Integrated System Build & Test

Your website should document your journey through MSD, so include work-in-progress as well as latest results. Use pdf's for display whenever possible so that information is easily viewable without the need to download files and open applications. (Your Confluence file repository should still contain original editable files).

Team Vision for Integrated System Build & Test Phase

Name	3-Week Plan	Tasks Accomplished

Andy Meyer	Finish OS-related cleanup and integration. Develop (basic) autolevelling algorithm and calibration modes Finish communications infrastructure Wire up a controller	Everything changed from last review - in the mean time, we've had to write an operating system! H o o r a y ! I would be excited if the process had not been so rushed. Work accomplished: - Preempting/Cooperative/Mixed Multitasking Kernel - Marshaled IO called via syscall instructions. - Hardware-accelerated floating point has been added and verified. - Subsystem Integration demo
Piers Kwan	Sensor fusion filter	Sensor fusion algorithm (Mahony Filter) Many python debug scripts for an IMU Calibrated IMU Mock flight control
Sabrina Ly	Integrate servos to the rest of the system Set up drivers to initialize both servos Set up drivers to initialize both escs Integrate escs to the rest of the system	Servos have been calibrated, integrated, and move accordingly Both drivers for servos and escs have been written Not fully Completed: Unable to calibrate escs, as unsure how they have been programmed prior, multiple attempts to set different types of calibration hasn't worked
Ben Palmer	MSD2-43 This task is being carried over from the Subsystem Build and Test Phase. It entails laser cutting the wing ribs from a sheet of Baltic birch. It will also involve laser cutting the legs for the Versa Wing. MSD2-49 This task involves assembling the motor onto the nacelle. MSD2-50 This task involves assembling the nacelle onto the struts along with the ribs. Will be done with Mutahir MSD2-51 This task involves attaching the elevon brackets to the wing ribs. MSD2-52 This task involves assembling the elevons and attaching the elevons to the wings. Will be done with Mutahir MSD2-53 This task involves wiring and attaching wing mounted electronics. As I am wing owner I will oversee and work on this task, but this task is not mine alone, as I am not the electronics owner(s). MSD2-55 This task involves cutting the skin for the wings and affixing it in place.	MSD2-43, Fully Complete All laser cutting has been done. MSD2-49, Incomplete The nacelle is ready to accept the motor, but the motor are currently being assembled onto the versa wing for testing. MSD2-50, Fully Complete The nacelle has been assembled onto the struts. MSD2-51, Fully Complete The elevon brackets are attached to the wing ribs. MSD2-52, Fully Complete The elevon is assembled and attached to the wing via the brackets. MSD2-53, Incomplete This task has been pushed back in favor of focusing on wiring the versa wing (which is, as of time of writing, nearly complete). MSD2-55, Incomplete Sourcing and affix the skin for the conceptual design wings has been postponed as the wiring (MSD2-53) must happen before this step, and that is also postponed.
Mutahir Mustahsan	MSD2-54, MSD-59 This task is being carried over from Subsystem Build and Test Phase involves fully assembling the parachute system and fitting it to the Versa Wing MSD2-49 This task is being carried over from Subsystem Build and Test Phase involves reprinting the motor mounts and securely attaching them to the versa wing using screws or other fasteners. These methods will carry over to the conceptual design. MSD2-50, MSD2-52 These task will be done with Ben	MSD2-54, MSD-59 - Incomplete Canopy has been constructed and stitched together. Bridal not attached as there are issues with adding the tension springs. Also still waiting on spring for canister to come in. MSD2-49-Complete New mounts were printed and changed again. Holes were drilled to attach motors. Part was cut in half again due to propeller interference. Still has to be fully attached to versa wing MSD2-50, MSD2-52-Complete Complete ribs were laser cut and nacelles were attached with the brackets
Atulya John	MSD 2-85 This task relates to the development of PCB based on the schematics that have been developed. MSD 2-78 Place the order for the PCB. MSD 2-75, MSD 2-79 Research the potential issues that could arise while testing the PCB and determine what tests to perform to verify functionality of the PCB. MSD 2-77 Test the PCB and verify that it is working as expected.	MSD 2-85: Fully Complete A PCB layout has been developed. MSD 2-78: Fully Complete Order will be placed once the design has been verified by Prof. Barrios (on Friday or Monday at the latest). MSD 2-75, MSD 2-79: Fully Complete Tests to verify functionality of the PCB are as follows: check for shorts, check for continuity, check resistance between points. MSD 2-77 Will be performed once PCB arrives.

Versa Wing

VTOL landing legs cut from Baltic Birch via the laser cutter.

Slits cut into the Versa Wing's foam core body accommodate the forward-facing motor mounts.

Conceptual Wing

Wing ribs were cut from Baltic birch using a laser cutter.

Elevon brackets being assembled onto wing ribs (foreground), constructed elevon in background.

The elevon has greater rib density than the wing because it will be trimmed up or down into headwind, and therefore will need to be stiffer to be effective.

Photos showing wing assembly process heretofore. The motor nacelle (3D printed PLA) is in black, the elevon servo mount (3D printed PLA) is in red. Struts and axle are carbon fiber.

All else (except for assembly screws) is Baltic Birch wood.

Parachute

The parachute canopy has been put together sewing together the tuelle and nylon sheet at around 56" diameter. Still trying to determine the best way to roll up the parachute to fit inside the canister. The bridal has not been attached as there are some issues with adding in the tension springs. This will be taken care of in the final stages. Also still waiting on the spring for the parachute canister. If the parachute is unable to fold easily into the canister lowering the diameter might be the option or reprinting the canister.

Motor Mounts

Motor mounts were reprinted and holes for the motors were drilled into them. The mounts had to be sliced in half due to continued prop interference despite the reprint being brought on due to propeller interference. The plan with these moving forward is that most likely it will be glued

into the versa wing as we are moving away from using screws
