  • Effect of infill pattern on the mechanical properties of PLA and ABS specimens prepared by FDM 3D printing
    Shishir Patel, Sneha Gupta, Harshit Saket, Kamesh Bakna, Shiv Singh Patel, Surender Kumar, Veeravalli Ramakoteswara Rao, Ravi Kumar Mandava
    Proceedings of the Institution of Mechanical Engineers Part E Journal of Process Mechanical Engineering, 2026
    Fused deposition modelling (FDM) is a three-dimensional printing technique which has become more popular and spreading in many fields. In this process, the molten thermoplastic is deposited layer by layer using a heated nozzle. Users can set the infill pattern to save the material and printing time. The main objective of this study is to investigate the tensile properties of polylactic acid (PLA) and Acrylonitrile butadiene styrene (ABS) tensile specimens with different infill patterns such as lines, tri-hexagonal and lightning. Further, the test specimens were prepared as per ASTM D638 using Ender 3D printer with varying infill patterns. The specimens were subjected to tensile tests in a mechanical tensile testing machine. It was observed that the specimens with linear infill patterns obtained higher tensile strength than the tri-hexagonal and lightning pattern infilled specimens. Later on, a microstructural study was examined on the fractured surface using scanning-electron-microscopy (SEM). It shows that the line pattern specimens have more uniform structure when compared to hexagonal and lightning pattern specimens.
  • Development of smooth, asynchronous optimal trajectories for robotic manipulators performing assembly tasks
    Srinivasulu Vardhineni, Murali Krishna Chimata, Ravikumar Mandava
    Industrial Robot, 2026
    Purpose The purpose of this study is to propose a trajectory generation method for 6 degrees of freedom manipulators that simultaneously optimizes all joint motions for point to point and multipoint tasks. Conventional methods treat each joint independently and synchronize to the slowest, often leading to suboptimal execution time and motion smoothness. The goal is to improve time efficiency and dynamic performance in industrial robotics by leveraging joint-level kinematic constraints. Design/methodology/approach A nonlinear optimization problem is formulated using quintic B-spline interpolation to generate smooth joint trajectories under velocity, acceleration and jerk limits. Segment durations for all joints are optimized simultaneously. The interior-point method is used to solve the problem. The approach is validated through simulation and physical execution on the Dobot Nova5 manipulator using benchmark point-to-point and multipoint motion tasks. Findings The proposed method yields trajectories up to 39% faster than conventional methods in point-to-point tasks. It produces smoother motions with lower peak and average jerk values, improving execution quality. In multipoint scenarios, the method reduces execution time by 3.26% compared to the synchronous B-spline method. Both simulation and experimental results confirm the method’s effectiveness and accuracy. Comparative analysis with recent trajectory planning methods further demonstrates the proposed method’s superior C2 continuity and smooth motion characteristics. Research limitations/implications The proposed trajectory optimization method considers only kinematic constraints, excluding dynamic factors such as torque limits, payload effects and actuator saturation. The framework assumes offline planning under fixed task conditions, limiting adaptability in dynamic environments. Obstacle avoidance is handled via predefined waypoints rather than integrated constraints. Although quintic B-splines offer a balance between smoothness and computational efficiency, alternative spline orders may improve performance in specific contexts. Future work will address dynamic modeling, real-time replanning and integration with collision-aware path planning to enhance practical applicability. Practical implications The proposed method enables smooth, time-optimal trajectory generation for robotic manipulators without synchronizing all joints to the slowest one, improving motion efficiency and productivity. Its asynchronous formulation allows better utilization of joint capabilities under kinematic constraints. By supporting both point-to-point and multipoint tasks, the approach is applicable to a wide range of industrial assembly operations. The method has been validated through hardware experiments, demonstrating consistent execution and repeatability. It can be readily integrated with existing robot controllers and extended with via point-based obstacle avoidance for constrained environments. Social implications The proposed trajectory planning method enhances the operational efficiency of robotic manipulators, contributing to increased automation in manufacturing and assembly tasks. By enabling smoother, faster and more reliable robot motion, it supports safer and more collaborative work environments, especially in human−robot shared workspaces. Improved efficiency and accuracy in industrial processes may reduce energy consumption, material waste and production costs. This advancement supports broader goals of sustainable automation and makes advanced robotics more accessible for small and medium enterprises, potentially impacting workforce roles and productivity in evolving industrial landscapes. Originality/value Unlike traditional decoupled methods, this unified framework globally optimizes all joint motions using quintic B-splines under kinematic constraints. The method is adaptable across robotic platforms and suitable for computer numerical control feedrate planning. It enables smooth and time-efficient trajectories for advanced industrial applications.
