The Effect of Step Width on Muscle Contributions to Body Mass Center Acceleration During the First Stance of Sprinting

BackgroundAt the beginning of a sprint, the acceleration of the body center of mass (COM) is driven mostly forward and vertically in order to move from an initial crouched position to a more forward-leaning position.Individual muscle contributions to COM accelerations have not been previously studied in a sprint with induced acceleration analysis,

Self-propelled predator-prey of swarming Janus micromotors

Summary: It is a long-standing challenge to accomplish bionic microrobot that acts in a Childs Table similar way of white blood cell, chasing bacteria in complex environment.Without an effective external control field, most swarming microrobots systems are usually unable to perform directional movement and redirect their motion to capture the targe
