A 15-minute Guide to the Extended Kalman Filter
The extended Kalman filter (EKF)—and other derivatives of the Kalman filter, such as the unscented Kalman filter—are commonly used in sUAS for estimating attitude, position, velocity, wind speeds, and other quantities. Fully understanding the EKF requires technical expertise in several fields, including multi-variate probability theory and non-linear modeling and transformations. This presentation’s goal is to reveal the key concepts behind the EKF without resorting to more than high-school level math and physics. This basic of understanding of what the EKF does, and why it does it, will make using EKFs more accessible both for those wanting to implement EKFs and for those wanting to better understand how EKFs work.

Daniel McKinnon received his bachelor’s degree in Physics and doctorate in Chemical Engineering before co-founding Agribotix after being conscripted by the Denver Zoo to develop a drone for wildlife observation and capture. At Agribotix, he has worked extensively with growers and agronomists to develop both a front-end data collection workflow and a back-end data processing solution that quickly and easily gets valuable actionable intelligence into their hands. These efforts have resulted in the establishment of several concrete value propositions for drones in agriculture as well as numerous lessons for what works and what doesn’t in the field.
UAVs in Agriculture: What do farmers really want? The technology community has embraced UAVs as the solution to all of agriculture’s problems and inefficiencies. Drone-collected images can theoretically lead to reduced fertilizer, water, and chemical application; increased yields; reduced uncertainty; and ultimately increased profits for the farmers. However, while many of these hypotheses may be true, the advanced data currently being collected by drones is far ahead of the adoption of the precision agriculture technologies that enable farmers to act on the data. Through working with farmers and agronomists over the last 18 months, Agribotix has identified the types of data farmers are interested in and a number of different applications for UAV-collected imagery that any farmer can use immediately without strongly deviating from a standard workflow.
Robert Lefebvre is currently a major developer for Arducopter flight control of Traditional Helicopters, and also does work in multicopter dynamics as well. He grew into this role in a less conventional way than most of the other developers, having very little formal computer programming education. Obsessed with RC cars and trucks as a boy, he later started flying RC airplanes as well. These interests led him to pursue a degree in Mechanical Engineering at the University of Ottawa. An old-school mechanical engineer who prefers to get his hands dirty, he loves machines with their complicated workings exposed. He is largely self taught in programming, but appreciates the generous assistance of the other developers as well.
Chris Miser is a Former Air Force Officer with extensive technical, engineering, and program management experience in manned and unmanned systems. He earned a Meritorious Service Medal when forward deployed into Iraq to successfully repair an A-10 downed by missile fire. During his last assignment in the AF he led in-house research and contracted efforts for micro/small UAS development in the Air Force Research Laboratory Munitions Directorate, including development of the first weaponized micro UASes.
In 2011 Chris created Falcon Unmanned and shifted strategic focus to the civil UAS sector. Since that time Falcon Unmanned has become a leader in professional low-cost unmanned systems and has two systems including Falcon (fixed wing) and Falcon Hover (multicopter). Falcon is currently a provider to the Mesa County Sheriff’s Office and the World Wildlife Fund Wildlife Crimes Technology Project, and its crafts were used in the Boulder Floods of 2013 and most recently the Mesa County Landslide.

Jaime Machuca Mercado is the Co-founder and CTO of Droidika. After graduating with a degree in Electronics Systems engineering from ITESM Campus Guadalajara, Jaime went on to work in the automotive industry. During his almost 10 years with Continental Automotive, Jaime led the software development group and was responsible for several projects for Chrysler, Ford, Nissan, and GM in NAFTA before moving to Germany and leading the development of a fully reconfigurable instrument panel used on the Mercedes S-Class ’14.
Jaime is also a very experienced RC Helicopter pilot, flying since the age of 13. In the summer of 2013 Jaime decided to take a risk and mix his hobby with his work, and together with Felix Audirac created a new company dedicated to providing complete solutions with Unmanned Vehicle Systems. Droidika has since provided solutions for cartography, cadaster, search and rescue, and agriculture applications in Mexico.
Comparison of a conventional survey vs. a UAV-based survey in an urban setting: Traditionally a survey of an area has been done by using high precision GPS and by intelligently selecting points in order to recreate the terrain. Today, drones can produce similar results in a much shorter time and in more remote areas than traditional techniques. But how does one compare to the other? What are the challenges faced by drones? and what are the advantages over traditional methods? This talk will present the results of a survey done by traditional techniques, a UAV fitted with a high resolution sensor and a UAV fitted with a low-cost sensor.
Danny Coolahan is an Australian cinematographer and an avid outdoorsman. He recently brought two Iris quadrotors to the Alaksan Chugatch to film a ski movie. Danny operated the vehicles for over one month, flying in a variety of modes and styles to get the best shots possible of the athletes. While there he learned many valuable lessons about operating rotorcraft in harsh winter environments. Danny will be sharing those findings along with a trailer for his upcoming film.
Talk: The highs and lows of flying and falling drones in the Alaskan Chugatch [abstract unavailable]
Andrew “Tridge” Tridgell has been working on free software projects for twenty years, mostly related to system software and networking protocols. Before starting to work on free software full time he contributed to the Samba project (www.samba.org) as a software engineer for IBM, and was a researcher and lecturer in computer science at the Australian National University.
Tridge got interested in UAVs after hearing about a local team entering the Outback Challenge at a meeting of his local maker group, and grew to become lead developer for APM:Plane and APM:Rover. Despite his considerable pedigree, Tridge maintains that his work on APM with the DIYDrones community is “the most fun project I have ever worked on.” He lives in Canberra, and delivered this keynote remotely: Autopilot Development Updates.
