webapps/robots/robots/sk8mini/awacs/cam.ino

• empty setup() and loop() methods
• not used

robots/sk8mini/awacs/example/CameraWebServer/CameraWebServer.ino

• modified to connect to wifi as access point
  • connected as station: slow
  • connected as access point: less slow
• implement webserver commands
  • /index.html
  • /capture
  • :81/stream

cam.py

• connect to the wifi
• call the webserver on the awacs
• use the esp32-cam “capture” command
• receive the returned image
• save it to hard disk

two decisions:

• framesize
• lens
  • fov
  • distortion
  • clarity
  • color
