This design limits the locomotion of the system and it does not allow controlled propulsion nor locomotion in open areas since the only propulsion force forwards comes from pushing the tendril from its base, where the system is flexible and lacks actuation.
During the same time period, the injured animals injected only with matrigel had limited joint locomotion (Figure 6C).
While the hind limbs were capable of bearing the weight of the body on land, the proportions of the limbs and the long phalanges of both hands and feet would have limited terrestrial locomotion and prevented Maiacetus from traveling any substantial distance from water.
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.
Thus, one might expect cells to adhere very firmly to any substrate and to one another, even without any specific adhesion molecules, potentially limiting or preventing locomotion.
This impairment in locomotion could limit the feeding capacities of pups and could potentially worsen the size deficit already observed at birth.
Only the front two legs were wired for the purposes of this experiment, which limited the types of locomotion available, but the researchers note that two-legged gaits do occur naturally in hexapod creatures.
"You have an amazing ability to reproduce human emotion in VR, and limited ability to do locomotion without making the viewer sick," said Tim Sweeney, who leads Epic Games.
e.g. mutants have limited capacity for producing locomotion and expend most of it on x-axis movement of the paw since it's critical for task performance, whereas other aspects of behavior are allowed to vary?
Since these pigs have been bred for life in small indoor pens in which the area for movement and good locomotion is limited, their ability to cope in a more diverse environment may have diminished, and problems with lameness may potentially arise.
