-tell when it hits the surface from the job and drive out of a capsule
-attach a camera to a servo for a panoramic to take a picture of the capsule
You want to take a picture of the capsule from the capsule?
Me and a group of friends are building a rover for a school project. What I am confused about is what specific parts I would need to complete it. We want it to:
-pick a path away from the capsule (ping sensor)
-2 whell drive
We want this to fit in a 150x100x100 mm box, we can expand it a bit more if we have to. We were thinking of using a Arduino Uno R3 or going smaller and maybe a Arduino mini. Thanks!

Even with a parachute, you might not land upright!). Probably a 3-axis accelerometer would be best for this, that way you can measure if you are still in motion, also when you "hit" the surface (a large jolt in acceleration opposite - I believe? - to "down"). You might also want something on the capsule that can tell when surface contact has been made (maybe a simple switch?). Or - if acceleration measurement is too much, look for a "caged ball" sensor to determine "orientation". Using one of those, and some kind of contact sensor switch on the capsule, might be enough to tell you "I am down, and I am upright - open pod bay doors, HAL"...
