## Headline

Mechanical System Engineer \| Mastering the Art of Developing from Scratch

## About

Mechanical System Engineer with 4\+ years of experience designing and building robotic systems from concept to deployment\. My work spans industrial robotics and soft robotics — from designing structural architectures and drive\-trains to integrating sensors, actuators, and ROS2\-based control systems\. I enjoy working at the intersection of mechanical engineering and robotics, where hardware meets software and prototypes become real systems\. I have hands\-on experience across the full system lifecycle — design, analysis, fabrication, and validation — with a strong foundation in both product development and research environments\. 🔧 Core Expertise: Structural Design & Analysis \| Drive\-train Engineering \| Robot Kinematics \| ROS/ROS2 \| Sensor Fusion \| SolidWorks \| Fusion 360 \| Python \| MATLAB \| Always excited to connect with like\-minded engineers at the cutting edge of robotics and automation\.

## Work experience

Mechanical Engineer at Spacewalk Automation, Mar 2024 \- Present · 2 y 6 mo, Bengaluru, End\-to\-end mechanical development of a KEPLER, 6\-axis industrial robotic arm, from concept to validated prototype\. Structural design, drive\-train engineering, and servo actuation system development\. Kinematic modeling, URDF development, and ROS2\-based system integration\. System validation through component\-level testing and hardware\-software integration\.

Project Assistant II at National Institute of Technology Durgapur, Sep 2021 \- Jun 2023 · 1 yr 10 mos, Durgapur, Worked on development of a wearable soft exoskeleton for assistive and rehabilitation applications, contributing across design, fabrication, and system integration\. Designed and developed textile\-based soft exosuit structures, optimizing load distribution and ensuring natural gait during assisted movement\. Fabricated and characterized hyper\-elastic pneumatic artificial muscles \(PAM\), validating mechanical performance and durability under repeated pressure cycles\. Developed a PID\-based control strategy for non\-linear PAM actuation, synchronizing assistive force delivery with the user's natural walking cycle\. Integrated FSR, IMU, and EMG sensors for real\-time gait analysis and user intent detection, enabling adaptive assistive response\. Deployed ML\-based intent detection models on embedded platforms using ROS, enabling real\-time closed\-loop control of the exosuit\. Contributed to system\-level validation, achieving measurable reduction in muscle activity during assisted walking trials\. Co\-authored multiple international conference publications in soft robotics and assistive systems based on research outcomes\.

Project Student at CSIR\-Central Mechanical Engineering Research Institute \(CMERI\), Nov 2020 \- Jul 2021 · 9 mos, Durgapur, Designed and analyzed hyper\-elastic pneumatic actuators using Abaqus FEA, evaluating non\-linear deformation behavior under varying pressure conditions\. Developed and characterized soft material\-based force sensors for real\-time interaction force measurement\. Investigated mechanical behavior of hyper\-elastic materials and validated simulation results against experimental data\. Prototyped a sensor\-integrated soft bending actuator for medical applications, enabling real\-time force feedback during navigation\. Gained foundational expertise in soft robotics, pneumatic systems, and non\-linear material mechanics that shaped subsequent research work\.

Summer Intern at Indian Institute of Technology, Kharagpur, Jun 2019 \- Jul 2019 · 2 mos, Kharagpur, Developed initial design architectures for a wall\-climbing robot, focusing on locomotion and surface adhesion mechanisms\. Utilized Autodesk Inventor for 3D modeling and assembly, optimizing component layouts for structural integrity and weight reduction\.

## Education
