- Ran RPM tests to determine duty cycle to rpm
- Solved issues with 433, communication working perfectly
- Ran RPM tests to determine duty cycle to rpm
- Completed Wildcard video
- Ran into some issues with 433, sent 4 commands got back 3
- Motor speed commands through Duty cycle
- Started working with new equipment, downloaded libraries for 433 and built basic motor commands for continuous motor
- Found that capacitors were the problem on the input to raspberry pi, signal charges up to a point it reads, then it passes the voltage acceptable and then doesnt read anymore
- Ordered new Equipment for demo
- Completed building OP AMP
- DSRC communication still retains errors
- Worked on OP AMP usage to get input signal to have a higher signal initially sent to better differentiate
- Continues problem-solving reliability problems with the communication system using DSRC.
- Continued work on communication system, got it to transmit 2/3 times out 10, not sure if noise or what was the error.
- Received bits, but still inconsistent to pass crucial information accurately.
- Finished rough draft of poster
- Transmitter/receiver work done, changed to using serial instead of pulse width modulation
- Planned a pulse width modulation protocol if serial is not able to fix
- Continued work on poster
- Started working on the rough draft of the poster.
- Worked on transmitter and receiver, and got values to read from a PWM signal, but cannot read exact values from a signal sent at a non continuous signal.
- Worked farther on the transmitter and being able to properly translate bits from transmitter to the Raspberry Pi, got some bits to appear on Pi, but ran into issues with reproducible data
- Servo motor routines created, only ran through 180 degrees so either need a continuous
- Worked farther on the transmitter and being able to properly translate bits from transmitter to the Raspberry Pi
- Worked on finding how to automatically translate numerical values from sensors into ASCII and then send to other Raspberry Pi
- Also got code for returning from ASCII.
- Ran into problems with reading the output response of the transmitter.
- Met to continue work on bit generation and transmission using transmission devices
- Continue working on fan variable speed.
- Motor control, servo motor, lidar distance, change the
- Got square wave generation and transmission from GPIO of Rasberry PI through DSRC transmitter/ receiver
- Used our transmission devices to get camera readings transmitted, also able to send a basic square waveform across from a TX to RX.
- Started developing code and testing a Servo motor with the Raspberry Pi whose speed can be controlled by the value of the LIDAR sensor.
- Updated website with all of the progress made during the last couple of weeks.
- Google Sheets capability for Lidar readings created.
- Worked with TX/RX devices to test connections with Raspberry Pi
- Verify time delay through code, showed that it was under 1 us, that code itself was causing the delay of up to 30 ms rather than the actual clock itself.
- Selected TX/RX to use for DSRC transmission.
- Lidar Testing finished, Linear Regression of data created so that we could add in correction factors and roughly validate correct information
- Continued working on GPS information
- Converted GPS clocking from NMEA Standard information to gather GPS time
- Ran into an issue where only transmitting every .0000 ms
- Most likely going to just sync internal clock to GPS Time after first transmission upon start-up then broadcast time stamps via internal clock
- To Do:
- LIDAR testing to be done
- Clock/Date syncing technique with the Raspberry pi internal clock
- Order our Transmitter
- Met with Prof. Sabau to update on progress and get feedback, as well as confirm questions .
- Set up another meeting for a progress update at the same time next week.
- Met in B123 lab to work on project
- Effectively got LIDAR sensors working minus scaling
- Effectively got GPS information minus translation
- Looked at UDP transmission that was used last year
- Got LEDs working based on LIDAR readings
- Assigned Research Tasks ( LIDAR, DSRC, GPS Clocking Mechanism)
- Updated Website to reflect total teams work
- Received technological components from last year's project: Raspberry Pi's, LIDAR Sensors, and GPS.
- Did more applicable research in DSRC communication
- Brainstormed possible ideas for GPS clock functionality
- Updated website with Research, Block Diagram and TG information
- Met with Prof. Sabau to break tasks for the project between the two teams.
- Researched previous team's work on the project to learn what they were able to accomplish and how.
- Set up a meeting with Prof. Sabau to ask more details about the project and get research materials .
- Had a meeting with all interested members in the project to form two teams for the project.
- Met with Prof. Sabau to learn about the details of the project and the responsibilities/end goal for the project.
