Welcome to the lab of Dr. Joshua Vaughan in the Department of Mechanical Engineering at the University of Louisiana at Lafayette. Our research includes a variety of controls and robotics related work, including vibration control, input shaping, crane control, human-machine interfaces, mobile robotics, mine detection, and inspection robots.
Yes, we're following a long line of labs doing great work that have acronym names, such as the GRITS Lab at Georgia Tech and the GRASP Lab at the University of Pennsylvania. In our case, we're paying homage to a delicious creature from our Louisiana home, the crawfish. For us, C.R.A.W.LAB is the home to research focusing on Controls, Robotics, and Automation, With respect for human interaction.
We aim to make C.R.A.W.LAB inclusive and respectful to all. For more information, see the C.R.A.W.LAB Code of Conduct page on this site.
