Some apes (especially gibbons), and perhaps some ancestors to humans, used special forms of arm-swinging to move among the tree branches. Brachiation is the term given to the most specialized form of such suspensory behavior. In attempting to understand the mechanics of brachiation, it has been modeled as the movement of a passive pendulum. However, this likely does not accurately represent the actual mechanisms by which gibbons, for example, move through the complex and obstacle-ridden world of tree branches. There be active propulsive forces to modulate speed and direction. This research project will identify the muscular mechanisms the gibbon can use to maneuver and propel itself, and what strategies other than pendular motion exist for minimizing energy expenditure in brachiation. To date, research in this area has been limited by the lack of a method for directly measuring the kinetic reaction forces produced by an animal subject during locomotion. In this study, a newly developed 6-component force/torque transducer will be attached to a handhold used by brachiating animals. Combined with simultaneous video analysis,iti will be used for a comprehensive study of the mechanics of brachiation.

一些猿类（特别是长臂猿），也许还有一些人类的祖先，使用特殊的摆动手臂的方式在树枝间移动。腕动是一个术语，指的是这种悬吊行为的最特殊形式。在试图理解的机械臂，它已被建模为一个被动摆的运动。然而，这可能并不能准确地代表长臂猿的实际机制，例如，通过复杂和充满障碍的树枝世界移动。有主动推进力来调节速度和方向.这项研究项目将确定肌肉机制的gibrant可以用来操纵和推动自己，以及什么策略以外的摆动运动存在最小化的能量消耗在臂。迄今为止，这一领域的研究一直受到缺乏直接测量动物受试者在运动过程中产生的动力学反作用力的方法的限制。在这项研究中，一个新开发的6分力/扭矩传感器将被连接到一个用于臂式动物的手柄。结合同步视频分析，iti将被用于臂化力学的综合研究。
