Post hoc comparison (Bonferroni) was performed when significance was found. It has been demonstrated at the DARPA Robotics Challenge. C. All primates everywhere are endangered today. The projections intersect in 2048, when the quadrupedal 100-m sprint world record will be lower, at 9.276s, than the bipedal world record of 9.383s. Although gallop has been widely considered to be a gait, transverse and rotary gallops can be distinguished. More generally, investigation of quadrupedal running will not only result in the development of new techniques that allow biomechanists to study locomotion in natural settings but will also reveal the underlying principles of how these runners accomplish their astonishing performances; this may also result in the development of novel actuation materials that are lightweight, robust, compliant, and easy to manufacture into various designs. (2004), we used the SE equation to calculate the 95% confidence intervals for the predicted 100-m sprint world records as follows: where t is the world record time, y is the year, s is the sample SD, and n is the sample size.
