LAB 9 SKYDIO SKILLS FLIGHT

Image
  It was my first time dealing with skydio drone. I was excited to fly this drone, but the weather was not good to fly this last week. Actually, we went to the turf farm three times to do this lab. when we checked out the weather, it was fine, so we decided to go out but when we started to fly, it started raining out of the blue so we had to pack up and reschedule our flight, unfortunately, It happened the other day. We were able to fly it finally yesterday. Pre-flight ​ 1. download the turf farm map in advance 2. verify the latest firmware 3. clean the camera lenses 4. identify potential hazards ​ wind(18mph) -max wind resistance is 25mph but we need to care tree, especially branches- skydio can identify the obstacles but it can't identify small objects such as nets and branches, we need to be aware of that and don't need to fly around the tree ​ 5. set flight boundary and height ​ Flight Maneuvers I can choose two options when I do RTH. one is absolute height behavior, the ot...

UAS Teardown(LAB11)

Image
 My team had a chance to teardown UAS for this two-week lab. It was a lot more complicated than I thought. And some parts of our drone were already missing from the get-go, we were confused at first but we ended up tearing down ours perfectly. This is the process for teardown. Tear-Down Instructions: 1: Take Screws out of the center plastic that holds the harness w/ Phillips screwdriver (4 Screws) 2: Take Velcro Senor Harness off 3: Unplug Wires from Wire Hub 1, 2, 3, 4 , RCN Power2, USB, GPS 1 4: Unscrew/Take off Wire Hub 5: Unscrew and Take Off Plate/Assembly that holds the GPS station 6: Unscrew GPS Holder/Tower 7: Remove GPS sensor from GPS holder/tower 8: Cut the zip ties on the SimonK 30A 9: Cut the zip ties on the propeller arms 10: Unscrew and remove the top and bottom screws from the motor mounts 11: Remove Channel Receiver 12: Unscrew and Remove Prop Arms 13: Separate Central Square Plastic Mounts by removing the screws on both sides and the spacers in-between 14. Unscrew...

Building map with UAS data

Image
Orthomosaic, DSM, DEM DSM stands for digital surface model and DEM stands for digital elevation model.  The main difference lies in the content I captured. DSMs include all surface features (both natural and artificial), while DEMs specifically focus on representing the elevation of the bare Earth's surface, When using the swipe tool to compare orthomosaic and DSM, I could notice how the orthomosaic aligns with the underlying terrain features depicted in the shaded relief of the DSM.  The orthomosaic and the shaded relief of the DSM provide different perspectives of the same area. The orthomosaic will show the actual visual appearance of the landscape, including objects, buildings, roads, etc., while the DSM shaded relief will reveal the underlying elevation variations that influence the terrain's appearance in the orthomosaic. Building the map with UAS data  I made three types of the map(shaded DSM with transparent DSM on top, orthomosaic map and orthomosaic map with a ...
