SUBTERRANEAN CHALLENGE AT DARPA

Hey everybody,

I wanted to share some very cool tutorials about the DARPA SubT Challenge and a dataset.

These hello world tutorials for the DARPA SubT Virtual Testbed will walk you through the complete process of developing the software stack for a simulated robot (SLAM, Robot Perception, Navigation and Communication). Thrilling.

Several tutorials:

Also an awesome dataset about the same topic:
https://github.com/ShreyasSkandanS/pst900_thermal_rgb

PST900, a dataset of 894 synchronized and calibrated RGB and Thermal image pairs with per pixel human annotations across four distinct classes from the DARPA Subterranean Challenge.

The directory structure for this dataset is as follows:
