Project 2Project 2. Frog biorobotics (‘Frobotics’).
How does differential use of limb joints affect swimming performance?
We will build a frog-inspired swimming robot powered by independently controlled joint actuators at the hip, knee and ankle. Using torque transducers at each joint we will record joint work and power required to move the feet for producing thrust. Data from the robot will help verify mathematical models relating limb and foot kinematics to hydrodynamic performance. We will also gain novel insights into the differential roles of joints (and their underlying musculature) during swimming. Furthermore, the robot will help determine how different limb kinematics patterns may be used to control the transmission of power from actuators to the water during propulsion.
