Multi-Robot Coverage and Resource Allocation

Following my work in collaborative teleoperation, I’ve been working on a coverage control approach to multi-resource allocation. We use a coverage control policy to deploy a team of mobile robots tasked with supplying resources of varying quantities and types to areas of demand.

Collaborative Teleoperation

During my first year in the Collaborative Autonomy Group, I worked on enabling “co-navigation” of ground robots, in which a human teleoperates a ground robot, such as a powered wheelchair, through an environment, while the robot provides navigational assistance to the human via haptic feedback.

Haptic Modules

During my first lab rotation in graduate school I worked with students in the BU Robotics Lab to develop five haptic modules (shown on the left), with different types of haptic feedback. Our goal is for these modules to be a tool to rapidly develop prototypes of tactile displays.

Medical Robotics

In 2019 I was a research fellow at Stanford University, where I primarily worked on developing an MRI-compatible surgical teleoperation device. I also developed a mold for phantom tissue for experiments.

Haptic Feedback

In 2018, I developed a haptic skin-stretch device for prosthetic limbs at George Mason University. In 2019, before I worked at Stanford, I also worked on quantifying task completion abilities for user studies.

Snake Biomechanics

I studied flying snake biomechanics from 2017 to 2020 at Virginia Tech. I analyzed data and also had the opportunity to travel to Australia’s Daintree Rainforest to study a close relative of the flying snake.
