  • Mechanical Design Modelling and Analysis of a Human Hand Fingers for Developing Rehabilitation Exoskeleton
    R. Rangan Prashanna, K. Nithish, S. Vaisali, C. Maheswari, S. Babu Ramesh
    Journal of Engineering Science and Technology Review, 2026
    A human hand, especially one with many fingers, is necessary and indispensable for carrying out a variety of gripping duties which we constantly use in daily life.Motion disorders have grown, and finger joint strength has decreased due to an increase in accidents and strokes.Despite the growing popularity of robot hands, the hand's design continues to be influenced by the creators' inspiration and expertise.When striving to give robot hands the dexterity, strength, and flexibility of human hands, engineers face a challenging dilemma; frequently, some qualities are sacrificed to create place for others.Since there have been many exoskeleton models conceived, created, and tested in recent years, it is crucial to comprehend the dynamics and kinematics of the joints in the human fist and digits in order to create such devices and enable safe motion along planes.In order to assist researchers in creating assistive and rehabilitative robotics and gadgets, the initial section of this work intends to provide a model for the arrangement of human fingers in the hand and fist.The second section compares the human hand and Aluminium 7079 for the same construction using various static and dynamic analyses, mathematical modelling, and hit impact velocity mapping.The human hand is a complicated mechanism that is challenging to imitate and model since it includes all of the joint characteristics.Designing the hand structure requires a dynamic analysis since the usual physiological motions of the hand necessitate dynamics.
  • Exo skeleton pertinence and control techniques: A state-of-the-art review
    Prashanna Rangan R, Ramesh Babu S
    Proceedings of the Institution of Mechanical Engineers Part C Journal of Mechanical Engineering Science, 2024
    Exo-Skeleton is a wearable robotic device which was emerged in later 1960s that has a multitude of applications ranging from weightlifting to wearer’s stability improvement. This paper makes a novel approach in reviewing the various exo-skeleton models that are available at the present. The idea of this paper is to study and compare the models in terms of medical applicability like gait rehabilitation, physiotherapy, human strength augmentation, various control strategies of exo-skeleton, ergonomic study, and need for exo-skeleton system for enhancing the life of humans. Since exo-skeletons are wearable devices, it requires precise controlling of the actuators and repeatability, and accuracy plays a vital role. The paper elucidated with a detailed analysis, reviewed and summarized the core essence of 300 research papers and patents in the field of exo-skeleton with the aforesaid aspects of application and drive system with their control methodologies from 2007 to 2022 and shown a trend with year-wise data from which it is clear that the future of industrial work will become a collaborative activity involving the exo-skeleton system with human labours. Human – robot interaction is vital and must for enabling an integration which can be achieved with the amelioration in the control and actuation techniques for precise control. With the furtherance in the technology the exo-skeletons can be purpose built that can be of rigid or flexible structures with active, passive, or quasi-passive controls based on the user needs. Joint handed operation of Exo-skeleton with the alternative treatment methodologies will yield a plethora of benefits in the near future in comparison with the present conventional treatment modes that could result in reduction of surgeries.
  • Performance Metrics in Digital Supply Chain Paradigm
    R. Prashanna Rangan, R. Kumanan, K. Ram Prasad, M. Nishal
    Environmental Footprints and Eco Design of Products and Processes, 2024
    Globalisation in corelation with technology development has recently made it possible to compete in business and prosper. Digital technology must now be included by companies if they are to remain sustainable and globally competitive. The fourth industrial revolution has altered how individuals interact with their surroundings and communicate. The supply chain has begun to be digitalised in order to accommodate digital goods and services as internal business processes change so quickly. Innovative strategies, including technologies for digital transformation, are required to obtain an advantage in the digital supply chain. Current methods for global supply chain management and logistics for moving, storing and managing cargo are not suitable for the future from an economic, environmental or social standpoint. To assess how effectively a company is performing in achieving its goals, supply chain metrics and performance measures obtained through benchmarking are essential. Monitoring a company's operations, performance and behaviour is made possible via performance metrics. They ensure that the supply chain is controlled and operating efficiently by enabling visibility into key operations. This chapter provides insights into the performance metrics which control the supply chain activities internally and externally. The Key Performance Indicators known as KPI’s which drive the organisation towards its intended results have been listed, and their significance towards the digital supply chain has been elaborated in detail. The measurements can be used to determine inventory accuracy, turnover and inventory-to-sales ratios. Therefore, by monitoring supply chain indicators, a business may quickly pinpoint areas that require improvement or where supply chain effectiveness may be increased. To maximise the gains of implementing a Digital Supply Chain (DSC), it is crucial to identify all of the potential opportunities, pain spots, difficulties and development chances beforehand.
  • Design and Modelling of a Human Upper Limb for Rehabilitation Exoskeleton
    Rangan R Prashanna, Joe Johnson, Babu S Ramesh, C. Maheswari, S. Vaisali, S. Shankar
    Journal of Engineering Science and Technology Review, 2024
    Electromechanical systems that interact with the user to offer power amplification, assistance, or replacement of motor function are known as exoskeletons for the upper limbs.The upper extremity rehabilitation exoskeletons have garnered increasing attention and impact in the healthcare sector over the past years due to the advancements in the field of robotic control devices and actuation elements.The necessity for assistive supporting and rehabilitation devices that either help improve human strengths or provide assistance in regaining lost motion of a specific limb joint arises as a result of changing trends and a growing population.Age-related bone loss often results in weaker, more fragile bones that make lifting and carrying huge loads more difficult.A stroke can impair mobility and is more likely occurs to the elderly people.Accidental paralysis as well as other health issues including spinal cord injuries, musculoskeletal disorders due to work environment are on the rise resulting in an increased urge for the assistive devices.The motive of this paper is to design a mathematical model of the human upper limb involving DH parameters and forward kinematics alongside with the human joint study to precisely design the model in order to design an upper extremity exo-skeleton for offering limb rehabilitation considering the human joint constraints with respect to the Sagittal, Coronal and Transverse planes.This study is aimed in providing a significant vision in developing the precise rehabilitation devices that can aim in offering the joint specific treatment to the user for human upper arm therapy.

