Cognitive System and Robotics Final Report

Introduction

The interrelationship between the artificial intelligence (AI) and robotics is fundamental to the development of autonomous human-robot systems. While AI provides the cognitive capabilities for perception, decision-making, and learning, robotics offers the physical capabilities for interaction with the real world. Cognitive technology is a field of robotics concerned with endowing a robot with intelligent behavior by providing it with a processing architecture to the chosen environment (Cangelosi & Asada, 2022). The cognitive systems allow the robots to learn and reason about how to behave in response to complex goals in a complex world. However, the technologies driving these systems have their strengths and weaknesses, and addressing these challenges is crucial for advancing the field and ensuring the safe and effective integration of robots into society (Krishna Pasupuleti, 2024). Thus, the paper will present a report that was prepared after designing design and implementing a routine for a robot in Webots. The report will focus on discussing how the task performed by the designed robot, its significance, challenges faced, and potential real-world applications.

The project demonstrates an integration of robotics, computer vision, and machine learning to achieve autonomous navigation and object recognition. The robot was equipped with various sensors and a camera to follow objects and predict numbers.it was designed to processes camera data to predict a number using the logistic regression model. The robot starts and initializes its sensors and wheels for movement which are used to rotate to face north and follows any recognized object until it reaches the specified proximity. Upon reaching the object, the robot captures an image, processes it, and predicts the number using the logistic regression model. The robot then centers itself and repeats the process for east, south, and west directions (Krishna Pasupuleti, 2024). The process continues in a loop, allowing the robot to navigate, follow objects, and predict numbers autonomously.as a result, the developed routine aimed to create a highly capable and autonomous robot that can navigate its environment, recognize and follow objects, and predict numbers with high accuracy. The project integrates object recognition capabilities to identify and follow objects with specific colors and predict numbers on them, showcasing the application of cognitive systems in visual processing and decision-making.

Literature Review

Many researchers and practical applications in cognitive systems and robotics have demonstrated that the Artificial Intelligence (AI) and robotics are intrinsically linked. AI provides the "brain" for robots, enabling them to make decisions, learn from experiences, and adapt to new situations, while robotics offers the physical "body" that executes tasks in the real world (Soori et al., 2023). For instance, the AI techniques such as computer vision and sensor fusion help robots perceive and understand their environment. AI algorithms process data from cameras, radar, and other sensors to identify objects, navigate spaces, and interact with humans and other objects. Similarly, the AI-driven algorithms such as machine learning, deep learning, and reinforcement learning, allow robots to make informed decisions and plan actions. These technologies enable robots to optimize paths, avoid obstacles, and perform complex tasks autonomously.

The research also shows that robotics relies on AI for precise control of actuators and motors. AI models help in controlling movements, ensuring smooth and accurate execution of tasks, and adjusting actions based on real-time feedback. According to Tawiah, (2022), the cognitive system used through AI enhances the interaction between humans and robots. For instance, the natural language processing (NLP) and speech recognition enable robots to understand and respond to human commands, while AI-driven emotion recognition helps robots to interpret and react to human emotions. Additionally, the AI allows robots to learn from their experiences and adapt to new environments and tasks. Machine learning algorithms enable robots to improve their performance over time without explicit programming for every new task.

Robots have been extensively used in manufacturing for tasks such as assembly, welding, painting, and quality inspection. Cognitive robotics is a form of embodied cognition which exploits the robot's physical morphology, kinematics, and dynamics, as well as the environment in which it is operating, to achieve its key characteristic of adaptive anticipatory interactions. Cognitive robots are highly efficient, capable of performing complex tasks in less time, often surpassing human capabilities (Tawiah, 2022). The efficiencies precision and consistencies make cognitive robots cost-effective over time, even with initial investment costs. According to Krishna Pasupuleti, (2024) the research, Artificial Intelligence (AI) models and architectures add significant value to interactive systems across various domains. However, the value of the robot can be critically appraised by examining the enhancements in user experience, efficiency, personalization, scalability, and decision-making capabilities.

Robots have been extensively used in manufacturing for tasks such as assembly, welding, painting, and quality inspection. Collaborative robots work alongside humans, enhancing productivity and safety while the human-robot models and architectures have a broad and growing range of applications in industrial and commercial environments. The effectiveness and benefits of utilizing the robots are evident in increased efficiency, precision, and cost savings across various sectors. However, limitations such as high initial costs, integration complexities, and ethical considerations must be addressed. The future of the applications lies in overcoming these challenges through technological advancements, regulatory support, and societal acceptance, paving the way for more widespread and effective deployment of human-robot systems.

Description of implementation

The project integrates object recognition capabilities to identify and follow objects with specific colors and predict numbers on them, showcasing the application of cognitive systems in visual processing and decision-making. The robot was equipped with various sensors and a camera to follow objects and predict numbers. The robot uses a logistic regression model for number prediction, which is loaded at the beginning. The main functions involve rotating the robot, following objects, processing images, and predicting numbers. It was designed to utilize sensors and actuators such as inertial unit, GPS, distance sensors, ground sensors, and the camera. The feature made it possible to develop the robot’s ability to autonomously navigate its environment using sensors and a pre-defined routine. The project also implemented robust image processing techniques to convert camera data into a format suitable for the machine learning model. The model combines data from various sensors (inertial unit, GPS, ground sensors, and camera) to enhance the robot's decision-making and navigation capabilities.



The project also implemented object recognition capabilities using the robot's camera to identify and track objects with specific colors.it was designed to ensure precise movement and positioning using yaw data from the inertial unit and proximity information from distance sensors. The system was also designed to initializes the motors for the robot's wheels to allow movement. It also utilizes the utility functions such as “wait” to pause the robot, ‘get_yaw’ to get the current orientation, and “rotate_to” to rotate the robot to a specified direction. The project was also designed to utilize the movement functions to turn the robot in specific directions. The functions included the “followObjectUntilDestination” which allows the robot to follow an object until it reaches a specified tolerance.

 The project also integrated a pre-trained logistic regression model to predict numbers on objects based on images captured by the robot. The functionalities also included the “processObject” which captures an image, saves it, and predicts the number using the logistic regression model. The function “predict Number” was also implemented to processes camera data to predict a number using the logistic regression model. Similarly, the funtion “centerLocation” was implemented to reorients the robot based on ground sensor readings. The main loop directs the robot to follow objects in four directions (north, east, south, and west) and reorient itself after each movement as shown by the image above. It processes objects and predicts numbers at each destination
