium of Student Scholars

"KWAD" or "KSU all-Weather Autonomous Drone" project was sponsored by Ultool, LLC to the KSU Research and Service Foundation to create a lightweight drone capable of capturing HD video during all-weather operations. The conditions of all-weather operation include rainfall of one inch per hour and wind speeds of up to twenty miles per hour. In addition, a global minimum structural safety factor of two is required to ensure the system's integrity in extreme weather conditions. Potential mission profiles include autonomous aerial delivery, topological mapping in high moisture areas, security surveillance, search and rescue operations, emergency transportation of medical supplies, and …

Utilisation Des Ponts Élévateurs De Véhicules Hors Terre À Deux Colonnes : Identification De Déterminants Techniques De Stabilité Et Des Déterminants Du Travail Des Techniciens Automobiles, Damien Burlet-Vienney, Sylvie Beaugrand, Bertrand Galy, Maud Gonella, François Gauthier, Élise Ledoux, Isabelle Berger, Isvieysys Armas Marrero, Kariane Cusson Bertrand

Rapports de recherche scientifique

Cette recherche porte spécifiquement sur l’utilisation des ponts élévateurs de véhicules (PEV) hors terre à deux colonnes (HT2C). Les PEV HT2C sont utilisés par les techniciens automobiles lors de l’entretien et de la réparation des véhicules et les amènent à travailler sous ou à proximité d’une charge surélevée de plusieurs tonnes. La mort d’un jeune technicien en 2014 est à l’origine d’une concertation du secteur de la réparation automobile et de ces travaux de recherche. La chute d’un véhicule d’un PEV HT2C est le risque ciblé par cette étude.

De nombreux facteurs sont susceptibles de contribuer à la chute d’un …

Critères De Stabilité Des Échelles Et Des Escabeaux, Bertrand Galy

Rapports de recherche scientifique

Les chutes de hauteur sont encore aujourd’hui une des principales causes d’accident au Québec, et la deuxième cause en termes de coûts sur la période 2010 – 2012, avec une moyenne de 397 millions de dollars par année. Selon la CNESST, les statistiques de lésions impliquant les échelles, que ce soit en construction ou en établissement, montrent une augmentation au fil des ans (période de 2007 à 2012) et sur la période 2009 à 2013, 20 % des lésions dues à une chute de hauteur ont été causées par une chute à partir d’une échelle.

Un des principaux critères affectant …

Kinematic Analysis Of Forehand Drop Shot And Long Shot Services In Table Tennis, Ibrahim Norzuria

Student Works (2020-2029)

Table tennis is one of the most widely played sports in the world. A frequent hand movement is compulsory to execute stroke than other limbs, especially the projection of racket and ball speeds,which can help to improve players’ performance. Until now, research on table tennis serving is limited. Service was assumed important in table tennis because the effective serve may allow the serving player to have advantage and control over the game. The 3D dynamic analysis is the appropriate method to analyze a sport activity such as table tennis. Therefore, the aim of research was to determine the kinematic involved …

Human Powered Vehicle Internal Systems Design, Zachary Broadbent, Jordan Boos, Patrick Gaertner, Caleb Miner

Williams Honors College, Honors Research Projects

The objective of this design project is to redesign the seat and steering system for the Human Powered Vehicle Team. The goal of the seat design is too improve ergonomics by making it more comfortable and adjustable. In making the seat adjustable, it will be easier for drivers to achieve an optimal efficiency when pedaling. The aim for steering will be to improve the ergonomics as well as performance by analyzing steering systems in the past and evaluating how each design was successful and for what reason. Another main goal of the steering system will be improving the stability and …

Chocolate Bar Wrapping Machine, Austin M. Hoff, Daniel R. Trepke, Caleb B. Krichbuam

Williams Honors College, Honors Research Projects

Gilbert Chocolates has proposed to manufacture a machine to wrap chocolate bars. This machine is intended to replace two people wrapping the chocolate bars by hand, which is a time consuming method. This is especially apparent between October and January when the workers are working long hours in preparation for the Christmas rush of customers. Currently wrapping a bar takes about a minute and Gilbert Chocolates wants this time reduced down to 20-30 seconds. The budget for this project is set at $1000, and is being funded by the company. This machine needs to fit in a cubic foot of …

Effect Of Local Magnetic Field Disturbances On Inertial Measurement Units Accuracy, Xavier Robert-Lachaine, Hakim Mecheri, Christian Larue, André Plamondon

Études primaires

Inertial measurement units (IMUs), a practical motion analysis technology for field acquisition, have magnetometers to improve segment orientation estimation. However, sensitivity to magnetic disturbances can affect their accuracy. The objective of this study was to determine the joint angles accuracy of IMUs under different timing of magnetic disturbances of various durations and to evaluate a few correction methods. Kinematics from 12 individuals were obtained simultaneously with an Xsens system where an Optotrak cluster acting as the reference system was affixed to each IMU. A handling task was executed under normal laboratory conditions and imposed magnetic disturbances. Joint angle RMSE was …

Australian Tractor Test Report No. 41 : The Massey-Ferguson 135, G H. Vasey, F. T. Baillie

Journal of the Department of Agriculture, Western Australia, Series 4

THE Massey-Ferguson MF-135 is a general purpose tractor of 31 drawbar horsepower. It has 14.9 x 24 pneumatic tyres, and a three-speed gear box with a ratio change which, in the standard model, gives six forward and two reverse gears.

The model tested was also fitted with the optional "Multipower" facility, which gives an "on-the-go" shift to a higher speed for each gear, thus providing 12 forward and four reverse gears.

Tractor Testing In Australia, G H. Vasey, W. F. Baillie

Journal of the Department of Agriculture, Western Australia, Series 4

AUSTRALIA is one of several countries that have set up "official" tractor testing schemes.

These schemes mean testing stations that, while providing a testing service for both the manufacturing industry and the consumer, in effect mainly the farming industries, are independent of either.

Tractor Testing In Australia. Part 2, G H. Vasey, W. F. Baillie

Journal of the Department of Agriculture, Western Australia, Series 4

AUSTRALIAN test procedures, though differing: in some details, and in some ways going further and telling more about the tractor, conform in essentials to overseas standards.

The tests are in four main parts—

(a) the physical properties of the tractor;

(b) the power of the engine, and its stationary outlets—the belt and the p.t.o;

(c) the power on the drawbar when working on a formalised test surface or track;

(d) the reliability of the tractor when running under test, and its condition after the test.
