The ability to climb walls (or any vertical surface) is a tremendously useful capability for both biological systems and human-made systems. Biological systems can use this climbing capability to protect themselves from ground-based enemies or to obtain an advantageous position for surveillance. Human-made systems find similar advantages particularly if one of their core functions is gathering intelligence, surveillance or reconnaissance (ISR). Climbing vertical surfaces is a difficult task as evidenced by the relatively few mechanical systems that have climbing capabilities. Biological systems use a wide variety of methods to climb. In this work, we show how a mind map, which displays numerous ways that biological systems climb, can be used to develop concepts and prototypes for mechanical systems that climb. In particular, a mind map that contains 11 different examples of how biological systems climb is used in the concept generation or ideation step in a design process to produce numerous ideas for mechanical climbing systems. The mind map contains both pictorial and text information on the climbing capability for the biological entity. After use of the mind map for ideation, a “down-select” process was used on the set of concepts resulting in the selection of two concepts for prototyping and testing. One concept involved attaching a ladder-like structure to the wall and creating a robot with ladder climbing abilities. The second concept implemented a projectile that was launched and adhered to the wall. The projectile had an attached tether. A robot then used the tether to winch itself up the wall. The mind map was found to be effective in assisting the development of concepts for wall climbing capability and the resulting two prototypes showed definitive feasibility of the two wall climbing concepts.
