Efficient 3D Visual Perception for Robotic Rock Breaking
2019 IEEE 15th International Conference on Automation Science and Engineering (CASE), 2019 In recent years, underground mining automation (e.g., the heavy-duty robots carrying rock breaker tools for secondary breaking) has drawn substantial interest. This breaking process is needed only when over-sized rocks threaten to jam the mine material flow.
