Eclipse Flying

The Nimbus Lab spent from early morning until sunset last Monday, Aug 21st doing atmospheric profiling flights to determine the impact of the Eclipse on weather patterns. These were collaborative experiments with Dr. Adam Houston from UNL Earth and Atmospheric Sciences, Sean from NOAA, and Dr. Jamey Jacob from Oklahoma State University as part of […]

New Equipment: EyasSat Nanosatellite CubeSat Hardware Emulator

The NIMBUS lab has acquired a new tool to for our research, a CubeSat hardware emulator manufactured by EyasSat. This emulator will enable the NIMBUS lab to design and perform experiments in a new environment: Space! Initial planned experiments include: design and testing of new attitude control laws, efficient allocation of computational resources through advanced […]

Cyber-Physical Co-Regulation of UAS

Among our current interests at the NIMBUS lab is creating a dynamic flight simulator, for drones, to be used as a test bed for control software designed for autonomous flight. The simulator is written in MatLab and will be used in the lab to test control algorithms and as well as new control techniques in […]

Evaluating RTK GPS for UAV

Background: Real Time Kinematic (RTK) Global Positioning Systems (GPS) have been around since the late 1990s. RTK GPS offers centimeter level precision versus meter level precision of normal GPS. RTK GPS’ that can reasonably fit on an Unmanned Aerial Vehicle have been available since late 2013, and we decided to explore how ready and powerful […]

We are looking for a Lab Manager!

We are looking for a part-time lab manager. The primary duties for the lab manager include preparing and maintaining equipment, refining scripts and models, giving tours, building and running demos, enforcing certain processes, etc.  The person we are looking for needs to have technical experience relevant to the lab including basic programming skills and exposure […]

Summer 2016 Field Experiments

We conducted a whole lot of field experiments over the summer. First, we did two prescribed burns and a number of tests of the systems (without igniting fires). Here are a couple of videos to check out: We also conducted a experiments at the University of Oklahoma as part of the Cloud-Map project we are involved […]

Prescribed Fire Updates

This is one of my favorite pictures after our successful prescribed burn at Homestead National Monument, which shows all the people that were involved in the first ever prescribed fire ignition on public land by a UAS (can you guess which side is the fire crew and which side is us?). Recently, we had an article […]

Exporting ROS Bag Files to Matlab, v2.0

A while ago I wrote a post about bag2csv, which is a tool I wrote to import data from ROS bags to Matlab workspaces. This tool first converted the bag data to CSV files, and then read the CSV files into Matlab. We’ve discovered a lot of shortcomings to this approach since that post was written, and as […]
