Robot Technology and it’s working principle
Any type of machine using sensors and programmed to move or perform a specific task is referred to as robot technology. It combines and integrates mechanical engineering, electrical engineering, computer science, and artificial intelligence to build intelligent robots who can do anything from just repeating some simple movements, up to planning large size decisions.
Components of Robot Technology Mechanics and Hardware:
Actuators — These power the motion, can be things like motors or hydraulics.
Sensors : They enable the robot to collect data regarding its environment like cameras for viewing, proximity sensors, looking at any object and also gyroscopes which maintain the balance.
Controllers – The brain of the robot where the hardware communicates with the software to call functions
Software and Control Systems:
For robots, they are usually programmed to follow specific set of instructions or do actions based on real time data.
AI (Artificial Intelligence): The use of AI with these advanced robots allows them to be programmed to learn from the environment and adjust their actions on the fly, and possibly make decisions without needing human input.
Motion Control: Means for commanding robots in a straightforward, efficient, and intrinsically safe manner to move stably and navigate their surroundings.
Types of Robots:
Industrial Robots: Used in manufacturing for welding, painting, assembly and material handling.
Hospitals, hotels and even homes are starting to not only be cleaned by robotic vacuum cleaners but also receive the aid of a small fleet of robots in tasks such as surgery. Service Robots
Autonomous Mobile Robots (AMRs) — AMRs are self-guided and able to move from point A to point B in an environment, like a self-driving car or warehouse robot.
From Wikipedia: Humanoid robots — Robots designed to resemble human and are usually used for research or as a public relations tool rather then as industrial automation.
Collaborative Robots (Robots) – These robots work with humans, helping to perform some unskilled and semi-skilled jobs in a safe and effective manner.
Applications:
Manufacturing – Robots are employed to enhance production efficiency, accuracy, and save on boring or unsafe human tasks.
Health: Robots-based medicine and surgery, patient care, and rehabilitation.
Discovery: Robots are employed in space discovery and deep-sea as well as other dangerous environments where humans can´t access.
Military – Recon drones, combat support robots, and autonomous logistic systems.
Personal robots and home assistants like robotic vacuum cleaners, smart speakers that rely on voice commands (NLP) for automation of tasks
The robot technology continues to expand, deploying more and more of the artificial intelligence (AI), machine learning, as well as other technologies that enabling robots creep on full autonomy and complete freedom for quick smart capabilities.
Robot Technology and its working principle
The robot technology operates to a different principles relating to the interaction of components in robots which allows them to act independently or semi-independently. Due to the agent connection with specifics, it makes sense to separate them, where one action is receiving observations from an environment and another process next steps. This is how robots work basically:
1. Environment (Perception)
Sensors: Robots collect data from the environment and their own internal states. Sensors give the robot crucial data of how to navigate and interact with the world around it.
Output: Cameras and LIDAR Visual Sensors for object detection, navigation, and scene understanding.
Proximity sensors — detecting objects nearby, like ultrasonic or infrared%%
Touch Sensors — They are used to give an idea of physical contact, so that robot can reproduce results using force ( by moving with the force) or use fingers in right way.
Position- And Motion-Sensors: Gyroscopes, accelerometers and encoders for movement control.
The physical phenomena-by way of example light, sound and temperature (to list a few)— are sensed by the sensors and then converted into electrical signals which are relayed to the robots processing unit for subsequent analysis.
2. Data Processing (Compute and Control)
This is basically the brain of the robot which can be a processing unit called controller. It reads the sensor data, translates this data to a form it can understand and uses programming/algorithms/AI (artificial intelligence) in-built into the robot to make decisions.
Microcontrollers and Processors — To compute the requisite commands, based on the current state that it is in and its eventual programmed goals.
Machine learning : Other robots use machine learning where AI algorithms run on the processing unit to make decisions, adapt to new data or change their behavior over time in response to performance feedback.
Path Planning and Decision Making: The bot determines the trajectories to follow while navigating a route from origin to the destination, avoiding known obstacles and making informed decisions.
Operation: The processing unit check the input data and compare it against the predefined models or decision rules or sometimes with tech already learned behavior patterns, then sends the actuator commands to their actions.
3. Actuating Movement (Action)
An actuator is what physical moves the physical actions of a robot. These actuators change electrical signal into mechanical motion and allow the robot to move, grip things, or impact its environment.
Motors: You can use this to rotate wheels, and arms or joints.
Hydraulic/Pneumatic Actuators: Several with significantly more force for lifting, and pushing mechanical systems.
• Servo Motors: These provide precision movement control and are frequently used in robotic arms or for small work.
