Robotics is an engineering discipline focused on designing and manufacturing of robots. This area of engineering is related to computer science, mechatronics, artificial intelligence, and bioengineering. Science-fiction writer Isaac Asimov is widely considered the first man to use the term “robotics.” He also was the author of its three main principles, or Three Laws of Robotics:

Robots shouldn’t harm humans.

Robots should follow the given instructions without violating the first rule.

Robots should protect themselves without violating two other rules.

Robots have many applications, performing various tasks which are usually performed by humans. They build cars in assembly lines, disarm explosive devices, explore the bottom of the ocean and space. You can also buy a robot cleaner which will move around your home and clean the floor. The robotics industry evolves all the time, and engineers constantly discover new ways robots can help us solve various problems.

Today, many people realize how important it is to learn robotics. Knowledge of robotics not only can give you an interesting profession but also can help you develop and improve various skills. For example, when learning robotics, you can also learn creative thinking, concentration, programming, teamwork, and get more prepared for the future of technology in general.

Main Trends of the Robotics Industry

First, industrial robots, including mobile robotic platforms and articulated manipulators, become cheaper. The commercial sector is excited about new applications of robots, and the agricultural sector may become the most promising market for robots in the nearest future. Drones and UAVs have already proven to be effective for such tasks as fertilizing, carrying heavy items, and monitoring livestock.

The commercial sector expresses its excitement by increasing investments in this industry. Google and Amazon buy robotics companies. Moreover, Amazon has turned one of such companies, Kiva Systems, into Amazon Robotics. The new company is focused on automation, machine learning, computer vision, language perception, and other issues which are very important for the future of robotics. Toyota has invested $50 million in collaboration with Stanford and MIT to develop new solutions for self-driving cars, and other companies from this sector also don’t lag behind. Even venture capitalists, who used to be cautious about investing in this industry, are actively funding robot startups.

Another trend in robotics is cloud technologies. Clouds allow robots to exchange and process large amounts of data in real time. Cloud robotics may solve one of the biggest problems in the industry — the lack of computing power. Clouds can expand the computing capabilities of machines significantly, enabling them to perform tasks that had seemed to be impossible before. The latest developments in the field of big data may also be used by the robotics community to cope with the information collected by robots which have multiple sensors.

Many robots can collect data on social media. Artificial intelligence and machine learning can help robots use data from social media to improve their perception capabilities and to better understand the world we’re living in.
