About

It is very simple demonstration how to use Carambola as rover platform with video feedback. It could be nice toy to build in couple of hours.

Hardware

I used very simple hardware setup. Key components are motor controller, 47:1 gearmotors, wheels, UVC webcam supported by mjpg_streamer and of course Carambola.

Connection

Building system

passwd root
opkg update
opkg install mjpg-streamer
config mjpg-streamer core
      option device           "/dev/video0"
      option resolution       "400x200"
      option fps              "25"
      option port             "8081"
      option enabled          "true"
opkg install ser2net
2002:raw:600:/dev/ttyS1:115200
ser2net
exit 0
reboot

Testing

ToDo

This quick example illustrates how to interface motor controller and webcam. Further you could connect these items to build autonomous vehicle.
