Vibrations are known to cause problems in many automotive systems and industrial equipment. Therefore, vibration control devices such as traditional hydraulic dampers are used to minimize the vibrations. Off late, MR dampers, in which MR fluid is used to enhance the vibration reduction performance, are introduced. An electromagnetic piston is positioned within the MR damper cylinder that creates the magnetic field necessary to operate the MR fluid. However, due to the internal electromagnetic piston arrangement in the conventional MR damper, some serious issues like remenance phenomenon, clumping and heat effect are observed. Consequently, a modified MR damper with an external permanent magnet assembly is proposed. Viability of modified MR damper concept is checked vis-à-vis conventional MR damper. After a successful check, a handy prototype of the modified MR damper is fabricated. The performance of the modified MR damper prototype is tested by changing the MR fluid configuration, the excitation frequency of exciter, the excitation current, and the magnetic flux density. A test rig is designed and fabricated for this purpose. The MR effect on velocity and damping force in the prototype is recorded and the observations are utilised in performance optimization. The Overall Evaluation criterion is employed in the optimization process with MR fluids of 76%, 80% and 82% weight percentage of ferromagnetic particles (AMT-Dampro, AMT-Magnaflo and AMT-Smartech MR fluids respectively). The regression analysis for most suitable MR fluid configuration is also undertaken. The modified MR damper prototype is found to work effectively as confirmed by optimization and regression analysis results. The idea of the modified MR damper can be suitably applied to number of existing practical systems to handle intense vibrations.

The use of autonomous devices is becoming a common practice, mainly because it does not require human intervention and it can be applied in various fields such as agriculture, surveillance, security, exploration, personal assistance, among others. An autonomous mobile robot should be capable of determining the appropriate course of action based on the environmental information it can gather in its vicinity. This entails the ability to modify a pre-established trajectory when encountering an obstacle, while still accomplishing the assigned task through the utilization of multiple sensors and sophisticated algorithms. These sensors enable the robot to navigate, avoid obstacles, and carry out specific tasks. This document will present the implementation of an autonomous mobile robot designed for grass mowing, which utilizes various sensors including encoders, IMU, laser, and GPS for navigation from an initial point to a final destination, ensuring obstacle avoidance. The system uses a Raspberry PI 4 with ROS Melodic framework.
自主设备的使用正在成为一种普遍做法，主要是因为它不需要人为干预，可以应用于农业、监视、安全、勘探、个人协助等各个领域。自主移动机器人应该能够根据其附近收集的环境信息确定适当的行动方案。这需要在遇到障碍物时修改预先建立的轨迹，同时仍然通过使用多个传感器和复杂的算法完成指定的任务。这些传感器使机器人能够导航、避开障碍物并执行特定任务。本文档将介绍一种用于割草的自主移动机器人的实现，该机器人利用各种传感器，包括编码器、IMU、激光和GPS，从初始点导航到最终目的地，确保避开障碍物。该系统使用带有ROS Melodic框架的Raspberry PI 4。
