(20) If you’ve got a quadruped robot, or a robot with wheels, it’s not really designed for that environment, so it might be able to adapt.
Quadrupedal
Definition:
(a.) Having four feet; of or pertaining to a quadruped.
Example Sentences:
(1) Both the segmental distribution of hindlimb dorsal root fibers and their pattern of termination in Clark's nucleus in the tree shrew were similar to that reported in quadrupedal primates and other quadrupedal mammalian forms.
(2) The opposite was observed in adult dogs, where bipedalism was shown to be much more energy-consuming than quadrupedalism.
(3) Specifically, for the same direction of platform movement, during bipedal stance muscles on one side of the lower limb were activated in a distal to proximal sequence; during quadrupedal stance, muscles on the opposite side of the lower limb were activated and in a proximal to distal sequence.
(4) Human children, at the transitional stage between quadrupedalism and bipedalism, have high and almost equal requirements for all postures and locomotions.
(5) The vastus lateralis muscle is of primary importance in leaping inasmuch as it initiates the jumps; on the contrary the activity of the vastus intermedius does not increase during jumping, but it is the only one to be active in quadrupedal resting postures.
(6) Interlimb co-ordination typical of swimming (or trotting) in adult quadrupedal vertebrates was already present on postnatal day 1, and so apparently the neural pattern generating circuitry for this behaviour is already established by this stage.
(7) Compared with resting posture, the principal findings are 1) cardiac output shows a minimal increase for humans in bipedal stance and a noticeable increase for dogs as well as humans in quadrupedal stance; 2) quadrupedal stance in humans and dogs and bipedal stance in dogs require increased blood supply to the muscles of the neck, back, and limbs, while human bipedal stance requires none of these; 3) cerebral blood flow (internal carotid) in humans did not change as a result of bipedal posture or locomotion, but showed a noticeable drop in quadrupedal posture and an even further drop in quadrupedal locomotion.
(8) Tail-arm suspension is practiced more rapidly on thinner supports, and on more negatively inclined supports than is quadrupedal movement.
