The Georgia Robotics and Intelligent Systems (GRITS) Lab conducts research in the general area of networked and hybrid control systems, with applications to the control and coordination of mobile robots. The common theme behind our different research threads is that we provide theoretically sound solutions to practically motivated problems.

Research at the GRITS Lab is organized in three main areas:

Hybrid Systems

A hybrid system is a dynamical system whose evolution contains both a continuous and a discrete component. Examples of such systems include switched systems, hybrid automata, and language-driven systems. Our research in this area focuses on optimal control, observers and observability, and specification languages for hybrid systems. Although this research is mainly of a theoretical nature, the application domains include behavior-based robotics, reactive and embedded systems, and biologically inspired control systems.

Networked Control Systems

A networked system is one comprised of a number of locally defined systems, held together by an information-exchange topology. Examples of such systems include sensor networks and multi-agent swarms. Our research studies how to produce systems with provable global properties from local interaction and communication rules. We are also investigating how such systems can be programmed and controlled using tools from such different fields as boundary value control and epidemic programming.

Mobile Robotics

We have developed a number of experimental testbeds and are conducting research on mobile robots and both structured indoor and unstructured outdoor environments. Topics under consideration at the GRITS Lab include how to make robots learn appropriate controllers as they navigate through complex environments, low-complexity path-planning, field robotics, and how to effectively structure and specify complex control and mission-level tasks for single as well as teams of mobile ground robots.

The GRITS Lab was founded by Professor Magnus Egerstedt in 2001, is located on the fourth floor of the Technology Square Research Building, and is a unit in the School of Electrical and Computer Engineering at the Georgia Institute of Technology. Its sponsors include the US National Science Foundation, the US Army Research Office, DARPA, NASA, and Rockwell Collins.
