Work Completed
Got wifi working on Pi
- streamed video from logitech webcam to isaac's computer over wifi using mjpg-streamer
Camera
- Logitech C920 camera now fully works through GRIP on the RPi2, connected to RoboRio via eithernet. Robot code successfully pulls contour values from images via NetworkTables!
- For mjpg-streamer on Pi:
- mjpg_streamer -i "input_uvc.so" -o "output_http.so -p 8080" (-b)
- ^ streams to :8080/?action=stream
- optional -b for background
- if fails check to make sure ~/.bashrc is running
- then run GRIP
Other:
- made portable target with retroreflective tape
- planned electrical parts with cad team
- researched network tables
- adam updated all the python libs and stuff for the robot
