Amazon recently had a Gold deal of the day on Pelican cases, and I ordered a Pelican 1560 hard case for my DIY time lapse rover.
Using the pick and pluck foam, it provides a snug fit for the Actobotics rover, the eMotimo TB3, and batteries. The case is deep enough to stash any cables underneath the main level of foam. I didn't have a secure and safe way to transport the rover, and it always ended up sitting on top of a pile of stuff in the car. Now I'll know that it's ready to go and won't get damaged during transport.
