Millions of years of evolution have already solved difficult design problems in locomotion, manipulation, sensing and navigation in almost every environment in which a robot might conceivably need to operate.
The completeness of the fossil allows us to reconstruct aspects of life history, diet, and locomotion that are difficult to study in fossils.
It is more difficult to recognize the abnormal locomotion in B. okinawaensis than in C. elegans.
The results suggest that cross-slope walking requires functional musculoskeletal adaptations that may be difficult for animals with impaired locomotion.
This suggests that differentiating sound from very mildly lame sheep is more difficult, but once sheep are locomotion score 2 or above (defined in Table 2) the majority of participants recognise lame sheep.
Many researchers have used springs and dampers in series with motors to protect the robot from forceful impacts during locomotion, but it's difficult to control a spring's stiffness and damping ratio — which can be a problem if a robot has to traverse disparate surfaces, such as asphalt and sand.
In very large herds however, cows with locomotion problems are more difficult to spot and the herdsmen may also be more likely to cull lame cows.
However, continuation of appropriate exercises in a home setting is difficult, and few reports are available on locomotion training in a home setting.
It's an ideal environment for testing Valkyrie's on-board vision systems and bipedal locomotion, setting up cramped and difficult-to-navigate surfaces to mimic the capsule and space walks some future generation robot will hopefully encounter one day.
However, the anxiolytic-like effects of buspirone at doses of 10 and 30 mg/kg were also accompanied by effects on locomotion, making interpretation of the data difficult, and suggesting that the effects of the 10 and 30 mg/kg doses of buspirone on the anxiolytic measures may be due to sedation, rather than anxiolysis (see Cole and Rodgers 1994).
These species, however, do not consolidate wake into a single, daily bout and manipulations of locomotion elicit changes in wakefulness, making it difficult to parse the relative contribution of these two factors.
