It's a nightmare scenario. You're on an ambitious mountain hike when you get lost, injured or stranded.

Not only do you get the snacks, medicine or water it's carrying, you can eat the wings to tide you over until the rescue team arrives.

The munchable machine is part of a broader project called RoboFood. RoboFood is about investigating edible robots for humans and animals as well as foods that behave like robots.
