Driving unit design and motion analysis for a spiral propulsion mechanism in wetlands

Environmental problems related to wetlands have attracted strong concern around the world during past decades. Mobile mechanisms of many kinds have been developed to satisfy demands of environmental investigation of wetlands. However, few researchers have studied spiral propulsion mechanisms. Our pr...
