AT 309: Introduction to Blogger

 Introduction

 I am Nicholas Hansen, a junior majoring in unmanned aerial systems and minoring in design and aviation. I am a teaching assistant for Dr. Damon Lercel and William Weldon, and assisting in the AT 109, UAS design and construction and AT 209, Civilian UAS, Classes currently, and I have also assisted in AT 119, UAS inspection and repair, in the past. I am also Vice president for the Purdue Drone Club. I operate for Purdue’s Agricultural Research Center, flying DJI M600s and M200s with RGB, Hyperspectral and LiDAR sensors. I have been flying drones since 2010, the first drone that I flew was a Parott AR drone, and since 2012 I have been building and developing many different platforms, fixed wing, multirotor and VTOL. 

For this class AT 309, introduction to uas sensors, I was required to create a blog where I will post my lab reports much like my previous courses. To begin this blog we started by looking at others blogs and seeing what worked and what did not, which will help me to write a better more informative blog. 

Methods 

I reviewed 5 different blogs from former AT 319 students, and used their blogs to give me insight on how to write a better blog.

Ricky Vogel, https://rvogeluas.blogspot.com/

Ricky’s Blog was very though and had minimal to no spelling or grammar errors that I could find. Some of the attention to detail came from how the blog is broken down, it is almost always in a standard format of Introduction, Methods, Discussion. I really liked that the blogs had the figures well placed labeled and they had figures and references. I also liked the clean over all look for the blog and making sure that each figure can be directly visible if its referenced in the text. 


Kaleb Gould https://kagould.blogspot.com/

Kalebs blog on Orth mosaic generation of the football stadium, was well done. It had an easy to fallow format, starting with an overview then diving into more detail in how the data was captured, and with what platform it was captured with. He also does a good job of describing the figures in his writeup, but his captions could use a little more information. His figures in his blog on the use of PIX4d for point clouds, orthomosics and DSM provided a good amount of information in a better format than summarizing the output log from PIX4D

Nick Dayton https://ndayton.blogspot.com/

First off Nicks blog was hard to fallow as there was not a use of headers for each section so I could not tell if I was reading an introduction or just jumping into the research. He also did not provide any figures for his images, and thus did not have any captions to better explain the images. The general overview of the blog is fine, but the lacking in details makes for a much more difficult experience for the reader. 

Jesse Giampalol https://jessegiampaolouas.blogspot.com/ 

Jesse’s blog was well put together it had good headings, and even separated the 2 parts of the comparison of ArcGIS Pro and Pix4D. One thing I noticed was there were a few grammatical errors, and a bit of inconsistency in the figure citations when referring to a figure. Overall, the blog was well put together and had all the information needed, as well as being easier to understand with the proper headers and figures. 

Jeff Hiens  https://jjhinesuas.blogspot.com/

Jeff’s blog was a bit of a mess, I did not like the side panel archive as it distracted from the content. I can see that he had some technical issues with the blog, the assessments did not have a lot of information, and the maps tables and figures only had one figure with no way to easily decipher which lab it was from. 

Discussion

After reading a few of the blogs from Dr. Hupy's AT 319 class I can more clearly see the expectations of the blogs as well as gaining some insight on how everything from spacing to formatting can improve the readers ability to process the information from the blogs.

Setting up a vtol in mission planner

Image
Introduction Setting up a vertical take off or landing (VTOL) uav is one of the more complex aspects of mission planner, for programming a pix hawk flight controller. The vtol that will be set up in this blog is a 2.5 meter wingspan, custom quad rotor, with all four motors tilting uav. Figure 1. A screen capture of the firmware installation page of mission planner  To begin install arduplane on your pixhawk, using the install firmware page in mission planner, figure 1 shows the pop up window that should appear. Next once the firmware is installed go through each of the settings of the mandatory setup, including the accelerometer calibration, compass calibration and the radio calibration, but skip the servo output for now. The next step is going to the full parameter list under the configuring and tuning tab, and enable Qplane, which stands for quadplane, and allows for all the vtol settings to be shown. Then the frame style and setup has to be configured, these have t...

DoakBurn (Again)

 Introduction The goal of this lab was to use ArcGIS Pro to view the various band stacks of orthomosaic imagery and a normalized difference vegetation index (NIVD). The data was collected by Dr.Hupy, William Weldon and Zack Miller, and the data was of a controlled burn with multispectral cameras. Methods The methods of this lab was to look at the areas that were burned and compare them to the areas around them that were not burned. This could be done with RGB, or band stacking for the imagery, which allows the ability to see things that are not able to be seen with the human eye.  Metadata from the Flight Vehicle: Bramor PPX Sensor: Altum Flight Number: 2 Takeoff Time: 12:18 Pm Landing Time: 12:35 Pm Altitude (m): 121 Sensor Angle: NADIR Results  The data collected with the band stacking shows the differences between the pre-burn and post-burn data. Figure 1,2,4,5,6,9 are in a 5,3,2 band stack, meaning the red represents near-infrared, the green represents th...

Designing a Vtol Mechanism from scratch

Image
Introduction A project that I have been working on needed a Vertical takeoff or landing (VTOL)  tilt mechanism for the the front 2 motors, so here is how I went about designing and testing it. It can be challenging to hand launch a twin motor plane as you have to worry about both prop disc areas, while managing controls, and adding a vtol system can allow for operations where a wheel based takeoff is not a possibility  The specifications of the propulsion system are a Emax 2213-935KV brushless motor, that spins a 8045 prop, with a spider 20apm opto esc, using a 4 lithium polymer cell battery. This power systems is typically used in quad copters such as a dji flamewheel 450. The servos for tilting the motor varied depending on the design of the tilting mechanism. Figure 1. A dji flamewheel 450 quadcopter, with a propulsion system similar to the VTOL's system Goals  The goals of this project was to be able to develop a vtol tilt system for a uav that ...
