The proposed research will examine six-legged animals (insects) as first step toward testing whether or not design solutions exist that are general features of legged, terrestrial locomotor systems. Results will be compared with our previous research on eight-legged designs (crabs) and published work on quadrupedal and bipedal mammals. Using newly developed, miniature force-plate the applicant proposes to examine mechanical energy fluctuations and stability. Both aerobic and anaerobic energy cost will be measured using miniature treadmill. The applicant will test whether or not: (1) the use of an inverted pendulum mechanism during walking is a general feature of legged locomotor systems, possibility relating to energy conservation; (2) the use of bouncing mechanisms during high-speed locomotion is a general feature of legged stress; (3) major variations in body form of legged locomotor systems affect mechanical power output which may determine metabolic energy cost; (4) stability is the foremost design criteria in small legged terrestrial locomotor systems independent of body form. The comparison of a 6-legged design with 2-, 4-, and 8-legged animals will provide the foundation for the future investigation of the impact of variation in body form on terrestrial locomotion.//

这项拟议中的研究将首先检查六条腿的动物（昆虫）， 测试是否存在设计解决方案， 有腿的陆地运动系统的一般特征。 结果将 与我们以前对八足设计（螃蟹）的研究相比， 并发表了关于四足和双足哺乳动物的研究成果。 使用新 申请人建议检查的开发的微型测力板 机械能波动和稳定性。喜氧和厌氧 能源成本将使用微型跑步机进行测量。 申请人 将测试是否：（1）使用倒立摆机构 在行走期间是腿运动系统的一般特征， 与节能有关的可能性;（2）使用弹跳 在高速运动的机制是腿的一般特征 应力;（3）腿运动系统的体型的主要变化 影响可能决定代谢能量的机械功率输出 （4）稳定性是小腿式起重机的首要设计标准。 独立于身体形态的陆地运动系统。 比较 6条腿设计的2条、4条和8条腿动物将提供 为今后调查变化对环境的影响奠定基础 在陆地运动中的身体形态。//