  • Studies on wire arc additive manufacturing of shape memory alloys
    Rangan R Prashanna, Gurusamy Visvanathan, Mohandass Muthukrishnan, K Pitchandi
    Mechanical Properties and Characterization of Additively Manufactured Materials, 2023
    Shape memory alloys (SMA) are revolutionary metallic materials. The SMA will be deformed under external force and when heated, they can revert to their original shape. Because the yield strength of SMA is relatively low at lower temperatures, they can be exposed to very easy deformation below their transition temperature. When heated above the transition temperature, the crystalline structure changes and the materials return to their previous shape. If the SMA finds any impediment during this conversion, extremely huge forces will be created. This exceptional property provides a one-of-a-kind method for remote actuation. Because of their shape memory and super-elastic capabilities, they have gained a lot of interest for biomedical and aeronautical applications. On the other hand, traditional manufacturing of components using shape memory alloys presents substantial issues for the most common SMAs, such as nitinol and Cu-based materials, such as poor machinability and perhaps high tool wear. By eliminating the requirement for tooling and permitting the fabrication of components directly from Wire Arc Additive Manufacturing (WAAM), these challenges have been addressed effectively.

    R.Prashanna Rangan, C. Maheswari, S. Vaisali, K. Sriram, Albert Alexander Stonier, Geno Peter, Vivekanada Ganji
    Medical Engineering and Physics, 2022
    Over the past few years the growth and development of exo-skeleton has dramatically raised with the development of precise control elements and actuation systems. Many exo-skeleton systems have been designed, developed and tested for performance optimization. In the recent years, the significance of exo-skeleton in medical fields have got increased and are used in providing therapy and rehabilitation to the patients. With this development there comes the importance for analysis and control of the exo-skeleton for precise functioning and to avoid malfunction of the system in the later part. Dynamic analysis of limb joints is essential to better facilitate a deeper understanding of the exo-skeleton limb during various environmental conditions like varied loading. The dynamic model so developed will assist in choosing an apt actuation system based on the torque requirement of the model.This paper focusses on the analysis of a 2DOF lower limb active control exo-skeleton system and makes a torque calculation for actuator selection for the lower limb to provide rehabilitation to the patients as wearable walking aid. The work also makes a trajectory planning for the lower limb to move in sequence for making a walking cycle with angular limitations to avoid damage to the user's limbs. The motion analysis for the developed lower limb Exoskeleton as per the analysis is 52.055 Nm at hip joint 11.677 Nm at knee joint.
  • Human Upper-Extremity Rehabilitation Trainer (Hurt)
    Rangan R. Prashanna, S. Vaisali, C. Maheswari, S. Shankar, Albert Alexander Stonier
    Journal of Engineering Science and Technology Review, 2022
    With the evolving trends and growing population there arise the need of assistive supporting and rehabilitation devices which are either used for improvising the strengths of the human or to offer an assistance to regain the lost motion of a particular limb joint. Particularly the musculoskeletal diseases are getting increased in the younger age due to work environment and aging and as a consequence the need of assistive devices is on the rises. The current demand is for designs that are adaptable and affordable, and for these designs, design perspectives must be considered in order to create fewer complex designs and ease production restrictions. The paper proposes a novel idea to offer rehabilitation to the lost motion on the human upper limb and develops a cost-effective upper extremity exo-skeleton to address the post stroke patients. Design analysis is carried out to obtain the important joint motions for offering rehabilitation to the user with easily available components in an affordable way. The Degrees of Freedom with respect to the human upper limb joint is kept in mind in designing the model to offer effective rehabilitation at minimal cost. The developed model is a self-sustaining, battery-operated and detachable design which can be placed in compact places.

    Journal of Engineering Science and Technology Review, 2022
    Humans could not traverse to every point on the surface, yet they still require information about such locations, such as in the fields of astronomy, geology, the military, etc. As a result, researchers have designed cutting-edge technologies have enabled data gathering from locations where humans are unable to travel. Our research is one of these technologies, and it is extremely useful in a variety of applications, including remote sensing and evacuation. A quadruped robot bio inspired from the spider structure with 3 Degree of Freedom for each leg is fabricated. Structure is so chosen that offers a good manoeuvrability on uneven surfaces thus offering it a biological resemblance of a spider. searching for survivors in war zones, examining precarious structures after natural disasters like earthquakes, tsunamis, or volcanic eruptions, taking pictures of dangerous wildlife like lions and tigers, etc. are all examples of exploring risky locations for humans for which the proposed model offers a solution.
