Christopher Thierauf

Hello, World!

My name is Chris Thierauf.

I'm a robotics research assistant and PhD student at the Human-Robot Interaction Lab at Tufts University. I design, build, and program robots that help investigate how people and robots interact in human environments.
On this website, you can find more about my publications, other past projects, check out my curriculum vitae, or get in touch.

Graduate Research

My graduate level research began in September 2020. Two papers are currently pending peer review. Research that has passed peer review is available below.

Curriculum learning on simulated and real-world robots (published in AAMAS).
Demonstrated technique for complex multi-step problem solving by enabling a robot to learn through auto-generated curriculums.
You can read the paper here
Yash Shukla, Christopher Thierauf, Ramtin Hosseini, Jivko Sinapov. “ACuTE: Automatic Curriculum Transfer from Simple to Complex Environments”, AAMAS 2022.

UVC Disinfection Robot (published in ICRA).
Paper on creating a robot and an algorithm to provide formal disinfection guarantees for UVC-light based robots at a substantially reduced cost point.

Undergraduate Research

Lecture on 3D printing and Free Software at LibrePlanet, Spring 2019.
A talk I gave on 3D printing and its growth alongside the Free software/hardware environment, as well as how 3D printing can be used to further software/hardware freedom in various industries.
You can watch the full presentation here.
Christopher Thierauf, "Free Software in the 3D Printing Community", LibrePlanet, MIT, 2019.
Undergraduate conference paper on networking 3D printers, Summer 2018.
I created and wrote a paper on a tool called "printfarmer", which enabled networking 3d printers together for automated print farms.

Christopher Thierauf, "Networking 3D Printers with Printfarmer", IEEE MIT Undergraduate Research Symposium, 2018.
Laser Scarecrow grant involvement, Summer 2018.
I helped to create a device called a "Laser Scarecrow", which uses lasers to emulate movement to scare birds away from crops. The grant issued focused on creating one of these systems for substantially cheaper than existing systems. The grant issuer wrote an article on it you can read here
Northeast SARE FNE18-893, "Laser Scarecrow Prototype"

Other projects and robots

I write code, including these ROS packages:

gpio_control
Package and python utilities to control GPIO on Linux SoC's (Raspberry Pi, NVidia Jetson, etc).
Available as a ROS package and via
apt-get.
discretized_movement
Simplify the MoveIt action space through cartesian discretization for reinforcement learning applications.
Available as a ROS package.
pybullet_simplified_fetch
Simplified physics simulation environment for the Fetch robot mobile manipulator.
Available as a ROS package.
rosactive
When working with several independent ROS projects simultaneously, managing the different workspaces and shell variables can be difficult. rosactive is a CLI utility to resolve this.
Available as a ROS package.

I also build stuff:

Sledbot
An autonomous, low-cost mobile robot capable of being configured to carry a variety of loads. My contributions were to perform the electrical design, core control software, and wheel assembly.
Plugbot
A small robot initially designed to work with the Sledbot for the purpose of seeking out charging sources. Later adapted to become a more extensible low-cost platform by combining 360-degree LIDAR, IMU, wheel odometry, and cameras.

Undergraduate Level

Underwater ROV (Undergraduate IEEE Chapter project)
I wrote the control code for 3 teleoperated underwater robots over the course of 4 years, half of which I served as the software project lead. I also worked on sensor interfaces and networking setups to create unique cohesive systems.
"Enbarr" (Bs.C Capstone project)
Mechanical, electrical, and software design for an extensible underwater research platform. A laser-cut metal plate produces the structure while silicone covers all components for waterproofing.
Laser Scarecrow
Funded by Northeast SARE FNE18-893 to repel birds from using lasers, which are non-harmful to crops and animals. The system brought crop loss down by 85 percent at an order of magnitude cheaper than existing solutions while meeting grant requirements.
Spectral Digitizer
Project goal was to create a machine to digitize physical records of elemental spectra per request of NIST. I wrote code to control stepper motor at high precision at the direction of experienced engineers.
