脚趾的精细结构造就了壁虎非凡的攀爬能力。研究壁虎足在不同尺度上的形态特异性，为揭示壁虎运动能力提供了解剖学信息，为壁虎机器人足的发展提供了理论依据和数据支持。在研究过程中，我们使用Keyence(VHX-600E)数字显微镜系统对壁虎的前足和后足进行了不同尺度的观察和拍摄。计算足趾刚毛板数后，用图像处理软件进行图像处理，计算足趾面积和足趾面积。结果：前足和后足第一足趾上的绒毛片数差异无统计学意义(P>；0.3)。同样的情况也出现在第二和第四个脚趾上。前足与后足第三趾刚毛板数有显著差异(P<；0.005)，前足第五趾与后足第五趾亦有显著差异(P&t；0.01)，前足与后足总面积差异极显著(P<；0.01)。前足第一趾面积与后足第一趾面积差异有统计学意义(P<0.005)，其余四趾面积与后足面积有极显著差异(P<0.05)。研究结果表明，在前足和后足以及相应的脚趾的设计上应采取具体的设计。
The fine-level structure of toes contributes to the extraordinary climbing ability of G. gecko. Research on the morphology specificity of gecko feet at different scales provides anatomical information for revealing geckos motor ability and provides theoretical basis and data which can support the development of the robot gecko feet. During the research, we used KEYENCE (VHX-600E) digital microscope system to observe and photograph the forefoot and hindfoot of G. gecko at different scales. The image processing as well as calculation of foot area and toe area was done using image processing software after the number of toe setae lamella was counted. Results: there was no significant difference between the numbers of setae lamellae on the first toes in both forefoot and hindfoot (p>0.3). The same situation also appeared in the second and forth toes. Significant difference between the numbers of the third toe setae lamella in forefoot and hindfoot was observed, the same situation also happened in the fifth toes of the forefoot and hindfoot (p<0.01), the difference between the whole area of the forefoot and hindfoot was extremely significant (p<0.005). The area of the first toe in forefoot was different from the corresponding one in hindfoot (p<0.05), while the areas of the other four toes were extremely significant from the corresponding ones in hindfoot (p<0.005). The results of the research suggest that specific designs should be adopted in the devisal of forefoot and hindfoot as well as the corresponding toes.