Are comprised of a controller that sends an electrical signal to an actuator, which then converts the signal into mechanical energy, enabling the robot to move physically — for example, by picking something up, moving or carrying out some other interaction with its environment.
4. On the other hand, a closed-loop control is response-after-stimulus where we are more sensitive to feedback (both negative and positive) and does impact how we will adjust our behavior afterwards.
The robot would usually receive feedback on its actions after executing them. It allows the robot to adapt its behavior on the fly using this feedback, and this results in more efficient and accurate performance.
This is the feedback loops: sensors are in charge of monitoring what ,in fact, the robot did and signs out to the controller. So, for example, a robot arm would be able to use force sensors to change its grip strength depending if they were handling delicate objects or not.
The controller compares the result, which is one of these measurements with the desired output and adds corrections to minimise any error, thus maintaining precision.
What is it: Closed-loop control systems are control systems that work in a feedback loop, making corrections when necessary to ensure that their outputs behave as expected.
5. Programming and Learning (f)icky emotions are easy.
Robots perform planned action, but some new robots can adjust to performing new tasks or to new environments using machine learning.
To me: Programing — Robots are programmed to follow specific rules, instructions or algorithms for task execution.
How about machine learning: some robots can solve problems from their slowly-building repertoire of experiences that allow them to recognize patterns and adjust things to succeed. A consumer could teach a robotic vacuum cleaner the layout of a room and make it more efficient over time.
BASICS Principle: Depending on the intelligence and autonomy level of a robot, these can either have deterministic behavior (hard coded) or non-deterministic behavior (learned).
Practice Instance Example
Think of a Roomba from Roomba vacuum cleaner:
Monitoring: It relies on LIDAR sensors to quickly map out the room and object analysis.
Compute: The on-board processor generates a map of the environment, and determines an efficient cleaning plan
Moving: Wheels move the robot from one location to another and actuator motors are moving gears of cleaning mechanism like brushes required for vacuuming.
Response: Sensors are the eyes of robots, providing real-time feedback if either a new object is detected or some existing one changes; in this case the processor recalculates the path.
E.g Learning: The robot may learn how the room is laid out and hence alter its cleaning process to better fit where it has been successful in previous iterations.
Working Principle Summary
Perceive the environment with the help of sensors
Control or utilize AI algorithms to process data
Actionner: agir avec des actionneurs sur du déplacement ou de la manipulation.
The feedback allows a way of adjusting and eventually correcting actions leading to enhancing the overall performance over time.
Together this sensing, computation and action is what makes robots able to act solo in the real world without any guidance from humans (as long as instructed by them or they have learnt past data).

Robot technology is changing industries and the way we work and live, this transformation makes use of these benefits.
Issues With Robotics Technology
While robot technology provides a number of benefits, it also has its downsides and issues. Here I want to share several of the main disadvantages doing so:
1. High Initial Costs
High Costs of Implementation: Even if it is less expensive to maintain a robot than human employees, the initial cost of introducing robots into your system can be very high for smaller businesses. Costs including robotic equipment, software and installation for modifications to enable robots for the Project (MC) are treated as part of a major capital project within that category.
Maintenance & Repairs: The cost of keeping robots running can be high, they will eventually break down and special technicians or even factory support is required.
2. Job Loss and Unemployment
Workers Displacement: Robots (as repetitive or manual tasks takers) replace human workers leading to unemployment especially in manufacturing and logistics services.
Skill Mismatch — Because robots are taking over routine tasks, job displacement may require new (increasingly higher-level) skills in order for workers to remain employed which leads to a skills gap between available jobs and skill levels of the public.
SOCIAL IMPACT: On a broader level, the international reliance on automation will create economic divisions as displaced workers from robots could lose their roles or even get trapped struggling to find work in different companies and/or industries.
3. Human flexibility and creativity were missing
Robots cannot adapt: Lastly, robots (especially if they are not AI-powered) do not have the versatility or ingenuity of human employees. These robots are rather limited to pre-programmed tasks and often have difficulties with complex or unforeseen situations that require human thinking or creativity.
Problem-solving limitations: Robots can solve problems but they are not as intuitive as humans, especially in the case of trouble-shooting or unexpected problems where emotional intelligence is required making a decision dynamically or some form of abstract reasoning is necessary.
4. Dependence on Technology
Over-dependence: The world of business would be left susceptible to failure when robots fail in a few specific cases. For instance, if one of the robots which could be a critical machine goes down, it might bring the whole production line to a stop until that issue is resolved.
