Interim Design Review Presentation

Transcript: We identified a unique connection between a new and exciting industry trend, Quadcopters, and renewable solar energy. We saw that the main limitation of Quadcopters was the short flight time and realized that we could utilize solar energy through the use of a custom base station to extend their operational time. Our main goal became to create a custom Quadcopter optimized for long FPV (First-Person-View) flights and a solar powered base station that would increase the portability and usability of the Quadcopter. Software: Updated firmware PID tuning Marketing -Facebook page -YouTube Channel -Website Methods/Design Key -S Start condition -Address 7 bit address -R/W Read/Write bit -ACK Acknowledge Signal -P Stop Condition Software Diagrams & Analysis Hardware: Frame Barometer Landing gear FPV system -Receiver/Transmitter (910Mhz) -Camera -Antennas -Our first FPV flight. -Stable PID settings that allow for smooth, controlled FPV flight. -Custom reinforced Aluminum frame; added stability and durability. -Promising video transmission -Marketing Q.U.A.C.S. Website Q.U.A.C.S. Facebook Page The IT Crowd Proudly Presents: Thank you! Quadrotor Unmanned Aerial CopterCam System Technical Development Cost Analysis -QUACS Development Team Quadcopter To test the stability of the Quadcopter, we created a custom testing platform. This platform allowed for free rotational motion, while restricting altitude and horizontal movements. This platform allowed for sensor testing, PID coefficient testing, and frame rigidity testing. We utilized this platform to adjust the PID coefficients to suit our preferred flight characteristics. Hardware Diagrams & Analysis Solar Charging Circuit -Regulating -Charge Rate Why we chose this project: Marketing ...Stay tuned afterward for more action! We have already officially met one of our three design objectives: We have obtained stable enough flight to provide a clear video feed. Vibrations do not effect the camera output. From the testing we were able to conduct, we were able to achieve clear video transmission greater than 100m. However we have not tested this live on the Quadcopter. Our solar cells were not able to produce enough current to meet our design objectives. However, we have found a solar panel that we can purchase that will fit our needs. Our next session does not include an official 'Senior Project' class; however, we will devote time to perfecting our platform and becoming better pilots. We will use this time to accumulate data and video footage that reinforces our project's applications in society. We will ensure that we have the system completed by our final session so that session can be devoted to final presentation preparation. More Test Footage! ECET493L Interim Design Review Presentation Final Cost Breakdown Important components -Three-Axis Gyroscope -Three-Axis Accelerometer -Digital Motion Processor -Reduces Load on microcontroller -ADC -I2C Master/Slave Serial Interface -2 bytes for each sensor's x, y, z -Aditional Sensor -BMP085 Barometer -SCL and SDA Management To test the power output of our solar base station we used the Multimeters and Power Supplies provided by the E-Lab. We tested to see how much voltage and current we could get from our solar panels under different light sources. We also tested the video transmission range of our video transmitter by measuring the distance we could move the transmitter away from the receiver while still having a clear video image.

Milestones & Achievements Quadcopter Solar Panel Specs -Power (Pmax) : 10W ;can be used in single-module and multiple-module systems Maximum power voltage ( Vpm ) : 17.5V ;Maximum Power Current: 0.57A Cable lengths : 3' Dimension 13 3/4 x 11 x 2/3 in Open circuit voltage ( Voc ) : 21.95V The base station is entirely analog and has no software! However, We would like to take this opportunity to mention our marketing strategies: Q.U.A.C.S. References Next Session 910Mhz Inverted-Vee Antenna This custom made 910Mhz Inverted-Vee Antenna was designed to be used with our 910Mhz video transmitter and receiver. Unfortunately, we have yet to be able to test it. It was designed using the following formula: Quarter Wave Assuming 95% Velocity Factor Length in Inches (for 18AWG wire) = 2779/Frequency in MHz 2779 / 910Mhz = 3.053 inches Facebook Demographics Facebook Reach PID Diagram
