Brett Browning

I'm a Senior Systems Scientist in the Robotics Institute at Carnegie Mellon University. I'm affiliated with the National Robotics Engineering Center, or NREC for short. Additionally, I have a split assignment with the Computer Science Department at Carnegie Mellon's Qatar branch campus, where I co-direct the Qri8 robotics lab.

My main research interests focus on perception and autonomy, although I also have done lots of work in multirobot and human-robot teams particularly in the robot soccer domain. I am deeply interested in developing robots that have an impact on society. In particular, I am very interested in deploying robots to industrial settings where the need for robots to take on dirty, dull, and dangerous tasks can have a big impact on improving safety and productivity. I am particularly interested in bringing robots into the Oil and Gas industry and solving the perception and autonomy challenges faced by robots working in a difficult, semi-structured environment with or without human operators. I run projects at RI, NREC, and Carnegie Mellon Qatar that are attempting to address many of these issues.

Research

My recent publications are online. Please contact me if you have any questions or any papers are missing.

The following is a list of my current active projects.

Visual SLAM for Industrial Robots
We are exploring algorithms to support visual mapping and localization for a robot vehicle operating in an industrial setting such as an LNG production plant. This will be work with Joe Cheben, Tony Stentz, and Bernardine Dias. This work is sponsored by QNRF.
LNG Pipe Vision
We are developing a perception system to fit onto a pipe crawler. Our system will build 3D appearance models of the inside pipe surface and register changes in appearance and structure over time in order to support automated corrosion detection. This work is with Peter Rander and is sponsored by QNRF.
VANE
We are exploring a mix of physics-based and data driven high fidelity sensor modeling techniques. The goal is to develop a system that can provide much more realistic UGV simulation than current techniques. Such simulation will play a crucial role in speeding up the development cycle, and in validating platforms. This is work with Peter Rander and is sponsored by the US ACE ERDC.
Multi-cultural Human-Robot Interaction
We are exploring human robot interaction in a mixed cultural setting. To do this exploration we have developed a robot Hala that runs in the Carnegie Mellon Qatar central reception and speaks both English and Arabic. This is work with Majd Sakr and Reid Simmons and is sponsored by QNRF.

These are older projects that are either no longer active, or I am no longer directly involved with.


Learning by Demonstration with Advice
We explored a range of techniques to enable rapid acquisition of skills (ie. control policies) by a robot from a human teacher. This was work with Brenna Argall and Manuela Veloso.
Boeing Treasure Hunt
We developed a distributed coordination architecture to enable dynamically formed teams from a mixed team of humans and heterogeneous robots to perform tasks. Our approach is robot architecture agnostic. This was work with Bernardine Dias, Manuela Veloso, Tony Stentz and Alex Rudnicky and was sponsored by Boeing. Please see the project page for more information.
Human-Robot Soccer
This project used Segway RMP robots to play soccer both indoors and outside with human teammates. Research issues are single robot autonomy, localization, multi-object tracking, skill learning, robust vision, teamwork with pickup teams. This was work with Manuela Veloso and was sponsored by DARPA. See our publications, images, and movies for more information.
Small-Size Robot Soccer
We developed a small-size robot soccer team to explore multi-robot coordination in an adversarial environment. Research issues are team autonomy, opponent modelling, fast path planning and control, robust hardware, skill learning. This was work with Manuela Veloso and was sponsored by DARPA. Please see our code, publications, images, and movies for more information.
Teams of UAVs (ACO)
This program looked at developing coordination algorithms and real-time kinodynamically constrained path planning for a team of UAVs. This was work with Manuela Veloso and James Bruce and Rockwell Scientific.
Aiding Driver Safety
We developed probabilistic algorithms to predict intended driver route based on historical data using low quality GPS. Additionally, we developed an efficient algorithm to estimate road grade from low quality 3D GPS fixes. This was work with Reid Simmons that was sponsored by General Motors.
CAMEO
We developed a vision-based system to observe and infer the interactions at meetings. This was work with Manuela Veloso, Paul Rybski, Fernando Del Torre, and Takeo Kanade and was sponsored by DARPA.
UberSim
We developed a real-time simulation engine to enable rapid prototyping of robot control algorithms with a modest level of realistic dynamics. Our approach allowed for configurable hardware platforms. See ubersim for details. This was work with Manuela Veloso and was extended by Mike Bowling at the University of Alberta.
Biologically Plausible Spatial Navigation
My dissertation work focused on developing a vision-based robot navigation system that was inspired from biologically models of the rat hippocampus. This work was been continued at the University of Queensland as part of the RatSLAM project and they now have some very impressive results.
