For instance, an autonomous amphibious vehicle which can travel on aquatic and terrestrial terrains by using four driven paddle wheels was presented by Frejek et al. [27].
Roaming this strange, extra-terrestrial terrain, they get lost in the maze of shelves where Riley's memories are stored, they visit the sound stage where her dreams are performed, they bump into her long-neglected imaginary friend, and they take a ride onher Train of Thought.
Low mass compact rovers provide cost effective means to explore extra-terrestrial terrains.
ePaddle mechanism is a novel hybrid locomotive mechanism designed for accessing terrestrial, aquatic and amphibious terrains with versatile locomotion gaits.
Siliceous hot-spring deposits, or sinters, typically form in active, terrestrial (on land), volcanic terrains where magmatically heated waters circulating through the shallow crust emerge at the Earth's surface as silica-charged geothermal fluids.
To guarantee its mobility, the locomotion mechanism of the robot should be able to adapt to diverse terrestrial, aquatic, and amphibious terrains.
However, limited by their locomotion ability, above amphibious robots still cannot be applied for search and rescue tasks after tsunami, where multiple gaits on terrestrial, aquatic, and amphibious terrains are required.
In order to obtain useful data on the tractive performance of the ExoMars rover before flight, it is necessary to perform mobility tests on representative soil simulant materials producing a Martian terrain analogue under terrestrial laboratory conditions.
Characteristics of occupied sites were described by Knorr (1961) and included five requirements: presence of water, which also allows moss to grow for use in nest building; high relief, or a commanding position above the surrounding terrain; inaccessibility to terrestrial predators; darkness or shading of nest niches; and unobstructed flyways for approaching the nest.
This behavior can arise, for example, in underwater acoustic communication channels or in terrestrial communication channels over hilly terrain.
By contrast, we know surprisingly little about how terrestrial animals move so well in natural terrain, and even the best robots still struggle in complex terrain such as earthquake rubble, cluttered buildings, forest floor, and Martian rocks, an ability required for important applications like search and rescue, structural examination, environmental monitoring, and planetary exploration.
