The Future Of Mining

Future of mining and mining robots. What will they look like

With driverless trucks, the Internet of Things, and automation creating a safer and more futuristic industry, AMSJ chats to QUT Professor of Robotics Jonathan Roberts about the future of mining industry and the impact of automation and robotics on mining.

Tell me about your background, and how you got into the robotics industry?
I did a Bachelors degree in Aerospace Systems and then went on to do a PhD in the area of self-driving cars. I focussed on robotic vision systems for the cars and I naturally went into robotics research after that. I moved from the United Kingdom straight after my PhD and joined CSIRO as they were beginning their research in the area of mining robotics. Our first major project at CSIRO was to show how a dragline could be automated.

What is the future of robotics in mining?

The future of robotics in mining is very bright. Mining is an ideal industry for robotics as the use of robotics can help improve safety while at the same time improving productivity.

The key developments involve driverless vehicles and, in particular, robotic vehicles that are capable of safely working around people or people driving in standard mining vehicles.

The technologies to make this happen include the use of radar and robotic vision systems, along with tracking systems and universal wifi across the mine site

Should companies be embracing new technologies? The stigma with automation is that people will lose jobs, as one of the immediate negatives but what are some of the positives, particularly when it comes safety, productivity and costs?

Robotics and automation have many benefits, and improvements in safety is what interests us the most. However, there are other less obvious potential benefits of developing robotic mines. The most significant is the fact that mines may be able to stay open longer if they are highly automated.

A great example is that of deep underground mines. As mines go deeper, they become less economic – it is simply more expensive to get the ore out of the mine.

There is also a large expense associated with providing ventilation for miners deep underground. If you can use robots for many of the mining tasks, the mine may have lower running costs, hence meaning a mine may stay economic longer – thus maintaining all the associated support jobs that relate to that mine. So, in some cases, a robotic mine may result in more jobs and not less.

When starting a new concept or idea do you start with a need on site or do you start with the function of a robot and adapt it to be of benefit?


The normal process starts with a problem at a mine site that the mining company thinks a robotic technology might be able to address. Researchers then see how existing technology might be applied to the problem and also if any new technology is could be conceivably developed to tackle the mine’s problem. It is common to adapt technology developed for other applications. The driverless car is a good example in that much of the technology developed for these vehicles has been applied to driverless haul trucks.

Do you find that when a concept isn’t working it is completely discarded, or more often than not the idea is simply re-purposed and used later?

Often the technology works but there are other reasons that it is not adopted. It may be that there are no companies with the skills to commercialise the robot. It may be that the number of robots required are not large enough to make it economic for a company to build them.

Sometimes the researchers are simply ahead of need but the fact that they have demonstrated a solution colours the mine’s future plans and they build the next mine in a way to support the use of that robot.

There are common misconceptions that a robot can walk, talk and think, which is not true. But, what is your definition of a robot?

For me a robot is an autonomous machine that either moves itself or has an arm that moves.

Is that definition changing when it comes to Artificial Intelligence (AI) and advances in technology?


Yes, we are finding that new robots are now responding to the world. Old factory based robots were far more automatic and less autonomous. Modern robots, and robots in mines, need to respond to the environment around them. Advanced sensing combined with Artificial Intelligence is what makes this possible.

What are three biggest future changes in technology that will impact the advances of robotics? Is there a potential future for AI in mining?


The mass production of technology, such as the smartphone, will allow all the humans on a mine to interact with the robots in a far safer and simpler ways thanks been possible until now. The coming driverless car technology will mean that all mine vehicles can be made to drive autonomously. A mine site is actually far simpler than our public road network. Advances in AI, in particular the area of machine learning, will inevitably result in far smarter robots that improve their performance over time.

Will a robot, or automation ever fully replace a human being on a mine site? Will a robot ever be able to fix and maintain a robot?
Current robots have not been designed to be maintained by other robots. The current driverless haul trucks are based on standard trucks that again have not been designed to be maintained by robots. It is only when robots and vehicles are specifically designed to be maintained by other robots that we may see far fewer humans on a mine site. For now, many of the humans on a mine site will still be required for maintenance.

What are you working on at the moment?
At the moment, myself and my colleagues are working within the Australian Centre for Robotic Vision. Our aim is to give robots the gift of sight. Until robots can see, we are unlikely to see them used widely. The development of reliable seeing robots will enable robots in a wide range of industries including manufacturing, medicine and health care, building and construction, and of course mining.

And finally, what are the three laws of ‘mining’ robotics (from Asimov’s laws of robotics)?
I am not really a fan of Asimov’s laws of robotics. Way too simplistic for me.
