13 SUMMARY
Design of biomechatronic systems is a complex process and as such, it
would achieve a greater degree of economic, technical, and aesthetic excel-
lence when cloaked by logic and rationality. The influential and compli-
mentary concepts of systematic design and systems approach to design
reflect general appreciation that complex problems are best tackled in a series
of defined steps. Such structuring is governed by the nature of design envi-
ronment and directed at obtaining an optimum solution in the face of
imposed limitations. The boundaries of a design problem are therefore dic-
tated by the disciplines involved and the associated constraints. In other
words, limitations are formed by two sets: (a) intradisciplinary constraints
and, (b) specific problem constraints. The combined limitations of these
two sets would adversely affect a biomechatronic designer and even refrain
