 As the name implies, sliders move themselves across the
         ground by selectively sliding body parts along. So far,
         sliders come in 3 sub-categories:
 
            
               | Snakes | Propel themselves via a horizontal wave
                  motion |  
               | Earthworms | Propel themselves via a compressive longitudinal
                  wave motion |  
               | Miscellaneous | Odd, non-biologically-inspired robots |  |
