Redundancy in Robot Manipulators and Multi-Robot Systems

The trend in the evolution of robotic systems is that the number of degrees of freedom increases. This is visible both in robot manipulator design and in the shift of focus from single to multi—robot systems. Following the principles of evolution in nature, one may infer that adding degrees of freedom to robot systems design is beneficial. However, since nature did not select snake—like bodies for all creatures, it is reasonable to expect the presence of a certain selection pressure on the ...
