... kinetic similarities that may be related to arm swinging. Biomechanics Brachiation Evolution Mechanical flexibility Suspensory locomotion The ability to change locomotor modes by adjusting gait and/or posture is key to movement and foraging success in a complex three-dimensional arboreal...

...John E. A. Bertram; Andy Ruina; C. E. Cannon; Young Hui Chang; Michael J. Coleman ABSTRACT In brachiation, an animal uses alternating bimanual support to move beneath an overhead support. Past brachiation models have been based on the oscillations of a simple pendulum over half of a full cycle...

... to produce a low-cost but effective system. The solutions to several problems in the design of the system are provided, and the functional characteristics of the system are demonstrated using both an inert pendulum and an actively brachiating gibbon ( Hylobates lar ). * Author for correspondence (e...
