The future of robotics: How will robots change the world? Part 2

Jun 01, 2021

Types of robots

Although the concept of robots has existed for many years, it’s only been in the last few decades that they’ve grown in complexity and use. Nowadays, there are many practical applications for robots across a wide range of fields.

As discussed in our open step on the applications of robots, some of these types of robots include:

  • Industrial. Perhaps the most common use of robots is for simple and repetitive industrial tasks. Examples include assembly line processes, picking and packing, welding, and similar functions. They offer reliability, accuracy, and speed.
  • Military. More recent developments mean that military forces worldwide use robots in areas such as UAVs (Unmanned Aerial Vehicle), UGVs (Unmanned Ground Vehicle), triage and surveillance.
  • Service. One of the main growth areas in robotics is in the personal service industry. Uses include for manual tasks such as dispensing food and cleaning.
  • Exploration. We often use robots to reach hostile or otherwise inaccessible areas. A good example of exploratory robots is in space exploration, such as the Curiosity Rover on Mars.
  • Hazardous environments. Again, certain environments can be dangerous for humans to enter, such as disaster areas, places with high radiation, and extreme environments.
  • Medical. In the world of healthcare, medtech robots are being used in all kinds of ways. Whether it’s managing laboratory specimens or assisting with surgery, rehabilitation, or physiotherapy.
  • Entertainment. Increasingly (particularly during the pandemic), people are buying robots for enjoyment. There are several popular toy robots, and there are even robot restaurants and giant robot statues.

 

Advantages and disadvantages of robots

The field of robotics offers solutions to many different problems. As we’ll see, the future of robots could change the world we live in. However, that doesn’t mean there aren’t downsides to the technology.

As explored on our open step from the University of Reading, there are various pros and cons of using robots in our modern world:

Advantages of robots

  • They can offer increased productivity, efficiency, quality and consistency in certain settings.
  • Unlike humans, robots don’t get bored.
  • Until they wear out, they can repeat the same process continuously.
  • They can be very accurate, even to fractions of an inch, making them particularly useful in the manufacturing of microelectronics.
  • Robots can work in environments that are unsafe for humans, such as with dangerous chemicals or in areas of high radiation.
  • They don’t have physical or environmental needs in the same way humans do.
  • Some robots have sensors and actuators which are more capable than humans.

Disadvantages of robots

  • In some industries, robots are replacing human jobs, which can create economic problems.
  • On the whole, robots can only do what they are told to do, meaning they can’t improvise (although AI and machine learning is changing this).
  • Current robotics technology means that most machines are less dexterous than humans and can’t compete with a human’s ability to understand what they can see. Although experts are working on developing robots that can better sense the world.
  • Robots with practical applications are generally expensive in terms of the initial cost, maintenance, the need for extra components and the need to be programmed to do the task.

 

The future of robotics: Will robots take over the world?

Robots are already all around us, whether it’s the automated machines that assemble our vehicles or the virtual assistants that use conversational interfaces to help us around the house. Yet as we’ve seen, they’re not currently suitable for all areas of life. But will that change in the future?

Despite fears of an AI takeover, where machines replace humans as the dominant intelligence on the planet, such a scenario seems unlikely. However, business network PwC predicts that up to 30% of jobs could be automated by robots by the mid-2030s.

Other reports suggest that the stock of robots worldwide could reach 20 million by 2030, with automated workers taking up to 51 million jobs in the next 10 years. So, while they may not take over the world, we can expect to see more robots in our daily lives.

 

How robots will change the world

According to a report from McKinsey, automation and machines will see a shift in the way we work. They predict that across Europe, workers may need different skills to find work. Their model shows that activities that require mainly physical and manual skills will decline by 18% by 2030, while those requiring basic cognitive skills will decline by 28%.

Workers will need technological skills, and there will be an even greater need for those with expertise in STEM. Similarly, many roles will require socioemotional skills, particularly in roles where robots aren’t good substitutes, such as caregiving and teaching.

We may also see robots as a more integral part of our daily routine. In our homes, many simple tasks such as cooking and cleaning may be totally automated. Similarly, with robots that can use computer vision and natural language processing, we may see machines that can interact with the world more, such as self-driving cars and digital assistants.

Robotics may also shape the future of medicine. Surgical robots can perform extremely precise operations, and with advances in AI, could eventually carry out surgeries independently.

The ability for machines and robots to learn could give them an even more diverse range of applications. Future robots that can adapt to their surroundings, master new processes, and alter their behaviour would be suited to more complex and dynamic tasks.

Ultimately, robots have the potential to enhance our lives. As well as shouldering the burden of physically demanding or repetitive tasks, they may be able to improve healthcare, make transport more efficient, and give us more freedom to pursue creative endeavours.

 

How to get started with robotics

If you’re an aspiring roboticist, there are several ways you can get started in the industry. You’ll need to work on some key skills, such as mathematicsscience, programming, and problem-solving. You’ll also need to understand the basics of robotics and get some practical experience programming and building them.

With our course Robotics with Raspberry Pi, you can learn how to connect motors, add sensors and write algorithms to build your very own robot buggy. You could also develop expertise in a field such as deep learning to master areas of AI and machine learning.

You can also learn about some of the key areas within robotics, such as the use of robotics in healthcare and how we can build a future with robots.
