In hospitals, bus shelters, retail malls, and many other business locations, conventional floor cleaners are most frequently employed. These gadgets can't be utilised since they need electricity to function. In India, there is a power crisis, particularly in the summer, and due to this issue, most floor cleaners are not used efficiently, especially around bus stops. The creation of an accessible, user-friendly floor cleaner is therefore necessary. The goal of this project was to create a manual floor washer as an alternative to current floor washers. Using the relevant commercial software, modelling and analysis of a floor cleaner were carried out in this work. The utilisation of conventionally used materials was taken into consideration when designing the floor cleaning machine. The voltage level of the manual floor washing machine is within the safe range, according to the analysis of the element.

Rail transportation in India is at the forefront of providing the necessary transportation infrastructure to satisfy the demands of a quickly expanding economy. India currently has the fourth-largest rail network in the entire world. Yet, we have not met international standards in terms of dependability and safety in railway sector. The biggest challenge in conducting a railway analysis is identifying structural flaws. They risk straying and losing their intended course if not properly managed. The proposed device is appropriate for rail transportation since it allows for the early detection and prevention of accidents. This will be installed on the train engine for the user to use the crash sensor. As a result, if a specific crack is discovered on the trail, the train automatically slows down and stops somewhere, and the exact location of the crack is communicated to the control room. Second, the subsequent cause of accidents is avoided by using identical sensors installed on the engine of two vehicles travelling down the same road. The sensor detects the same signal from a different vehicle and automatically applies the brakes and stops the vehicle at a specific distance. Train diversions might take advantage of several losses from train accidents.

—This paper deals with the path planning of autonomous differential driving wheeled mobile robots. The path planning controller of the mobile robot is designed based on the chaotic behaviour of the Triple Pendulum (TP). The dynamic response of the TP is investigated using Simscape Multibody software. The chaotic behaviour of the TP is examined with a 0-1 test. The proposed model was tested with five different scenarios. In each experiment, the robot is designed to search for a target that may represent an exit point, dangerous material, or any specific target. This target is placed in an arbitrary position on a square arena 2500 mm by 2500 mm. In order to increase the complexity of the robot mission, the target is surrounded by an obstacle (u-shape) so that there is a unique entrance for the robot to reach the target. In addition, the proposed controller is compared with the controller based on a traditional chaotic system (Lorenz system), which is designed for this purpose. In this work, simulation results are conducted using the KiKS simulator. The results show the success of the proposed controller in completing all missions with 13.11 sec, 17.09 sec, 36.47 sec, 12.52 sec, and 12.49 sec for scenarios 1, 2, 3, 4, and 5, respectively. The second controller completed the same mission in 25.22 sec, 32.28 sec, 46.49 sec, 49.4 sec, and 33.38 sec. These results proved the proposed controller's advantage, which has great potential and can be investigated in the future.

—The importance of automated guided vehicles is increasing in flexible manufacturing systems as they are flexibly to change in facilities and factory layouts. This study proposes a transport route that introduces a roundabout and a one-line through method based on the knowledge of transportation systems, to prevent interference between AGVs under irregular transport requirements and to achieve high transport efficiency. AGVs are required for irregular transportation, and stopping multiple AGVs. Due to interference between them during operation is a challenge that should be prevented because it will stop the production line and reduce production efficiency. The locations where speed differences occur are where the AGVs receive and deliver the materials to be transported. We will apply the knowledge of traffic engineering to improve the efficiency of transportation, and also adopt indices obtained from the knowledge of traffic engineering to evaluate transport efficiency.

— The aerodynamic performance of airfoils has been studied in several studies; however, the performance is highly relying on the airfoil geometry and the flow characteristics such as the flow type (laminar or turbulent) and Reynolds number. This paper focuses on understanding the aerodynamic performance of airfoils in a low-speed environment (low Reynolds number) versus the airfoil geometry. This paper would be a guide to the airfoil design and optimization processes toward the design target under similar flow conditions. Therefore, several parameters of the airfoil geometry, such as maximum thickness, maximum camber, their location, and reflex angle were studied in a low Reynolds number range from 0.3×10 6 to 0.8×10 6 . Three airfoil parameterizations, NACA 4-digit, PARSEC, and Bezier curve, were utilised to generate the airfoil coordinates for different studied parameters. A two-dimensional aerodynamic solver, XFOIL, was used to evaluate the aerodynamic performance of the airfoils. The results show that varying the airfoil geometry results in a noticeable change in the lift, drag, and moment coefficients. Also, as expected, increasing the Reynolds number has resulted in a good performance.

