Work Completed

  • Found a way to monitor the CPU usage on the Pi.
    • type in 'top'
  • Isaac is working on python script to export cpu usages to network tables
  • Started outlining some code for the new robot but it is possible that Adam was already doing that in eugene_x.
    • what I tried to do is commented out at the end of teleop.py in short_e code
  • Made some swag cheat codes for the pacman game
  • Changed the Grip file named test_ip2.grip on the computer but not on the pi
  • Fixed idiocy from yesterday
    • "I dont want to explain" -Isaac

 

Challenges

  • Unistalled pacman rip my friend
  • other subteams were distracting
    • all they did was kick balls and play cards
    • we were slightly drawn to their lack of work
  • When we ran grip and printed values from the pi and the camera there is a very significant delay.
    • Up to 7 seconds between when we remove the retroreflective tape and when the values for width disappear
    • Isaac believes that it is simply the grip file so make sure to change it with the new version on the desktop
    • This might be a bandwidth issue and we should do testing on whether it is the pi-->roborio or roborio-->computer

Work for Next Meeting

  • OPEN GITHUB AND SYNC, even if you're not sure you'll be modifying robot code.  When meeting is over, COMMIT then SYNC AGAIN.  Just do this every meeting.
  • Find best way to see/modify camera settings.  Play with brightness/exposure/etc. to get the best isolation of targets in imagebefore GRIP gets ahold of the stream.  Then adjust GRIP file to make the best use of that.
    • On some websites, they connect the video to the HSV filter twice so that there are two intervals for each. Might want to check this out.
  • Get GRIP file to deploy like robot code, from DS->Pi, likely via PSCP & upgrades to our fancyier Wing script
  • Get mjpeg-streamer & GRIP to run when robot code starts, die when disabled or match over
  • Find good settings for mjpg-streamer
    • keep optimizing
  • Outline new robot code, using WPI commands style
  • Get second RPi spun up and tested with GRIP, mjpeg-streamer, etc. for practice bot
  • Check on spike supply and maybe order more
  • Look for velcro to buy thomas want various strengths/sizes
  • Work on wiring of RGB LEDs
  • Look at Nolan's new and improved controls list
