Video Description
For this test, yaw DoF was constrained using mechanical stop which was a simple string rotated around guide rails and center shaft. Signal was sent via Arduino UNO. An aluminum clamp was installed so that helicopter would stop rising before it hit ceiling. Position data was recorded via rotary optical encoder. Test was performed on June 8th, 2012 at UCSD sensor lab EBU2 131 and was recorded by Erik.
Before test started, we ran into several problems such as setting throttle range for ESC (Electronic Speed Controller), wiring and communication with Arduino. However with the help of Steve Roberts, we managed to solve all the problems and get the motor running and lifting.
Video Description
The first video shows the test done to check binding for main shaft when a 5lb load is applied at the end of the shaft. No binding issue was observed during the test. The second video shows another test to check binding. This time the end of shaft was pressed down manually. However the shaft did not bind in the collar. Both videos were recorded by Daniel on May 1st, 2012.
Build this site up during the project so you include early concepts and show how they progress.
Most recent material should be towards the top of this page.
Include a copy of the images used on the front page here as well.
Provide captions for each figure
Also, upload high resolution photos and CAD images in High Res. These files should be available for publicity events where high quality printouts or web images are needed.
