A unique form of locomotion in a stomatopod—backward somersaulting

  title={A unique form of locomotion in a stomatopod—backward somersaulting},
  author={Roy L. Caldwell},
Of the diversity of forms of locomotion evolved by life on Earth, one that seems not to have developed to any great extent is rolling or somersaulting. Many cultures claim the existence of ‘hoop snakes’ that grasp their tails in their mouths and roll downhill, but no known snake can perform this feat1. Furthermore, although at least one spider (Hamilton, personal communication) when disturbed forms its body and legs into a sphere and rolls down sand dunes, I have been unable to find examples of… 

Wind-Powered Wheel Locomotion, Initiated by Leaping Somersaults, in Larvae of the Southeastern Beach Tiger Beetle (Cicindela dorsalis media)

The present study suggests that the negative effects of beach traffic may be indirect, preventing larvae from escaping from predators using wheel locomotion by disrupting the flat, hard surface necessary for efficient wheeling.

Maximum relative speeds of living organisms: Why do bacteria perform as fast as ostriches?

The maximum speed is studied and its order-of-magnitude scaling with body size is studied, from bacteria to the largest terrestrial and aquatic organisms, to imply a locomotor time scale virtually independent on body size, anatomy and locomotion style.

Jumping robots: a biomimetic solution to locomotion across rough terrain

The authors present two new biologically inspired jumping robots, Jollbot and Glumper, both of which incorporate additional locomotion techniques of rolling and gliding respectively, and demonstrate that this can be achieved through optimization and careful materials selection.

Unlike rolling stones: not every Myrmecina species actively rolls away from danger (Hymenoptera, Formicidae)

Ecological, morphological, and phylogenetic constraints may have determined the lack of a developed active rolling escape-strategy in M. sicula, which has never performed the active rolling behavior that is readily exhibited by M. graminicola.

Righting kinematics in beetles (Insecta: Coleoptera).

GoQBot: a caterpillar-inspired soft-bodied rolling robot

A novel rolling robot that closely mimics caterpillar rolling, and demonstrates how morphing can produce new modes of locomotion, and mechanical coupling of the actuators improves body coordination without sensory feedback.

SomBot: A Bio-inspired Dynamic Somersaulting Soft Robot

A bio-inspired dynamic somersaulting soft robot (SomBot) with ultra-fast moving speed (maximum speed is over 0.94 m/s) and a much faster speed than the reported fast-moving soft robots, which demonstrates the dynamic somesaulting mechanism has great potential for designing soft locomotion robots with superior mobility.

Scarab beetles at the interface of wheel invention in nature and culture

It is suggested that an increased opportunity to observe pill rolling scarab beetles has inspired humans to invent the wheel.

Rolling away: a novel context-dependent escape behaviour discovered in ants

The discovery of a peculiar strategy adopted by Myrmecina graminicola, a cryptic ant living in forest floor, which is the first example of locomotion by rolling discovered in ants and one of the very few among animals, offering opportunities for multidisciplinary research on the adaptations and biomechanics underlying it.


Stomatopod Crustacea of the Western Atlantic

The stomatopod fauna of the western Atlantic is far richer in number of species than previously believed, and studies on the systematics of the group on a world-wide basis are considered, with present emphasis on American species.
