"Fish robotics: using mechanical devices to understand the functional and evolutionary diversity of fishes"
George V. Lauder
Henry Bryant Bigelow Professor
Professor of Organismic and Evolutionary Biology

SMAST East Rooms 101/102
836 S. Rodney French Blvd, New Bedford
Abstract
There are over 35,000 species of fishes, and a key feature of this remarkable evolutionary diversity is the variety of propulsive systems used by
fishes for swimming in the aquatic environment. Fishes have numerous control surfaces which act to transfer momentum to the surrounding fluid.
In this presentation I will discuss the results of recent experimental kinematic and hydrodynamic studies of fish locomotor function, and the implications
for construction of robotic models of fishes. Recent high-resolution video analyses of fish fin movements during locomotion show that fins undergo much
greater deformations than previously suspected and fish fins possess a clever active surface control mechanism. Experimental analyses of propulsion in
freely-swimming fishes have led to the development of a variety of self-propelling robotic models including, most recently a tuna-like robot. Data from these
devices will be presented and discussed in terms of the utility of using robotic models for understanding fish locomotor dynamics, and for studying the function
of specialized fish surface structures like shark skin.

Brief Biography
George V. Lauder received the A.B. and Ph.D. degrees in biology from Harvard University in 1976 and 1979 respectively, and from 1979 to 1981 he
was a Junior Fellow in the Society of Fellows. Since 1999 he has been Professor of Organismic and Evolutionary Biology at Harvard University. His research
interests focus on the biomechanics and evolution of fishes, and applying our understanding of fish locomotor function to the design of fish-like robotic devices.
