Zihao’s E_Portfolio

  Our RV Jet project begins with determining the wiring diagram. Our group was able to generate a detailed diagram of different components.  (Showing as below) After we have done the diagram work, we were able to start to conduct preliminary sensor testing and calibration. A more detailed RV Jet diagram can be found here: ( https://docs.google.com/presentation/d/1enbt0ibUG8IZBt8_CzBwHoZ1PGGlUg2hOg7psIEevVs/edit?usp=sharing ) QGroundControl is the ground station we have decided to use during this class. During our firmware workshop, The primary firmware Ardupilot is somehow malfunctioning, and we end up using the PX4 as our solution. The Skydroid TI12 is our primary controller for the RV Jet, Frequency matched with the aircraft during our lab. (Controller shown below) To set up and calibrate the compass on the RV Jet, On the first several attempts, the software will have errors pop out during our calibration, sometimes it stops halfway, or when we completed, the failure page wi...

  During several lectures on AT 219, we learned some new knowledge and started an assignment regarding how a BLDC (Brushless DC) motor works. The BLDC motor has a stationary stator with coils of wire and a rotating rotor with magnets. The stator generates a rotating magnetic field when electric current flows through the coils, which interacts with the magnets on the rotor, causing it to rotate. With a very high frequency, it produces the right amount of rotations which could power the propellor to produce thrust.  The electronic control circuit determines the position of the rotor and sends signals to the coils in a specific sequence to ensure that the magnetic field rotates in the correct direction and speed to keep the rotor turning.  There are typically three stator coils in a BLDC motor, which are arranged in an upside-down "Y"  configuration.  (As the picture shows below) We have also attached several numbers of buttons, each button them are in charge of a ...

   The final design product of our 3D printing rotor arm:

FROM COMPUTER SKETCHES TO TO BE READY TO PRINT      The top view sketch of our top plate for the rotor arm (Including measures)    The top view sketch of our bottom plate for the rotor arm (Including measures)   The screenshot from NX (The upper plate of out rotor arm design).    The screenshot from NX (The lower plate (base) of out rotor arm design).  Both upper and lower structure are ready to be print out through our 3D Printer. Note:  Specific screw width and length are required. The rotor arm strength hasn't been tested, according to the design, this structure should have a relatively strong and high strenth, But will still need to handle and test with carefully.
