Healthcare:Robotics technology is being used to assist surgeons in performing complex procedures and to help patients with physical therapy and rehabilitation. Additionally, robotic technology improves surgical precision, stability, and dexterity. Some of the applications of robots in medical surgery are:
- Robots employ magnetic resonance and computed tomography image data to direct devices to the treatment location during image-guided operations.
- The use of remotely operated robots during minimally invasive operations allows the surgeon to operate within the patient's body without creating significant incisions.
- Brain lesions can be biopsied by image-guided robots in neurosurgery with little collateral tissue injury.
- In orthopedic surgery, robots are commonly employed to accurately form the femur for prosthetic hip replacements.
Additionally, robotic devices are being developed for closed-chest heart bypass, microsurgical ophthalmology operations, and surgical training and simulation (Howe & Matsuoka, 1999).
- Transportation: Self-driving cars and drones are examples of robots being used in transportation.
- Agriculture: Robotics technology is being used to plant, cultivate, and harvest crops.
- Space exploration: Robots are used to explore space and to collect data on other planets and moons.
- Search and rescue: Robots are used to search for survivors in disaster-stricken areas, such as earthquakes or floods.
- Entertainment: Robotics technology is being used to create lifelike animatronics for theme parks and movies.
- Service industry: Robots are increasingly being used in customer service roles, such as hotel front desk receptionists or customer service representatives. Further, some companies such as Starship and Kiwibot, have deployed hundreds of food-delivery robots on college campuses and city streets in the United States and the United Kingdom.

What are robots?
Robots are machines that can perform tasks autonomously or with minimal human supervision. They can be programmed to perform a wide range of functions, from simple repetitive tasks to complex and sophisticated operations. Robots are typically controlled by a computer or microcontroller, which receives input from sensors and sends commands to the robot's actuators (motors, servos, etc.) to control its movement and actions. Robots can be classified into different categories based on their design, function, or application, such as:
- Industrial robots: These are robots that are used in manufacturing, assembly, and other industrial processes. They are typically large and stationary and are used for tasks such as welding, painting, and material handling.
- Service robots: These are robots that are designed to interact with humans and perform tasks such as vacuuming, cleaning, or providing customer service.
- Mobile robots: These are robots that can move around, such as self-driving cars, drones, or robots used for search and rescue.
- Collaborative robots (cobots): These are robots that are designed to work alongside humans and can be programmed to perform specific tasks.
- Humanoid robots: These are robots that are designed to resemble humans, either in appearance or functionality. They are used in a variety of applications, such as entertainment, research, and education.
- Medical robots : These are robots that are used in medical industry to perform surgeries or other medical procedures with high precision and accuracy. The benefits of robotic surgery include shorter hospital stays, lower rates of complication as well as the ability to execute finer tasks than traditional laparoscopic and open procedures. (Hussain et al., 2014)
All these robots are controlled by a computer program which gives them instructions on what to do and how to do it.
Navigation in robotics
Navigation is the process of determining the position and movement of an object or a vehicle in a given environment. In robotics, navigation refers to the ability of a robot to move around and navigate through its environment. This includes the ability to sense and interpret the environment, determine the robot's location and orientation, and plan and execute a path to a desired destination.
There are several types of navigation techniques used in robotics, including:
- Dead Reckoning: This is a navigation technique that uses sensor data and mathematical calculations to determine the robot's location and orientation. It is based on the idea that if you know the robot's starting position and the distance and direction it has traveled, you can calculate its current position.
- Simultaneous Localization and Mapping (SLAM): This is a navigation technique that uses sensor data and mathematical algorithms to create a map of the robot's environment and to determine its location within that map.
- Global Positioning System (GPS): This is a navigation technique that uses satellite signals to determine the robot's location.
- Visual odometry: This is a navigation technique that uses visual sensors, such as cameras, to track the robot's movement and determine its location.
- Obstacle avoidance: This is a navigation technique that uses sensor data to detect obstacles in the robot's environment and plan a path around them.
- Path Planning: This is a navigation technique that uses mathematical algorithms to plan a path for the robot to reach a desired destination.
Overall, Navigation is a critical aspect of robotics, as it enables robots to move around and interact with their environment safely and efficiently.
Drones, also known as unmanned aerial vehicles (UAVs), are aircraft that can fly autonomously or with minimal human supervision. They are typically controlled by a computer program or a remote control, which gives them instructions on where to fly and what to do. Drones come in a variety of sizes and shapes, and can be classified into different categories based on their design, function, or application. Some examples include:

- Fixed-wing drones: These drones have a winged design, similar to that of an airplane, which allows them to fly longer distances and at higher speeds.
- Multi-rotor drones: These drones have multiple rotors that allow them to hover in place and make precise movements, making them ideal for tasks such as aerial photography and videography, as well as search and rescue operations.
All these drones are equipped with various sensors, cameras, and other technologies that allow them to gather information and communicate with the ground control. They can fly at high altitudes and travel long distances, providing a unique perspective and making them useful for a wide range of applications.
Overall, the digital age has brought about many changes to contemporary society, and it continues to shape the way we live, work, and communicate. The integration of robotics and AI in the digital age has led to the creation of new forms of technology that are having a significant impact on society.
