摘要或動機

在本研究中,我模仿蟑螂的行走方式,來製作可以在各種地形以不減速的方式前進的機器車。在偶然機會下,我觀察到,蟑螂可以順利爬越米堆,因此對蟑螂的運動方式感到興趣。我用微型網路攝影機拍攝及觀察蟑螂的行走方式。發現蟑螂在快速行走時,是以三隻腳為一組,六腳兩組交互進行前進的動作。由於三點構成一平面,使蟑螂在快速移動時,相當的平穩。我將此原理融入蟑螂車的設計,並根據這個原理,利用舊玩具四驅車改裝成「六驅車」,成功的製作出模仿六足昆蟲行走方式且可以在各種地形順利前進的機器車。為了更客觀的比較,我應用樂高積木的馬達組合,製作了一部純轉動前進的六輪傳動車,及另一部轉動兼走動的六輪蟑螂車。並利用微電腦控制兩種車維持相同的驅動速度前進(93.33 rpm),於各種路面實地測試,證實蟑螂車越野的性能的確強很多。未來若可以將六足昆蟲行走方式的概念應用到汽車製造,車輛的越野性能必然大幅提昇。\r

In this research, I developed a six-wheel driving vehicle simulating the movement of cockroach. The resultant motion machine can un-intermittedly run on terrains without speeding down. Occasionally, I observed that the cockroaches can crossover a heap of rice. Therefore, I was very interested in and eager to learn how cockroach runs. I recorded the movements of cockroaches by using mini web camera and analyzed the moving characteristics of cockroaches. It was discovered that the cockroach marches quickly by interchanging two groups of foot in which each group consists of three feet. As a table can be supported by three legs, the cockroach runs steadily and rapidly. I have designed a motocross vehicle based on the mechanism of the way that cockroach runs. A six-wheel driving car is constructed by modifying four-wheel driving toy cars. By simulating the motion complex of six-foot insects, the six-wheel driving car turns out to be an all-terrain vehicle. To be more objective in comparison, I built two types of six-wheel driving cars by utilizing the LEGO TECHNIC motor building set: one with regular and synchronous rotation, and the other one with eccentric shaft rotation emulating cockroach marching movement. I applied a microprocessor to control the motors in order to maintain the same driving speed (93.33 rpm) for both cars during the road test. The experimental results show that the proposed cockroach motocross car performs superiorly especially for the rugged terrain. In the future, the off-road capability of a jeep can be improved by introducing the concept of six-foot insect movement to vehicle design.
