BadgerWorks

High-risk, High-reward Research for Undergraduates

What is BadgerWorks? The goal of “BadgerWorks: High-risk Research for Undergraduates” is to develop an undergraduate student-organization for ground-breaking robotics and AI research, an organization tailored to undertaking great challenges and moon-shot projects. BadgerWorks aims to be the place for highly-motivated students to build their skill, the environment in which the most difficult but also most rewarding problems are attempted to be solved. As such, BadgerWorks can have significant impact in the excellence of our University and offers outstanding educational, research and career building experiences.

What is BadgerWorks working on? BadgerWorks is organized around thematic long-term moonshot-like projects. Currently, the BadgerWorks activities are organized around two correlated research themes:

Subterranean Robotics. Can we make robots able to operate autonomously in the underground environment? Can they enter cave networks, explore and map them? Can we develop small robots capable of opening (boring) tunnels and creating complex underground networks much like many animals do? What innovations in vehicle design, sensing, control, planning and reinforcement learning techniques are required? The goal is to assemble a multi-disciplinary team of 5 undergraduates to conduct fundamental research in relation to these problems. Two core milestones are considered, namely that of navigation in cluttered underground cave-type environments and b) the ability of drilling a hole of a size such that the robot can burry itself underground.

SpaceBadgers. This project aims to develop a new generation of space robotics for underground mining operations with the goal to enable autonomous extraction of minerals from asteroids of the inner solar system. Such robotic systems can have tremendous impact in the effort to enable the extraction of resources to fuel the industry and sustain life in space. In particular, this project aims to develop prototype technologies for ultra-lightweight robots that are simultaneously able to localize and navigate autonomously in the extreme underground space environments, while being able to extract minerals from self-developed mine drifts and headings. A field evaluation plan is planned to take place in environments that are sensing- and terrain-wise analogous to asteroids and specifically at the Mojave Desert.

Indicative design related to Subterranean robotics. Such leg-wheel robots can enable agile locomotion at low-cost.

How do we work at BadgerWorks? In principle BadgerWorks emphasizes on the self-organization and knowledge development among students. For that purpose students are encouraged to organize their own lectures, coding workshops, hackathons and other such activities for collaborative knowledge development and sharing of know-how. However, further to this basic direction, students in BadgerWorks are supervised by members of the Autonomous Robots Lab both at the individual and at the team level. In addition, a series of activities are organized by the lab in relation to BadgerWorks including specialized seminars, lab presentations, workshops to explain key robotic methods and software and more.

What resources do we have available? BadgerWorks is hosted at the facilities of the Autonomous Robots Lab at the Applied Research Facility (ARF) building. Members of BadgerWorks have access to a) the Autonomous Robots Arena for comprehensive robot testing and evaluation, and b) the robot development equipment of our lab. You have the benefit of being assigned a dedicated space and the ability to access and use world-class research infrastructure.

How do I get involved? Please send an e-mail at kalexis@unr.edu. Some of us will meet and discuss with you to get you immediately involved!

Can I combine it with my studies? Yes! Directed and independent studies perfectly fit the scope of work and vision of BadgerWorks. Contact kalexis@unr.edu to arrange accordingly.
