Research Projects

The laboratory conducts an aggressive research program centered on the design and control of advanced robotic systems. Since 1999, this work has been supported by more than $3,000,000 of research funding. Students participate in these projects through a variety of programs that include graduate student thesis work, the School of Engineering's Senior Design Project program, a special research workshop in telerobotics, internship programs, course activities, and/or externally sponsored projects.  

New Opportunities

Several research opportunities are currently available in the lab.  These are capable of supporting studies at both the Capstone and Thesis level:

  • Model-based system operations for both anomaly management and command planning/execution
  • Multi-robot formation control and collaborative manipulation
  • Spacecraft subsystem development
  • Internet-based robotic control with time-varying delay
  • Comparative manipulator endpoint control (speed/position control vs joint/endpoint/camera space)

Primary Research Areas

Model-based Control of Robotic Systems - This work focuses on the use of fundamental design information to compute operational conjectures regarding the monitoring and control of complex robotic systems.  A key element of this work includes new theoretical contributions to the Theory of Model-Based Anomaly Management; this work has include conceptual development, algorithm composition and implementation via Matlab, and experimental application on several satellite flight proejcts.

Cluster space Control of Multi-Robot Systems - This work focuses on the cluster space paradigm (developed by RSL) to specify and control flexible multi-robot formation geometries suitable for collaborative applications  A set of formal kinematics is used to relate cluster space variables to individual robot variables.  To date, this work has included experimental demonstrations of both automated trajectory control and interactive piloting, the use of potential-field-based collision avoidance, and application to both holonomic and non-holonomic vehicles.