  • Thermal simulation and bead geometry prediction in wire arc additive manufacturing of Inconel 617
    VVD Praveen Kalepu, Kattubadi Abubakar Siddiq, Ravi Kumar Mandava
    Proceedings of the Institution of Mechanical Engineers Part E Journal of Process Mechanical Engineering, 2026
    Wire arc additive manufacturing (WAAM) has emerged as a promising technology for fabricating large-scale metal parts, offering high deposition rates, low material waste and compatibility with traditional welding systems. However, the geometric accuracy and structural integrity of WAAM materials remain highly sensitive to steep thermal gradients, particularly in dissimilar material systems, where asymmetric heat flow strongly influences melt pool behaviour. In this work, a three-dimensional, time-resolved thermal finite-element simulation involving WAAM single-layer deposition of Inconel 617 on a mild steel substrate was performed using COMSOL Multiphysics. The arc-based energy input is modelled using a Goldak double ellipsoid heat source, while temperature-dependent thermal properties and latent heat effects are included to realistically simulate melt pool behaviour. A dual-isothermal surface-based bead geometry extraction methodology is employed, using the melting range of Inconel 617 (1605–1653 K) to define bead width (BW) and bead height (BH) and the melting range of mild steel (1723–1793 K) to define penetration depth. This approach enables physically consistent identification of fully molten and thermally softened regions in a dissimilar material context, without reliance on empirical geometric assumptions. In 27 simulated cases, the BW ranged from 3.86 to 6.54 mm, BH from 2.23 to 3.86 mm and bead depth (BD) from 0.34 to 1.08 mm. The bead parameters exhibited a pronounced dependence on wire feed rate and torch travel speed, whereas the torch angle exhibited a comparatively secondary influence. Experimental measurements were used to calibrate and validate the numerical framework, demonstrating good agreement in bead geometry trends and approximate dimensions within the investigated parameter space. The model provides a calibrated thermal simulation tool suitable for parametric studies and process window analysis in WAAM of Inconel 617.
  • A Novel Review on Quadruped Robots Design Variants, Gait Modulation, and Motion Planning Schemes
    S. A. Azeez, Ravi Kumar Mandava, Nenavath Srinivas Naik
    Journal of Field Robotics, 2025
    Quadruped robots are gaining more importance among researchers due to their adaptability to complex terrains, though their stability handling is complex. Quadruped robots are one of the best kinds of legged robotic systems with regard to their framework and movement flexibility. For making quadrupeds fully autonomous, it is important to concentrate on their modeling, modulation, and maneuverability. This article sheds light on quadruped robots, starting from the early‐stage developments of TITAN series quadrupeds to current progress based on variations of design, gait analysis, control, and motion planning, so as to provide directions for future researchers to develop efficient quadrupeds. Furthermore, we have made a comparative analysis on various aspects, including various mobile robots, material specifications, leg structure and topology, crucial modeling parameters, sensors and actuation systems, as well as traditional and advanced algorithms. This work explores gait analysis, followed by numerous researchers concentrating on various gait stability challenges; in addition, it presents the studies on control strategies of quadruped robots based on a PID controller, neural network controller, fuzzy logic controller, delayed feedback controller, hybrid controller, and other peculiar controllers. Furthermore, the representative explorations on motion planning algorithms of quadruped robots have been done. To conclude, this paper provides an overview of the various variants of quadrupeds, focusing on important aspects, followed by an analysis of pivot features and providing solutions to current challenges and issues so as to help future researchers in the field identify key areas of research.
  • Optimizing PID control for enhanced stability of a 16-DOF biped robot during ditch crossing
    Moh Shahid Khan, Ravi Kumar Mandava, Vijay Panchore
    Journal of Field Robotics, 2025
    The current research article discusses the design of a proportional–integral–derivative (PID) controller to obtain the optimal gait planning algorithm for a 16‐degrees‐of‐freedom biped robot while crossing the ditch. The gait planning algorithm integrates an initial posture, position, and desired trajectories of the robot's wrist, hip, and foot. A cubic polynomial trajectory is assigned for wrist, hip, and foot trajectories to generate the motion. The foot and wrist joint angles of the biped robot along the polynomial trajectory are obtained by using the inverse kinematics approach. Moreover, the dynamic balance margin was estimated by using the concept of the zero‐moment point. To enhance the smooth motion of the gait planner and reduce the error between two consecutive joint angles, the authors designed a PID controller for each joint of the biped robot. To design a PID controller, the dynamics of the biped robot are essential, and it was obtained using the Lagrange–Euler formulation. The gains, that is, KP, KD, and KI of the PID controller are tuned with nontraditional optimization algorithms, such as particle swarm optimization (PSO), differential evolution (DE), and compared with modified chaotic invasive weed optimization (MCIWO) algorithms. The result indicates that the MCIWO‐PID controller generates more dynamically balanced gaits when compared with the DE and PSO‐PID controllers.
