What are Microbots? Well, as the name suggests, in layman’s terms, these are ‘tiny’ robots that perform a variety of functions. Several movies like Innerspace revolve around this concept that may become a reality in the future.
Microbots can perform a wide variety of functions, from replacing surgeons in healthcare to revolutionizing the education sector, you name it!
You are not wrong if you call this fiction, for this concept is not yet actuality and intrigues scientists and technologists. However, with the ongoing development in the field of artificial intelligence, robotics, and mechanics, this could actually come true!
A nanorobot is a robot that is created on the nanoscale, and a microbot is just a bit larger than that, which gives you an approximate idea of how tiny it is! However, don’t let its size fool you, for it can perform the most complex tasks with sheer professionalism and accuracy.
Owing to their tiny size, Microbots can be put inside the human body and used in diagnostics and medicine. A fact that may astound you, but researchers created a robotic cockroach utilizing Microrobotics! The HAMR or Harvard’s Ambulatory Microrobot (HAMR), is a Microrobot that resembles a cockroach and moves at a whooping speed of 19 inches per second!
On a similar note, RoboBee created by Harvard imitates a bee and can also swim! It flew for the first time in 2013 and in 2015, its swimming ability was engineered!
With these developments, it is certain that Microrobotics as a field has immense scope.
Microrobotics is a term that refers to small-scale robotics. These robots are often used for research purposes or the industry of biotechnology. These often measure less than one millimetre, even smaller than the length of a human hair strand! However, the size isn’t fixed and can vary depending on the purpose and components being used.
These tiny, yet extremely powerful robots have been used for a variety of purposes like healthcare, education, research and environmental science. These ‘technological creatures’ can cross any terrain with ease and cross unexplored remote environments from deep sea trenches to deserts.
These bots represent the future of technology and pave the way for advancements in science. With this groundbreaking invention, every domain of the world can be touched, and associating the word ‘impossible’ with science may become a thing of the past.
The field of robotics is extremely promising and every passing day is bringing a plethora of opportunities in this field. This is the dawn of the Microrobotics Era that is all set to transform our lives!
2. Design and Manufacturing of Microbots
Since these machines are extremely tiny, their designing and manufacturing process is arduous and sophisticated. The designing of these robots starts with the identification of the task to be solved. For instance, if the robot is to be put inside the human body for diagnostics, it will have to be extremely tiny and immune to bodily fluids.
Be it medical procedures, environmental monitoring, or industrial inspections, the overall shape and design are dictated by the purpose. Software called Computer-Aided Design (CAD) is utilized to make precise three-dimensional models considering the component information, efficiency, and functionality. To cite an example, medical robots should be designed in a way so that they can navigate through the human body without difficulties.
The design and manufacturing process of these teeny-tiny yet power-packed robots requires a convergence of expertise in various fields like robotics, material science, microelectronics, and bioengineering. These Microbots should also possess remarkable electrical capabilities and are hence made using advanced materials like piezoelectric substances, smart polymers, and memory alloys.
Locomotion is also a considerable aspect because scientists and researchers have attempted to develop Microbots with cilia, flagella, and micro-scale legs to propel them forward.
3. Applications of Microbots
Microbots are a groundbreaking advancement with a multitude of applications spanning different domains. These tiny yet mighty machines add utility to the fields of industrial growth, medicine, healthcare, and environmental monitoring. All of the problems that Microbots can solve were previously considered unsolvable.
For instance, these little marvels of science can deliver drugs inside the human body without off-site risks and can also aid in the diagnosis of various diseases. Since they can access the areas of the body that are hard to reach, they can aid in curing diseases like cancer.
Microbots are also bringing a wave of revolution in environmental monitoring and medication. They can monitor the concentration levels of different pollutants in water bodies, soil, and air and can also help clean contaminated areas or localities.
They can also prove to be of great help in inspection activities, especially in factories or industries. They can replace human labor and increase the efficiency of work to be performed.
4. Microrobots in Medicine
The most significant and noteworthy application of Microbots in the field of medicine is ‘precise drug delivery’. Conventional drug delivery systems have their share of side effects, the biggest one being their effect on healthy cells.
These methodologies pose a risk of affecting the non-diseased properly functioning parts of the body along with the diseased parts. However, these Microbots can be engineered to function like tiny ‘hands’ that ensure the proper delivery of medicines. This level of treatment not only improves effectiveness but also patient outcomes.
Microrobots can also aid in in vivo diagnostics. Basically, these tiny machines spanning a few millimetres can be built with sensors that can detect various diseases in the tissues and organs of the human body. They can also be used to provide endoscopy treatments by analyzing and examining the gastrointestinal tract.
Moreover, there are many intricate surgeries that can be easily and safely performed with the help of Microbots. There are regions of the human body that are inaccessible to human hands, therefore surgeons can remotely control these machines to operate on such areas with the risks being significantly reduced.
As we make continuous efforts to widen the reach of artificial intelligence and machine learning in the domain of medicine, Microrobots hold the promise of transforming healthcare. Microrobots are set to pave the way for a healthier future.
5. Cons of Microbots
Although Microbots have a multitude of advantages to bring to the table, they also possess their fair share of demerits just like every other technological innovation.
One major issue that has come forward is the unethical and immoral usage of these tiny machines. For instance, these can be a threat to privacy protection as there is potential for misuse. Since these Microbots are becoming ubiquitous, they can possibly be utilized for monitoring or recording purposes without the acknowledgment or consent of the people. This is a case of unauthorised data collection which requires vigilant actions.
There is always a risk that because of their small size, they can also be used for notorious or malicious activities like burglary, privacy breaching, and trespassing among others.
Additionally, as these robots become useful in almost all areas of the world, this may cause unemployment as jobs are displaced. This may cause an economic disturbance and disruption of balance in the global market.
Furthermore, there is a risk of weaponization and misuse of microbots by individuals or organizations with malicious intent. As with any technology, the potential for harm exists, and addressing these security threats would be of paramount importance to prevent disastrous scenarios.
So, though Microbots have opened a gateway of opportunities and possibilities, their demerits cannot be given a wide berth. By taking all these problems into consideration, like ethics, privacy, safety and environmental monitoring, we can ensure the safe usage of these portable technological marvels.
The rise of Microbots is a symbol of the age of technology and artificial intelligence with the potential to be the catalyst for revolution for different industries and address serious challenges. As engineers toil from dawn to dusk to meet the engineering requirements of these ‘miniature miracles‘, the opportunities look endless.
From accurate medical procedures to environmental monitoring, these robots have found their way to help in almost everything.
6.2. Ethical Considerations
As we continue to probe forward into the world of Microbots, it is extremely important that we ensure responsible utilization of the advantages that these robots have to offer. Humanity is all about keeping the ethical implications in mind.
