This is a bit more background on how these robots were modeled.  And it is fairly nimble for a simple kind of bot in that it can switch between two types of modes easily:

The most recent of these origami robots or “robogamis”, Tribot, has been unveiled at the International Conference on Intelligent Robots and Systems (IROS). Tribot’s gait pattern is modelled after inchworms, but what makes it unique is its gait mode: it can simultaneously switch between crawling and jumping, which means it can jump over obstacles and then resume moving forward. Tribot is two centimetres tall, weighs 4 grams and has a T-shaped structure with three legs. “This unusual robot can jump up to seven times its height, and it does not need to be reset between jumps,” said Paik.

What tpes of applications will they use these things for?  Feel free to comment with your theories!
