Hannah will start as an Assistant Professor at the University of California Berkeley in January 2018.
I focus primarily on improving the dexterity of highly under-actuated fingers and hands, with a special interest in marine applications. More information at: Underwater Manipulation
Marine manipulation: Ocean One hands and suction flow
My primary motivation has been the submersible humanoid Ocean One, a robot intended to bring intuitive telepresence to delicate marine environments. The adaptive, multifinger, tendon-driven Ocean One Hands are controlled from a haptic console. They can perform both precision pinches and strong wrap grasps with a single actuator. My thesis includes (1) task-specific finger and transmission design for controllable grasp force distribution, (2) evaluation of performance intended to guide teleoperator control of the hands, and (3) field testing during Ocean One’s maiden mission to the La Lune shipwreck. I am also exploring the addition of gentle suction flow to the fingertips as a way to enhance and sense contact, especially with light and slippery objects underwater. I have implemented dynamic simulations to efficiently analyze grasp performance and understand complex parametric design trends. These are validated with experimental methods and multi-material mechanism prototyping using a mix of 3D printing and conventional fabrication techniques.
