The researchers found that bipedal desert rodents move with highly unpredictable trajectories, while sympatric quadrupedal
desert rodents move in much more predictable trajectories.
In a jointly authored paper, "Rapid Pole Climbing with a Quadrupedal
Robot," they explain the workings and capabilities of RiSE Version 3, a prototype dynamic four-legged robot that can quickly scamper over uneven terrain, but more importantly, rapidly ascend a vertical structure.
small mammals, joints are immobilized in a neutral standing angle to optimize limb function and to minimize adverse effects on ipsilateral and contralateral joints.

Avaliaram-se, no piquete, o posicionamento do animal, se em posicao quadrupedal
ou decubito, o periodo de alimentacao, a frequencia de ingestao de agua, ruminacao e ocio.
The design and control of a jointed-leg type of a quadrupedal
robot for locomotion on irregular ground.
This phenomenon was suggested by Pinkham (1977) to explain the limb correlation relationships observed in the quadrupedal
Mexican spiny pocket mouse (Liomys irroratus) a form that closely resembles the ancestral, fossil form of all the Heteromyidae, and its bipedal relative, the kangaroo rat (Dipodomys merriami).
In clinical practice, we are familiar with the consequences of a trade-off between our supposed quadrupedal
past and (relatively) recently acquired bipedality.
The species of rat that lives beneath New York City like a gang of quadrupedal
straphangers is the Norwegian rat, or Rattus norvegicus.

AND BIPEDAL MAMMALS.
