Meeting Summary:
Autonomous:
Range test last Saturday. Fully charged battery only lasted 25 minutes. Approx .3 miles
Worked on new wiring system to make more concise and organized
Need baseline for starting values to calibrate the autopilot
Still in need of a test location on ISU property
Next week expecting to receive parts to test on bread board
Camera:
decided to continue with last years camera
Concept for using bearing and gear system to rotate camera
Transmitters have narrowed the search to two options
HAM Radio licensing
Need more than a licensed technician
Need a video overlay board
Jason and Matt S. plan to take the test
UAV/Launch
Field test was accomplished last week (tennis balls and push rod were launched)
Push rod was broken – develop reinforcement or new design
Need to order replacement leg brace
Some things were forgotten when doing the test launch – make a check list
A 1⁄2 model wing was created and another one or two will be made this coming week
1⁄2 scale models for CNC machine were completed
Ask around for the sting mount?
Make plans for trip to Hobby Haven to buy new servos
Pete Sherman Suggested looking into a book called Aircraft Simulations by Stevens and Lewis for Dynamic models
Present - all but those absent
Absent -Daniel Jason
Agenda -
Subgroup updates in the past week
Subgroup plans for the coming weeks
Assign items to members of each subgroup
Accomplishments-
Field test for range (not successful further proof we need more battery power)
Test launch complete for push rod and tennis balls
1⁄2 scale Solid works model complete
1st 1⁄2 scale wing completed
Action Items -
Find flight field (ISU research fields) - Jason E
Make a google page for HAM license information - Jason E
Improve and send Matlab code to Pete S – Jordan
Make more wings - Peter Eric Scott Aidan (and others who want to join) 27 Tuesday 9am
Make launch material check list – Tyler
Dynamic Model – Scott , Aidan
Weekly Report for Matt Stemper
Assigned:
Find starting values for PID loop coefficients and continue model of control system.
Accomplishments:
I have a first draft of the control system modeled complete in Simulink. All of the PID loops are in the model with the feed forward components. I also worked on range testing and launch system testing.
Next week:
Improve the Simulink model by focusing on the inputs and outputs of the loops. I need to also still find the PID loop constants to start with and prepare myself to take the technician's level HAM radio test.
Hour breakdown (8 this week):
3.5 hours- range and launch system testing
3.5 hours- Control system modeling
1 hour- meeting
Cumulative hours: 41.5
Weekly report for Timothy Jacobs
Assigned:
Order parts, Work on PCB layout
Accomplishments:
Parts have been ordered and the PCB layout is in progress. I also looked into the how to tune the PIDs.
Issues:
PCB layout software does not always work
Next week:
PCB layout. Range test.
Hour breakdown:
4 Hours- PCB layout
2 Hours- Parts
Hours this week: 6
Cumulative hours: 51
Weekly report for Jason Ekstrand
Assigned:
Research video transmitter options and regulations
Accomplishments:
I found 2 transmitter options (one at 900 mhz and one at 440 mhz), and found what we need to be doing in order to run things legally
Next Week:
Work on studying for my HAM Technician certification, and talk to some people about when we could have a test.
Hour breakdown:
2 – HAM research
6 – Transmitter research
Hours this week: 8
Cumulative hours: 26
