Movies from Paper with Compilation of All

Supplementary Movie 2 Full_Video_s1
A side view of an American cockroach, P. americana, traversal a 3 mm crevice. Playback sequences are real-time and 10× slowed.

Supplementary Movie 2 Full_Video_s2
A side view of an American cockroach, P. americana, crawling in a confined space at 12, 9, 6 and 4 mm crevice heights. Playback sequences are real-time and 20× slowed.

Supplementary Movie 3 Full_Video_s3
A side view of an American cockroach, P. americana, undergoing a compression materials test in a specially constructed apparatus attached to a materials testing machine. Playback of compression sequences are real-time while the recovery sequence is 20x faster.

Supplementary Movie 4 Full_Video_s4
A demonstration of the compliance of our robot’s shell, passive sprawling mechanism of flexible spine and a side view of our robot prototype running unrestricted and crawling in a confined space at 35 mm crevice height. Playback sequences are as indicated in video.