System Malfunctions: Robots are machines after all, and just like humans they can experience system malfunctions in their software or mechanical assembly leading to production downtime, accidents or immediate product quality compromise.
5. Security and Privacy Risks
Potential Cybersecurity Threats: Robots, especially connected to the internet or networked environments are at risk of hacking and cyber-attacks there may be issues with protecting the integrity of data, operations, and personal privacy.
Concerns with Data Privacy: Home, hospital or customer service robots can collect highly sensitive personal data which raises the issue of privacy unless this data is securely managed.
6. Lack of Decision support
Lack of Emotional Intelligence: Robots do not possess the ability to feel emotions, know cultural context or special individual information from people speaking to them which makes it impossible for robots to execute tasks that need empathy, negotiation or human interaction.
Robots cannot ethically judge: Robots do not have the ability to make ethical judgements in complex situations, even if they are programmed with AI technology. In healthcare, law enforcement or military application this can be very dangerous.
7. Environmental Impact
Energy Usage: Robots, especially industrious ones, can take allot of energy. This raises the carbon emissions and is damaging to environment, if the energy come from dirty sources.
Electronic Waste (E-Waste): The end of life and mass obsolescence of robots can be a source of environmental concern. Those components may include toxic materials that need to be dealt with by a specialized recycling process.
8. Advanced Programming and Customization
Programming Challenges Developing and customizing robots to perform designated tasks can be complex, demanding expert knowledge in the fields of robotics, software development, and AI.
As good as AI-powered robots are becoming, they still can not understand context, natural languages or all the nuances of human behavior and so there are some tasks that we posibly could perform but these robots will not be able to do.
Adaption related: If your environment has quickly changing tasks/conditions, robots have to be reprogrammed/re-configured with it, which can ring up additional costs and time consumption.
9. Ethical and Moral Issues
Military Applications: On the other side of the argument, some critics have pointed out that many applications which improve efficiency by virtue of automation (e.g. factories) also displace human workers in favour of robots, creating a non-trivial ethical and social concern about job displacement.
Robot Warfare – Using robots and AI in the military arena, where lives are at stake without any human directed intervention raises moral objections. Concept such as an autonomous drone or a combat robot falls under this category.
Human-Robot Interaction: The level of human emotional empathy, care and friendliness in some tasks (e.g., healthcare or customer service) might be reduced when people over rely on robots.
10. Complexity of Integration
They have a high cost (because the parts are special), and they are also difficult to integrate into existing systems, whether these are manufacturing lines or software environments, for redundancy or they raise compatibility issues.
Training — Human workers need to be trained to work with robots, which can take a long time and be expensive, especially as robots are getting more sophisticated.
11. Loss of Human Skills
Degradation of Skills: As robots can handle more and more tasks, the opportunity for human workers to develop and maintain relevant skills, particularly in manual crafts or decision making roles may be lost.
Stifled Creativity: For fields that require human creativity (design, artistic or research), hyper-automation can reduce the overall level of ingenuity related to value generation in such environments.
12. Safety Concerns
Accidents and Injuries — While robots are designed to enhance safety, a malfunction or improper programming can still lead to accidents, especially in an industrial setting where the robot directly interacts with human workers.
Risk of Collaborative Robot (Robots): Robots are safe to collaborate with humans but there is still a risk that the safety system sometimes will fail so Robot maybe read wrong situational.
13. Cultural and Social Impacts
Human Interaction: Jobs that have traditionally required some human touch like caregiving, teaching, or customer service could face the risk of people being replaced with robots and not only would this decrease personal contact leading to possibly even loneliness in a world for the elderly.
More Social Inequality: The faster deployment of robots in high-tech industries will lead to even greater levels of digital divide as rich companies and countries will adopt automation sooner than others.
Summary of Disadvantages:
Costly at First: Machines such as robots have an high initial cost for their set-up, acquisition, and maintenance.
Unemployment: Robots are going to take our jobs and contribute to social inequality.
Inflexibility: Robots have difficulty performing tasks that involve creativity, adaptation, or any form of human judgement.
Relying too much on technology — Businesses might be using robots and when they breakdown, we are down.
Theft and privacy risk: Robots connected to networks can be a target of cyberattacks or may raise privacy issues.
Ethical Issued: As robots and AI development grow, they also bring ethical concerns such as jobs replaced by them for humans or using of robots in warfare.
While these hurdles are difficult to overcome, further improvements in robotics and AI will likely serve to lessen some of these disadvantages. But careful consideration of the societal, ethical and technical impacts of robots technology is also key to ensuring responsible development and deployment.
