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 […]

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 […]

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 […]

Using rosbag_pandas to Analyze rosbag Files with Python 1

ROS offers great tools to record execution traces using the rosbag command line tool. However, after the data is recorded, quickly extracting the data to perform analysis and produce graphics may be an issue to those unfamiliar with the process. ¬†ROS provides a Python and C++ API to read and write data from the bags […]
