Multi Agent/Object Simulation in Human Swimming

Fish-Inspired Swimming Simulation and Robotic Implementation

This paper describes our efforts to develop a Digital Fish Simulator (DFS), particularly aiming at creating a controlled kinematic centered environment to further shed light on how to design and control artificial fish robots. Compared to a 3D simulator for autonomous robotic fish by Liu and Hu, an improved body wave equation capable of multimodal swimming motions is adopted in our simulator an...

Fast simulation of animal locomotion: lamprey swimming

Abstract. Biologically realistic computer simulation of vertebrate locomotion is an interesting and challenging problem with applications in computer graphics and robotics. One current approach simulates a relatively simple vertebrate, the lamprey, using recurrent neural networks for the spine and a physical model for the body. The model is realized as a system of di↵erential equations. The dra...

The optimum finger spacing in human swimming.

Competitive swimmers spread fingers during the propulsive stroke. Due to the inherent inefficiency of human swimming, the question is: does this strategy enhance performance or is it just a more comfortable hand posture? Here we show, through computational fluid dynamics (CFD) of a 3D model of the hand, that an optimal finger spacing (12 degrees , roughly corresponding to the resting hand postu...

Human sperm cells swimming in micro-channels

The migratory abilities of motile human spermatozoa in vivo are essential for natural fertility, but it remains a mystery what properties distinguish the tens of cells which find an egg from the millions of cells ejaculated. To reach the site of fertilization, sperm must traverse narrow and convoluted channels, filled with viscous fluids. To elucidate individual and group behaviors that may occ...
