“…Consequently, bio-robots are not limited by energy shortage capabilities when traveling over long distances and are more skilled than electromechanical robots when conducting complex missions. As bio-robots are superior to electromechanical robots in many potential applications, researchers have been investigating different types of bio-robots, such as rats (Feng et al, 2007 ; Huai et al, 2009 ; Pi et al, 2010 ; Zhang et al, 2012 ; Su et al, 2014 ; Zheng et al, 2015 ; Yu et al, 2016 ), geckos (Guo et al, 2009 ), sharks (Gomes et al, 2006 ), goldfishes (Kobayashi et al, 2009 ), carps (Peng et al, 2011 ), cockroaches (Holzer and Shimoyama, 1997 ), pigeons (Su et al, 2012 ), beetles (Hirotaka et al, 2008 ), and honeybees (Bao et al, 2011 ).…”
