The Cave Crawler mining robot
Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world? It’s an increasingly urgent question,given the recent high-profile(引人注目的)mining accidents in Sago, W. Va., and Huntington, Utah. A small group of engineers and robotics experts envision(展望)a day in the not-too-distant future when robots and other technology do most of the dangerous mining work..
One of the first mining robots was developed five years ago at Carnegie-Mellon University’s Robotics Institute. It was called Groundhog and it looked like a golf cart. It used lasers to “see” in dark tunnels and map abandoned mines—some of the most dangerous work in the business.
The latest prototype is called Cave Crawler. It’s a bit smaller than Groundhog, and even more advanced. It can take photos and video and has sensors mounted that can detect the presence of dangerous gases. Incredibly, the robot has a real sense of logic. If it comes across an obstacle it gets momentarily confused, it has to think through the process and where to go next, and sometimes it throws a fit just like a real person.
