• Report layout and clarity

The detailed design and MATLAB Simulink simulation of control systems for regulating reactor process temperature and liquid level are shown in this research. Feedforward, cascade, open-loop, and single-loop feedback are the four control techniques discussed. By carefully building, fine-tuning, and assessing each methodology’s performance, the article sheds light on its advantages and disadvantages. A customized strategy based on a distinct physical environment (hot mixing tank) is also recommended in order to ensure academic originality when replicating the assignment.

• Problem statement

In modern industrial settings, reactor operations are widely used in chemical and medical field. Due to this, it must be carefully regulated to ensure safety, maintain product quality, and optimize resource utilization. In most chemical and thermal reactors, two critical parameters that must be strictly regulated to avoid operating risks and inefficiencies are temperature and liquid level. Inadequate control may lead to hazards like as spillage, thermal runaway, or subpar chemical process performance. The goal of this project is to develop, simulate, and assess effective control strategies for these two variables using MATLAB Simulink. The research examines several control approaches, including as feedforward, cascade, feedback (single-loop), and open-loop systems, to determine which control strategies offer the most accurate and dependable performance under different disturbance scenarios [1] [2].

Abstract — This work investigates the leader-follower formation control of multi-robot systems, an important field in robotics with broad applications in agriculture, logistics, and surveillance. The work illustrates the efficacy of geometric, potential field, and behavior-based control techniques in producing and sustaining desirable shapes through a thorough implementation utilizing the Turtlesim simulator in ROS. The technological difficulties posed by dynamic and unstructured environments are discussed, emphasizing the ongoing need for advancements in coordination and control algorithms [2] [3]. This work critically assesses the ethical ramifications of using autonomous robots in larger social contexts, going beyond their technical limitations. Safeguarding privacy to preserve sensitive data, removing algorithmic bias to ensure fairness, addressing the socioeconomic effects of potential employment displacement, and assuring safety to prevent accidents are among the main challenges [5]. The project intends to pave the road for the responsible and sustainable integration of these technologies into society, ensuring they contribute positively while reducing potential negative effects, by including ethical considerations into the design and deployment of autonomous robots.

Keywords — autonomous robots, geometric control, multi-robot systems, ROS, Turtlesim, algorithmic bias, safety, privacy, ethical concerns, urban deployment, autonomous navigation, robotic coordination, leader-follower formation control.

Abstract

This research focuses on design and stability analysis of a humanoid robot using a TonyPi model in the blender 3D simulation environment. Humanoid robots are quickly integrated into real world applications, where stability is a significant requirement under dynamic conditions. The purpose of the study is to find out how robots during simulation affect the environmental change and the object interaction balance [1]. A completely rigged 3D robot model was created and analyzed in four separate scenes: two stable and two unstable. Standing scenes involved adaptation of currency and surface friction adaptation, while unstable scenes had interesting aircraft and object conflicts. The most important simulation parameters such as frame frequency solve repetitions and replacements were adjusted to reflect realistic dynamics. The results demonstrated how physical properties and visual configurations directly affect the robotic balance. The use of blender enabled high -color visualization and dynamic testing. This study reveals the importance of simulation in robotics design and validates the aperture as a reliable tool for pre-premature verification.

The EU’s greenhouse gas reduction targets are of vital importance. To address the solution, micro-scale solutions tailored to regional needs and the cost-effective use of renewable energy sources are essential. Wind turbines (onshore/offshore) are a widely used option; the electricity they generate can be fed into the grid or used for hydrogen production via electrolysis. Tidal energy, on the other hand, stands out due to its high predictability and energy density (enabling high production with smaller turbines because water is 800 times denser than air), offering advantages such as a low carbon footprint and a 20-25 year lifespan. It holds significant potential in regions like the coasts of the UK, France, and Norway. Tidal energy has the potential to be an important component of a sustainable energy future.

Abstract

This article presents the development and implementation of a Real-Time Object Detection System, focusing on Vehicle and Lane Detection using the YOLOv4 algorithm integrated within MATLAB and Deep Learning frameworks. The primary objective of this research is to design, simulate, and evaluate an intelligent driving assistance system capable of detecting vehicles, identifying lane markings, and performing basic trajectory planning and lane change control in a highway driving scenario. The proposed system leverages a pre-trained YOLOv4 model for robust and accurate vehicle detection in real-time video streams. Lane detection is achieved through image pre-processing techniques, including grayscale conversion, edge detection, and Hough transform-based lane line extraction. Furthermore, the system incorporates trajectory planning algorithms and a basic proportional lane change controller, enabling lateral position adjustments based on detected objects and lane boundaries. A key contribution of this work is the seamless integration of object detection and lane detection outputs with control algorithms to simulate decision-making in autonomous highway driving. The performance of the object detection module is quantitatively assessed using standard metrics such as precision, recall, mean Average Precision (mAP), false positives, and false negatives. Lane detection accuracy is evaluated through Intersection over Union (IoU) metrics, demonstrating reliable lane identification even in complex scenarios. The system’s inference time was optimized to meet real-time processing requirements, achieving an average frame processing speed compatible with autonomous driving applications. Visualizations of detected vehicles, lane boundaries, and trajectory adjustments were implemented to enhance interpretability and user understanding. The experimental results validate the efficiency of YOLOv4 in vehicle detection tasks within the MATLAB environment, achieving high precision and recall rates, and demonstrate the feasibility of integrating lane detection and control mechanisms for highway lane management. However, the study also highlights areas for future work, such as enhancing the realism of vehicle dynamics models, integrating advanced decision-making algorithms, and extending the system to more complex urban environments. This research offers a foundational framework for further exploration in the field of autonomous vehicle perception systems, contributing to the development of advanced driver assistance systems (ADAS) and autonomous navigation technologies.