  • Portable coconut tree climbing device and its analysis
    Ravi Kumar Mandava
    International Journal of Industrial and Systems Engineering, 2025
    The coconut tree is one of the useful plants among all other plants. Due to the lack of coconut tree climbers worldwide, many coconut palm growers are not interested in cultivating coconut farming. Based on the above problem, numerous researchers have developed various climbing mechanisms. To overcome this problem, a novel coconut tree climbing device (CTCD) was introduced which can climb the coconut tree up to the canopy. To check the deformation behaviour and generated stresses of various parts of the device in the present research work, the authors conducted dynamic analysis, such as modal, harmonic, and transient analysis in ANSYS 2021. Moreover, the dynamic properties of each component will also be tested under vibrational excitation. Therefore, one of the vibrational properties, that is, the natural frequency, is used to analyse the effect of transient loads and avoid the noise and vibration hazards in the components of the coconut tree climbing mechanism.
  • Modelling and structural analysis of coconut tree climbing mechanism
    Pradip Solanki, Ravi Kumar Mandava
    International Journal of Engineering Systems Modelling and Simulation, 2025
    Due to the shortage of professional climbers for cutting the coconuts, many farmers are looking for coconut tree climbing mechanisms.This article aims to develop the mechanism model and examine the various types of stresses, that is, Von-misses stress and maximum shear stress, and deformation of the various mechanical components of the climbing mechanism.The mechanical parts are required to run the mechanisms are modelled individually in CREO.Further, the analysis has been conducted using ANSYS 2021.The result shows that the stresses acting on each mechanism components are less than the permissible limit of the estimated loading conditions.Therefore, it can be observed that the designed components of the mechanism can effectively withstand the load during operating conditions.
  • Design of dynamically balanced gait for the biped robot while crossing the obstacle
    Moh Shahid Khan, Ravi Kumar Mandava
    Proceedings of the Institution of Mechanical Engineers Part C Journal of Mechanical Engineering Science, 2024
    The primary objective of this research work is to generate a dynamically balanced gait for the 16-DOF biped robot while crossing an obstacle using the concept of the zero moment point (ZMP). Also, the authors discussed both the theoretical justification and its practical feasibility on real biped robot. Initially, the position and orientation of the biped robot were obtained with the help of forward kinematics while crossing the obstacle. Later on, various joint angles of the biped robot were calculated using the inverse kinematics approach. Further, the Lagrange-Euler formulation approach was employed for evaluating the dynamics of the biped robot. To generate the smooth gait of the biped robot, a cubic polynomial equation has been assigned for foot and wrist trajectories in the sagittal plane and hip trajectories in the horizontal plane. This integration allows the robot to cross the obstacles while maintaining dynamic balance, marking a significant advancement while crossing the obstacle with a height and width equal to 50 mm, which is 16.10% of the length of the robot’s leg. While crossing the obstacle, the gait of the biped robot has been considered in three stages, such as landing the foot on the obstacle, landing the foot on the ground away from the obstacle by one leg and crossing over the obstacle by another leg. A simulation study has been conducted on MATLAB to verify the dynamically balanced gait while crossing the obstacle. Finally, the generated gait angles are fed into the real 16-DOF biped robot developed by the Robotics Lab at MANIT Bhopal. It has been observed that the generated gait at three stages is more dynamically balanced while crossing the obstacle.

    Panchanand Jha, G. Praveen Kumar Yadav, Din Bandhu, Nuthalapati Hemalatha, Ravi Kumar Mandava, Mehmet Şükrü Adin, Kuldeep K. Saxena, Mahaboob Patel
    Discover Applied Sciences, 2024
    Estimation and tracking the various joints of the human body in a dynamic environment plays a crucial role and it is a challenging task. Based on human–machine interaction, in the current research work the authors attempted to explore the real-time positioning of a humanoid arm using a human pose estimation framework. Kinect depth sensor and media pipe framework are used to obtain the three-dimensional position information of human skeleton joints. Further, the obtained joint coordinates are used to calculate the joint angles using the inverse kinematics approach. These joint angles are helpful in controlling the movement of the neck, shoulder, and elbow of a humanoid robot by using Python-Arduino serial communication. Finally, a comparison study was conducted between the Kinect, MediaPipe, and real-time robots while obtaining the joint angles. It has been found that the obtained result from the MediaPipe framework yields a minimum standard error compared to Kinect-based joint angles.
