Designing green robots with environmental sustainability by applying the concept of multi-criteria decision making V. Sathiya, S. Mahalakshmi, S. Ramabalan, M. Chinnadurai Scientific Reports, 2025 To ensure environmental sustainability, cutting-edge technologies and market-oriented products are made eco-friendly. In this regard, several studies have been carried out by many researchers. However, Green Robotics (GR) has to be explored well. It requires more research. This study attempts to examine the performance of GR with two real-time applications. Also, the correlation between GR, Green Supply Chain Management (GSCM), green computing, and the approaches used to increase sustainability in robotics are analyzed. The adoption of green notions in the entire development cycle of a robot (from robot design to its application) is addressed. The measures employed to evaluate green models are selected to assess the effectiveness of the processes related to green computing, selection of green material, and reduction in energy and cost. Two tangible educational Mobile Robots (MRs) are designed using a hybrid MCDM technique. The research problem is addressed using a hybrid methodology integrating Analytic Network Process (ANP) and Interpretive Structure Modelling (ISM). The empirical results prove the proposed method performs well. This study about Green Robotics plays a vital role in sustainability by encouraging eco-friendly materials, reducing energy use, enhancing the efficiency of resources, reducing wastage of resources, reducing our footprints on ecosystems, promoting sustainable manufacturing strategies, and working together with other eco-friendly methods.
An experimental investigation on copper square electrode wear in electric discharge machining of Hastelloy B2 S. Ramabalan, N. Ramasubbu, P. Velvizhi, V. Sathiya Scientific Reports, 2024 Hastelloy B2 is a high-performance nickel-molybdenum alloy and has been used in micro reactor, pump, pipe, and corrosion-resistant equipment. Square holes are required in the above application components. Although square holes are easily produced by spending more electrodes wear in Electrical Discharge Machining (EDM). Moreover, the square hole with small electrode wear achieved is a challenging task in thermal machining. Hence, in this work, the effects of EDM process parameters on electrode taper angle, electrode radius, electrode wear length and cutting time of Hastelloy B2 are studied. Taguchi based VišekriterijumskoKompromisnoRangiranje (VIKOR) method is used to find the optimum process parameters and compared with Taguchi based Grey Relational Analysis (GRA) method for validation. The results showed that current and pulse duration greatly affects the electrode wear out surface and edges. The square electrodes with sharp edges and surfaces are fully transformed into hemispherical shapes at electrode ends due to an unstable spark with diffusion of heat. Also, the VIKOR method provides an alternative multi-criteria optimization method that enhances the process performance over the grey relational analysis due to comparability, uniqueness, assessment and prediction.
Mobile Robot Multi-Objective Trajectory Planning with Velocity obstacles V. Sathiya, S. Ramabalan, S. Mahalakshmi, K. Nagalakshmi 2nd International Conference on Emerging Trends in Information Technology and Engineering Ic Etite 2024, 2024 A velocity obstacle crossing the paths of Mobile robots is a general situation in both indoor and outdoor environments. Velocity obstacles reduce or alter the speed of the robot. The prediction of exact trajectory for the robot motion by the currently available methods is to be improved a lot. This gap is to be addressed. This manuscript proposes two multi-objective optimization methods based on evolutionary algorithms to bridge the gap. Evolutionary algorithms - Multi-objective Differential Evolution (MODE) and Elitist non-dominated sorting Genetic Algorithm (NSGA-II) are proposed in this paper. A car like mobile robot is designed, fabricated and experimented. Travel time and energy spent are considered as performance criteria in the problem solved by the proposed algorithms. Dynamic parameters' limitations, geometrical parameters' constraints and kinematic characteristics' bounds are considered in the problem. Both fixed and moving obstacles were present near the robot in its environment. So, motion of both obstacles was considered by the algorithms while planning the path of the robot. A third order NURBS function is used to characterize the mobile robot's trajectory. The optimal trajectory for the mobile robot was found by both NSGA-II and MODE. Experiments also conducted to validate the algorithms' results. Experimental validation proves that both NSGA-II and MODE are good algorithms to consider for optimal trajectory planning of mobile robots while considering stationary obstacles.
Optimum Design of Stair-Climbing Robots Using Taguchi Method A. Arunkumar, S. Ramabalan, D. Elayaraja Intelligent Automation and Soft Computing, 2023 Environmental issues like pollution are major threats to human health. Many systems are developed to reduce pollution. In this paper, an optimal mobile robot design to reduce pollution in Green supply chain management system. Green supply chain management involves as similating environmentally and economically feasible solutions into the supply chain life-cycle. Smartness, advanced technologies, and advanced networks are becoming pillars of a sustainable supply chain management system. At the same time, there is much change happening in the logistics industry. They are moving towards a new logistics model. In the new model, robotic logistics has a vital role. The reasons for this change are the rapid growth of the e-commerce business and the shortage of workers. The advantages of using robotic logistics are reduction in human errors, faster delivery speed, better customer satisfaction, more safety for workers, and high workforce adaptability. A robot with rocker-bogie suspension is a six-wheeled mobile platform that has a distinctive potential to keep all wheels on the ground continuously. It has been designed to traverse rough and uneven terrain by distributing the load over its wheels equally. However, there is a limitation to achieving high-speed mobility against vertical barriers. In this research, an optimal design of product delivery wheeled robots for a sustainable supply chain system is proposed to ensure higher adaptability and maximum stability during climbing staircases. The design parameters of the proposed robot are optimized using Taguchi Method. The aim is to get a smooth trajectory of the robot’s center-of-mass. The proposed approach realizes a robot with much-improved stability which can climb over heights more than the size of the wheel (i.e., 3 times the radius of wheels). The results reveal that the modified rocker-bogie system not only increases the stair-climbing capability but also thwarts instability due to overturning of a wheel of the robot.
Development of a fuzzy logic model for the prediction of spark-ignition engine performance and emission for gasoline-ethanol blends Manikandan Kaliyaperumal, Ramabalan Sundaresan, Balu Pandian, Silambarasan Rajendran Green Processing and Synthesis, 2023 Due to the enormous of fossil fuels and the ensuing increase in automobiles, an unprecedented scenario has arisen with pollution levels that are out of human control. In this study, a fuzzy logic model is developed to predict how well a spark-ignition engine running on gasoline and ethanol mixes would operate. A test engine was operated on pure gasoline and gasoline–ethanol fuel mixtures in a range of ratios at varying engine speeds. In order to estimate outputs such as brake-specific fuel consumption (BSFC), brake thermal efficiency, nitrogen oxides (NOx), hydrocarbon emissions, and carbon monoxide, a fuzzy logic model, a sort of logic model application, has been developed using experimental data. The developed fuzzy logic model’s output was compared to the results of the trials to see how well it performed. The output parameters were indicated, including braking power, thermal, volumetric, and mechanical efficiency. The input parameters were engine speed and ethanol mixes. Regression coefficients were nearly equal for training and testing data. According to the study, a superior method for accurately forecasting engine performance is the fuzzy logic model. To eliminate proportionality signs from equations, regression analysis is used. It is accurate to develop mathematical relations based on dimensional analysis. Based on the root mean square errors, BSFC is a minimum of 6.12 and brake power is a maximum of 8.16; lower than 2% of errors occur on average.
