A robot has successfully mapped down to the bottom of the world's deepest sinkhole. Or at least, the investigators think so.|
The sinkhole may be connected to even deeper caverns. At the bottom of the slope, was an area DEPTHX's could not probe. This could be simply a depression or the entrance to further caves. The researchers hope to send the probe back later this week to find out, and to explore any connected passages.Because there's no map, the robot uses a self-mapping guidance system called SLAM.
