For nearly a century, pop culture has paved the way for society to express itself in fantastical ways. The very word “robotics” conjures up images of robot house servants, droids from Star Wars, and other fanciful forms of robotic friends or foes.
However, the field of robotics itself is a fantastic meld of computer science, artificial intelligence (AI), machine learning (ML), and software engineering.
But how far along are we as a society to implement robots from science fiction? Well, it may not be like the movies, but robotics is an awe-inspiring and nuanced field of study that, if science-minded, you should definitely consider exploring.
What Is Robotics?
Robotics itself is both simple and complex. Overall, it refers to the development and implementation of robots. However, robotics involves a staggeringly large amount of disciplines under its banner.
In the United States, most car manufacturers take advantage of robotic precision to meet deadlines and quotas. At the same time, developments continue to advance in self-driving cars. You could realistically have a scenario where a robot manufactures an automobile, and AI drives the vehicle right off the assembly line.
But what’s the endgame with robotics? The overall goal is to design intelligent, thinking machines in numerous ways. This is where advances in technologies like AI have been so significant for robotics.
What Is Robotics Used for?
Robotics technology has a ton of uses, from human operators attempting to create simple machines that act on their own accord to industrial robots that assist in the manufacturing of products.
- Assisting humans in day to day activities. This is probably the most important and widespread use of robots in the real world. Designers and software engineers collaborate to create functioning machines to help humans in several ways. This can be in the assembly line at factories or even in the form of a self-driving car. The ability to assist humans and make life easier has always been an extremely prevalent end goal for many robotic endeavors.
- Performing dangerous tasks. The benefit of having a competent robot at your disposal is that it can withstand trauma, extreme temperatures, and more. This leads to the efforts of things like robots who dismantle and detect explosives like IEDs, perform maintenance work in underwater environments, and generally perform tasks where humans couldn’t realistically survive.
Types of Robots
Robots come in all shapes and sizes. Let’s explore some of the most common robotic systems we encounter in the real world today.
Human-like Robots
These types of robots gain the most press coverage. Due to their uncanny resemblance to humans, these types of robots enchant and sometimes bemuse the general public. Software developers and engineers pour thousands of hours into creating robots that walk, talk, and generally attempt to act human.
Human Augmentation Robots
While prosthetics assist those who have lost limbs to accommodate the real world better, augmentations go a step further. A prosthetic leg acts as a facsimile of a leg in appearance and shape. An augmentation aims to stimulate the core components of the legs.
This means realistic movement, performance, and precision. These great additions to the field of robotics can be a fantastic opportunity for individuals who have experienced an injury and loss.
Human Operated Robots
While there are some autonomous robots, these specific types of robots operate only under the guidance of a human operator. Human operated robots are perfect for the tasks mentioned above and duties like defusing bombs, fixing things in dangerous areas, and helping clean things like oil spills.
Autonomous Robots
Autonomous robots work on their own. These machines have more advanced AI, like ML, to act of their own accord. Have you ever seen a Roomba? These tiny robots move around the room, vacuuming all on their own. While not the super-advanced robot butler, these autonomous machines can operate independently of human operators.
Collaborative Robots
Known as “COBOTS,” these unique robots work alongside humans in a designated space. Collaborative robots aim to assist humans in specific industrial work with clearly defined boundaries. For example, a collaborative robot and a human can share the same room, but never the same working space.
This is great for something like an assembly line, as it combines human thinking with mechanical precision. Collaborative robots are extremely sensitive to the human’s reaction and can respond to a human’s action quickly. For collaborative robots, it’s all about coexistence with humans.
Learning Robotics
Now that you know a little more about the field of robotics, what next steps do you take if you want to learn what it takes to develop and build robots?
Let’s take a closer look at how long it takes to create a robotics application, how to learn the fundamentals in a few steps, and some resources for further learning.
How Long Does It Take to Learn Robotics?
A general consensus on this question is about five years. Of course, this depends on many variables. Robotics isn’t something you can pick up by reading internet posts. You can glean important info from web pages and other resources, as you’ll soon see below, but robotics takes time and energy.
How long you will take to learn depends on education level and dedication to computer science, AI, and deep learning.
How to Learn Robotics: Step-by-step
Below are a few key steps to learning robotics.
- Familiarize yourself with the fundamentals of robotics. If you want any hope of building the next Boston Dynamics full-functioning robot, you are going to need a reliable well of knowledge to draw from. Books, resources, and courses will help you learn all you need to know to start a career dealing with robotics.
- Take robotics classes. The benefit of nearly everything being online now is that you can find various courses. This goes for robotics, too. You will see online courses for things like artificial intelligence, computer science, and machine learning that will instill within you a great toolset to work with.
- Get robotics certifications. You can earn certificates in several fields that can assist you in the field of robotics. For example, you can earn a certification in software engineering and AI. Certificates can be an attractive feature to a resume or portfolio.
- Experiment with robotics. Robotics, along with being a discipline that includes many calculations, math, and data, also emphasizes building robots. There are resources to try your hand at building your own robots. Experimentation with physical robotics, along with computer science and AI, is a great way to get a better idea of what you’re dealing with.
- Pursue a degree and apply for jobs. One of the best ways to enhance existing robotics knowledge is to earn a degree in robotics or a related field. This gives you the prerequisites to apply to different high-ranking jobs at places like software companies.
