Robots are versatile machines, evidenced by their wide variety of forms and functions. Here's a list of a few kinds of robots we see today:

Healthcare:

Robots in the healthcare industry do everything from assisting in surgery to physical therapy to help people walk to moving through hospitals and delivering essential supplies such as meds or linens. Healthcare robots have even contributed to the ongoing fight against the pandemic, filling and sealing testing swabs and producing respirators.

You need look no further than a Roomba to find a robot in someone's house. But they do more now than vacuuming floors; home-based robots can mow lawns or augment tools like Alexa.

The field of manufacturing was the first to adopt robots, such as the automobile assembly line machines we previously mentioned. Industrial robots handle a various tasks like arc welding, material handling, steel cutting, and food packaging.

Everybody wants their online orders delivered on time, if not sooner. So companies employ robots to stack warehouse shelves, retrieve goods, and even conduct short-range deliveries.

Mars explorers such as Sojourner and Perseverance are robots. The Hubble telescope is classified as a robot, as are deep space probes like Voyager and Cassini.

Robots handle dangerous tasks, and it doesn't get any more difficult than modern warfare. Consequently, the military enjoys a diverse selection of robots equipped to address many of the riskier jobs associated with war. For example, there's the Centaur, an explosive detection/disposal robot that looks for mines and IEDs, the MUTT, which follows soldiers around and totes their gear, and SAFFiR, which fights fires that break out on naval vessels.

We already have toy robots, robot statues, and robot restaurants. As robots become more sophisticated, expect their entertainment value to rise accordingly.

Travel:

We only need to say three words: self-driving vehicles.

Advantages and Disadvantages of Robots

Like any innovation today, robots have their plusses and negatives. Here’s a breakdown of the good and bad about robots and the future of robotics.

They work in hazardous environments: Why risk human lives when you can send a robot in to do the job? Consider how preferable it is to have a robot fighting a fire or working on a nuclear reactor core.

They’re cost-effective: Robots don’t take sick days or coffee breaks, nor need perks like life insurance, paid time off, or healthcare offerings like dental and vision.

They increase productivity: Robots are wired to perform repetitive tasks ad infinitum; the human brain is not. Industries use robots to accomplish the tedious, redundant work, freeing employees to tackle more challenging tasks and even learn new skills.

They offer better quality assurance: Vigilance decrement is a lapse in concentration that hits workers who repeatedly perform the same functions. As the human’s concentration level drops, the likelihood of errors, poor results, or even accidents increases. Robots perform repetitive tasks flawlessly without having their performance slip due to boredom.

They incur deep startup costs: Robot implementation is an investment risk, and it costs a lot. Although most manufacturers eventually see a recoup of their investment over the long run, it's expensive in the short term. However, this is a common obstacle in new technological implementation, like setting up a wireless network or performing cloud migration.

They might take away jobs: Yes, some people have been replaced by robots in certain situations, like assembly lines, for instance. Whenever the business sector incorporates game-changing technology, some jobs become casualties. However, this disadvantage might be overstated because robot implementation typically creates a greater demand for people to support the technology, which brings up the final disadvantage.

They require companies to hire skilled support staff: This drawback is good news for potential employees, but bad news for thrifty-minded companies. Robots require programmers, operators, and repair personnel. While job seekers may rejoice, the prospect of having to recruit professionals (and pay professional-level salaries!) may serve as an impediment to implementing robots.
