• James tried to understand the operations behind Arduino (1hr)
• George tried to understand the Raspberry Pi operations (start the program) (4hrs)
• Zimon fixed the broken Night Light shell (3hrs)

Week 5 (Oct.1st ~ Oct.5th)

Wednesday:

• Whole group meet with other groups in Green Hall (0.5hrs)
• Whole group gathered information about how to communicate between Pi and Arduino; how to connect camera, lidar, and encoder (2hrs)
• James worked on relatively complex projects on Raspberry Pi (1hrs)

Output

• James made Arduino communicated with Raspberry Pi (3hrs)

• James and George made Pi communicated with Arduino (2hrs)

• George worked on camera and lidar (4hrs)
• Zimon worked on the encoder(3hr)
• Zimon fixed the Gantt chart (0.5hrs)

Friday:

• Weekly meeting with Dr. Feher and TA David (0.5hrs)
• Divided tasks for next week (0.25hrs)

Next Week:

• Download OpenCV and work on it
• Try to build the car once we get it

Week 6 (Oct.8th ~ Oct.12nd)

Monday:

• Group meeting: discussed midterm evaluation form (1hr)
• Whole group wrote midterm report (0.5hrs)
• George and James downloaded Open CV (2hrs)
• Problem: Have difficulties when compiling Open CV. Several errors appeared: files were truncated and some of them cannot be recognized
• We looked up online for how to debug this problem. The problem was not caused by the lack of storage, since the space left was still large enough. One possible reason is that we downloaded a redundant virtual environment.

Wednesday:

• Group meeting with TA David and Professor Feher (0.5hrs)
• James updated the weekly log (1hr)
• Zimon worked on the encoder by following the Pi Car instruction (2hrs)
• George tried to debug the installation of Raspberry Pi by creating a new virtual environment called "TV" but then failed (1hr)

Friday:

• George figured out how to take pictures by using Python (1hr)
• George and James tried to fixed the Open CV downloading problem by creating a new virtue environment and using new code (4hrs)

• Weekly meeting with Professor Feher: Debugged Open CV; figured out where the pictures were stored in Pi (2hrs)
• By talking with Professor, George and James learned how opencv related to our Picar navigation and some basic knowledge of shape detection.
• George met several failure in opencv compiling (After professor Feher left, error showed again) but george got some ideas to fix it.

      There are some important codes When George were trying to work through the problem:
      1.  mkvirtualenv tv -p python3  (This command will create a new Python virtual environment named tv using Python 3)
      2.  (following code can remove the directory build and create it again )
          rm -rf build
          mkdir build
          cd build

• Divided tasks for next week (0.25hrs)

Goals for next week:

• James works on the motor
• George works on the building the car
• Zimon works on the encoder