—Cable-Driven Parallel Robots (CDPR) have recently been applied in a variety of industries. Particularly in specialized industrial fields where dynamic features such as high precision in systems demand quick transitions so that cable-driven parallel robots have been deployed. The cable force is the most important factor influencing the control algorithm of the cable-suspended parallel robot. The cable force at the attachment point of the cables at the platform and the winch are different. Due to friction, the pulleys between the force sensor and the platform affect the force measurement accuracy. This disparity is caused by a variety of factors, including high acceleration, stiffness, cable density, and cable length. In this paper, a dynamic model and cable tension are designed for cable transmission to increase the accuracy of cable forces. The influencing variables of the cable force during motion are defined by studying the force relationship of the cable. Finally, experiment and numerical simulation are used to verify the correctness of the research content in this study. The results show that the model can accurately simulate the force state of the cable compared to the actual force measured at the load cell.

—Applying control algorithms in a decentralized manner to large-scale robot systems is a growing area of research in swarm robotics. However, due to the manufacturing and installation costs, implementation time, and user operating limitations on large-scale swarm robots, the experiment’s applications in these studies are currently relatively constrained. Most proofs of the algorithm’s viability in these studies end with simulations or implementations on a small number of robots. Following the majority of platforms for swarm robots shown in previous studies, a design of our low-cost small mobile robot platform, the Millibot, which is consistent with those algorithms for mobile robot swarms is introduced in this work. Moreover, in an effort to allow operation easier for users, even when the robot swarm consists of hundreds of individuals, fundamental swarm scalable functions consist of scalable user-assigned power mode, automatic charging and scalable upgrade firmware operation will also be introduced and implemented to swarm of Millibot. The results show that using proposed platform enables users to build and control swarm robots of up to hundreds of individuals.

—A spoiler installed in a hard disk drive can reduce the airflow velocity that causes vibration at an actuator arm and its head. In the case study, a hard disk drive manufacturer identified the defect of a loosely tightened spoiler in the hard disk drive by the spoiler installation machine. This occurred as a result of incorrect screw spacing (also called ‘the screwdriver encoder’). There was no study that specifically specified or created a suitable relationship model between the screwdriver encoder and associated parameters for the installation of a spoiler. Factors affecting the screw spacing were determined using multiple regression analysis, and a mathematical model of the significant factors of the screwdriver encoder was built. Data were collected from the spoiler installation machine and its software. Four factors were identified with the potential to impact the screwdriver encoder as (1) vacuum level for picking up the screw, (2) time spent in tightening the screw, (3) bit angle, and (4) screw torque. The ANOVA results pointed out that the screw torque within the range of experimental values did not affect the screw spacing, and a quadratic regression model was the most appropriate under various statistical criteria. This research demonstrated that a sophisticated regression model, i.e., a cubic model, is not always a good choice for an agent. In addition, the optimal values for the spoiler installation machine were determined. The faults decreased by 0.0096% from 0.055% each month. For choosing the relationship model of additional workpiece screw tightening variables, this research phase can be utilized as a guideline.

— Despite the flexibility in the stamping process with complex ram movement, commercial servo presses are still expensive for the affordable of medium or small enterprises. Moreover, since the movement of the ram can be precisely controlled, these systems also require high maintenance and even highly skilled workers to operate. This study proposes a design for multi-stroke forging machines, which combines a gear transmission and a 6-link mechanism to control the stroke for the ram. Experiments with several design parameter sets prove the possibility of modifying the complex movement of the rams only by changing the gear ratio and angular difference between diving shafts. Results obtained from the calculation also indicate the applicability of the proposed system in multi-stage forging and support the designing process to get complex strokes of the ram.
