Stewart平台是一种典型的并联机构，广泛应用于六自由度飞行模拟器中。它在动物中很少发现，也从未被报道过调节和控制生理活动。现在，在蜜蜂中发现了类似的Stewart平台结构(膜翅目：蜜蜂科：意大利蜜蜂Apis Melvena L.)腹部来解释其三维运动。用体视镜和扫描电子显微镜观察蜜蜂腹部的内部结构。实验观察表明，肌肉和节间膜连接着胸骨和胸骨，保证了蜜蜂的腹部运动。从力学角度来看，Stewart平台是由蜜蜂腹部的侧向连接结构演化而来的，而胸骨和胸骨间的节间肌肉是Stewart平台平面之间的致动器。这种非同寻常的结构为蜜蜂完成各种生理活动提供了各种优势。这种等效的Stewart平台结构也可以用来说明其他昆虫的腹部与节段性腹部的灵活运动。
The Stewart platform is a typical parallel mechanism, used extensively in flight simulators with six degrees of freedom. It is rarely found in animals and has never been reported to regulate and control physiological activities. Now an equivalent Stewart platform structure is found in the honey bee (Hymenoptera: Apidae: Apis mellifera L.) abdomen to explain its three-dimensional movements. The stereoscope and scanning electron microscope are used to observe the internal structures of honeybees' abdomens. Experimental observations show that the muscles and intersegmental membranes connect the terga with the sterna and guarantee the honey bee abdominal movements. From the perspective of mechanics, a Stewart platform is evolved from the lateral connection structure of the honey bee abdomen, and the intrasegmental muscles between the sternum and tergum function as actuators between planes of the Stewart platform. The extraordinary structure provides various advantages for a honey bee to complete a variety of physiological activities. This equivalent Stewart platform structure can also be used to illustrate the flexible abdominal movements of other insects with the segmental abdomen.
