AND

EXPERIENCE

● Ethicon Endo APEX :Designed the articulation mechanism of the APEX SC60A. Entailed design to allow rotation of the staple head in two perpendicular axes. The challenge in this work was to design a mechanism that allows the staple drive to have forward movement when the articulated staple head is at an angle.

● Bail-out mechanism in Contour curved cutter: Designed the gear train that can override and engage on the rack gear to draw the staple driver, yoke, drive bars and other parts back to the initial position. This allows reusable staples and makes the curved contour cutter reusable on the same patients.

● Design Project:Designed multi-curvature tubes to reach difficult-to-access internal organs in endoscopic surgeries. Optimized the controllability of endoscopic catheters.

● Mold compatible design of the Circular cutter(CDH) staple driver.

● Finite element analysis of the linear cutter and stapler: The analysis of the displacement in the frame of the linear cutter with the application of force was important to ensure proper alignment of the cutting blade on the groove.

● MatLab based robotic toolbox : Developed a user-friendly toolbox which analyses the following for industrial robots:

o pose using and joint velocities with inverse kinematics, the reachable workspace, plots the real-time trajectory of the end-effector and the joints.

● Intelligent Waiter Robot:Worked with First-Order Logic(PDDL) script based intelligent systems.Created a waiter robot in simulation that can take orders and cater to the customers.

● An underwater robot that maintains fixed distance from the ground during its flight through perceptions based on Visual Odometry and Visual Surveying.

● Trajectory optimization with reinforcement learning.

● UX: Creating dynamic environments(with a simulation of the physics associated, moving frames, multi-agent systems) in Gazebo.Creation of CAD models and writing XML scripts to import models to Gazebo.

● Design Project:Designed multi-curvature tubes to reach difficult-to-access internal organs in endoscopic surgeries. Optimized the controllability of endoscopic catheters.

● Currently working on autonomous UAV and drones- ROS, MavROS, PX4, OpenUAV.

● Q-learning based football player: Agent(Football player) learns about the trajectory of the ball after kick and transfer of momentum. Simulation in Vrep.

● NSF Cyber Physical System Challenge- Contestant representing DREAM lab- ASU. A drone that can autonomously identify objects and deliver them to their destination. o Currently working on perception sensors, Kalman Filters for state-estimation, Online-planning of the trajectory using Hidden-Markov Chain processes. o Involves the creation of Firmware and drivers with an understanding of the ROS architecture.
