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.

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.

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.
