I recently completed my PhD in the SHAPE Lab at Stanford University, where my advisor is Professor Sean Follmer. My research focuses on shape changing robotics and flexible mechanisms, which we are currently using to create dynamic, smooth tangible user interfaces and shape changing robots. I was funded by the NSF Graduate Research Fellowship Program, the Stanford Graduate Fellowship, and the Stanford Leadership in Teaching Fellowship.

Many robots, such as those found in manufacturing facilities, are designed for well-defined environments where the conditions of operation are known in advance. However, for many tasks it is necessary that a robot can adapt to its surroundings. We use the inherent shape change ability of flexible loops to make a shape-changing, crawling robot that is capable of steering and handling multiple terrains.

Shape displays are a type of tangible user interface that can generate multiple physical forms in a reconfigurable manner. In this work we detail the design and actuation of flexible rod shape displays – a novel type of tangible user interface. The smoothness, high compliance, and easy manipulability of flexible rods make them a promising medium for expressing high curvature shapes – a task with which many existing shape displays struggle.

This project is a work in progress. It extends the curved line display into a surface display by combining curved line segments in a grid.

In this work, we present a multi-stable curved line shape display, with which we are able to display high curvature, smooth shapes by bending the ends of a flexible rod. We used a discrete elastic rods simulation to inform our actuation strategy, and demonstrated the display's ability to display a variety of shapes consistent with simulation results.

More and more, we all interact with data-driven graphs to understand our environments and current events. However, information that is conveyed only visually is inaccessible to blind and visually impaired users. Some alternatives exist, but they are often non-refreshable or prohibitively expensive. We attempt to address this through a 1-DOF haptic device.
