On summer 2012, the E-Lab in Purdue University has developed a very interesting object searching algorithm for TurtleBot: https://engineering.purdue.edu/elab/blog/research/synthetic-vision/robotics-and-vision/

I follow their setup notes and come to here: https://github.com/e-lab

Unfortunately it seems that the turtlebot codes and online learner have been removed from github.

Therefore, I would like to ask, does anyone know where to find their search demo codes?

Thank you very much indeed.
