ROS on read-only filesystem

I am using an Odroid U2 on a robot and from time to time it can occur that this device (running Ubuntu 13.09, a Linaro distro) becomes read-only after an incorrect shutdown (power is cut from the device). The usual fix for this is to remount it as read-write or execute fsck.ext4 to fix any incorrect inodes etcetera on the SD card.

I was wondering though what the possibilities were to make sure this cannot even happen. Preferably I would be able to cut the power at any given time without corrupting the SD card. I imagine that a read-only file system to begin with could work, as nothing needs to be written anyway so no corruption would occur. Is this possible? Does anyone have experience with this setup? If so, if you can point me in the right direction, that'd be great :)

Best regards, Hans
