Anik is suffering from a fever. His medical condition is vulnerable. So, he casually got up from bed and ate a capsule full of nanorobots! 
Sounds impossible? Trust me, current research in biomedical robotics suggests that this ‘impossible’ phenomenon might come true. They give us hope that one day we will have nanorobot swarms to kill bacteria and viruses (even the ones that caused Anik's fever) inside our bodies. 

Biomedical nanorobots can cure acute diseases like cancer and tumors by destroying targeted cancer cells, leaving healthy cells alone and unharmed. In chemotherapy, nanorobots are used to improve the pharmacokinetics (activities of the drug) and reduce the systemic toxins of chemotherapy through selective targeting and delivery of this anticancer drug. We can also use nanorobots for monitoring a person's overall health, such as looking for weak signs of organ deterioration. Due to their small size, they could provide medicine to suitable areas and deliver vaccines to the body. 

Biomedical robots are also effective in helping disabled people out there. Bionic eyes are still in development. This eye is made of a digital camera (obviously, not installed in the eye socket yet.), an external processor, and a microchip which will be attached to the brain through stimulating electrodes. All these will be connected to a pair of glasses, and the wearer can see through the lens. DARPA, a military organization currently working on bionic limbs which will contain artificial nerve endings. It means that these artificial nerve clusters will allow the wearer to control the limb with their mind with direct sensory feedback.
Da Vinci robot! Unlike the famous artwork, this latest robot is widely popular for crucial medical surgeries. This robot gives the surgeon a magnified 360-degree view of the operative field. The surgeon can use the console's hand and foot to remotely move the robotic arm attached to the surgical instrument* Da Vinci XI is the newest form of the robot, which offers some great additional features that will create a revolution.
Regarding nanobots, researchers think that nanobots could simulate the structure of human bones or resin for dental systems and create graphene nanoribbons to repair spinal cord wound possibilities. They are looking into nanobots for DNA use to find specific gene sequencing. It can also identify bacteria or genetic alterations.
Also, Nanorobots can help us clean up the world, which we call environment remediation. Moreover, we could use it for purifying water. They could clean up contaminated groundwater. Nanobots have the possibility of a significant impact on modern society. We can have great benefits from it.

Humanoid robots have been designed to have a human-like appearance and are capable of performing tasks that typically require human-like movements and abilities. These robots are an exciting and rapidly advancing engineering and computer science field with many potential applications. Artificial intelligence is a critical technology that has enabled the development of humanoid robots. AI allows robots to become more intelligent and capable of performing complex tasks, such as recognizing objects, navigating environments, and interacting with humans.
Another significant development for humanoid robots is computer vision. It allows robots to perceive their environment and make decisions based on what they see. For example, a computer-aided humanoid robot could navigate a crowded room without bumping into people or objects.
Now, let's see the recent trends in humanoid robotics. We all recognize Sophia, a humanoid robot created by the Hong Kong-based company Hanson Robotics. She has made many public appearances, including on TV shows and at conferences, where she has demonstrated her ability to converse and interact with humans. 
Another impressive humanoid robot is Atlas, developed by the engineers at Boston Dynamics. Atlas can perform various acrobatic maneuvers, such as backflips and cartwheels. It can also navigate rough terrain and climb stairs, making it one of the most advanced humanoid robots in the world.

Autonomous robots are intelligent machines that can independently complete tasks in the real world and work for extended periods except with human intervention. These robots usually have advanced options which will facilitate them to grasp their physical setting and automatize components of their maintenance and direction that want to be done by human hands. Most of these robots are designed to make life easier and more fun for humans. 
Examples of autonomous robots include "Autonomous Medical Delivery Robots." These Robots move freely around a physical space without being physically guided by humans. Scientists designed these robots to navigate busy hospitals and health systems and work alongside people. These autonomous robots navigate hallways and elevators round the clock, carrying medications, laboratory samples, and vital alternative things – boosting potency and output while not breaking a sweat. It can deliver items quickly, safely, and reliably, improving staff experience and patient outcomes while increasing productivity.
