In coal production, the raw coal contains a large amount of gangue, which affects the quality of coal and pollutes the environment. Separating coal and gangue can improve coal quality, save energy, and reduce consumption and make rational use of resources. The separated gangue can also be reused. Robots with computer vision technology have become current research hotspots due to simple ...

View object in our online collection. First, a little background history. Canaries were used in mines from the late 1800s to detect gases, such as carbon monoxide. The gas is deadly to humans and canaries alike in large quantities, but canaries are much more sensitive to small amounts of the gas, and so will react more quickly than humans.
