Robotic innovations like Rail-Veyor's conveyor system for hauling materials in and out of mines are taking some of the human factor out of mining, making it more efficient and safe for workers. (Source: Rail-Veyor Technologies)
It isn't only the safety issue that drives the need for robotics in the mining industry. I used to work in the industry for a number of years and another disadvantage is that the minerals are in the middle of nowhere. (Actually, you fly into the middle of nowhere and then drive another 100 miles). The personnel costs are astronomical because the miners have to be located at the site and their families are elsewhere. In some instances, even infrastructure (such as water systems) need to be brought out to the mine, so the less people actually there, significant reduce the costs.
Researchers have been developing a number of nano- and micro-scale technologies that can be used for implantable medical technology for the treatment of disease, diagnostics, prevention, and other health-related applications.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
