The benefits are many provided that we can identify the principles that constitute the basis for biological-like locomotion. Nature can serve as a template for future designs given that the proper questions are asked and the potential pitfalls are identified. The most important pitfall to consider is the fact that nature does not strive for optimality. Natural designs are built upon their evolutionary history which may impose considerable constraints. Nature s design process works on a good enough basis Vogel 1998 . Direct copying from Nature is likely to result in suboptimal performances rather we should strive for understanding the enabling principles and develop them further to achieve optimal performance Full and Meijer 2001 Meijer et al. 2003 . Biomimetic design requires that engineers and biologists work closely together. To make this collaboration work one should understand that both fields have very different approaches as Vincent 2004 concluded Engineers look at the problem and try to find an answer biologists look at the answers and try to find out what the problem was. The starting point of any biomimetic design should be the function to be emulated. For example for a legged biomimetic robot one would like to emulate the spring-mass and pendulum characteristics that are exploited by animals Full and Koditschek 1999 . The technological aim here is to build mobile platforms that are robust agile flexible energy-efficient self-sustaining self-repairing independent movers no cables as well as adaptable to requirements set by the task and the environment. To this aim it is insightful to study the solutions that animals have found to meet these requirements Full and Meijer 2001 Meijer et al. 2003 . Moving animals exploit various energy-saving mechanisms they .
