Fully autonomous electric racing team from ETH Zürich, participating in FSG

Highlights

• Developing ‘AMZ Playground’ – extensible web application for visualization, simulation, and analysis
• Overseeing software infrastructure, autonomous computer, and track-tools work packages
• Developed ‘amz-tool’ to aid developers with updating dependencies, formatting, linting, and other functions
• Coordinated autonomous software development, maintained FSSIM (Formula Student Simulator)
• Setup and maintained self-hosted continuous integration (CI) servers for automated testing and feedback
• Designed and built ground truth mapping device (GTMD) to tag racetrack using Real-time kinematic (RTK) service

The Mars rover team of IIT Madras which engineers a powerful semi-autonomous all-terrain vehicle for the scientific exploration of Mars

Highlights

• Lead the Chassis Design for the first version of the rover
• Successfully headed the team and participated in the University Rover Challenge 2017
• Conducted a successful crowdfunding campaign, raising INR 1.75L ($2700) and efficiently administered team finances
• Networked with companies - Maxon and Pololu - for accessing excusive discounts on their products
• Co-heading the design of TeRA – Tele-operated Robotic Arm, a unique manipulator constructed for rover with end-to-end design analysis

Design of Biped Test Bench for underactuated control

Highlights

• Designed bipedal robot and a rotating testbench for conducting experiments on locomotion
• Setup simulation environment and interfacing hardware and developing control architecture for the biped

Knee joint mechanism for providing natural gait among patients with weak knee extensors

Highlights

• Devised an electromechanical clutch-based mechanism for achieving selective unlocking the orthoses and performed FEA for load verification
• Prototyped a sample knee joint with necessary electronics for validating the mechanism and the control strategy
• Developed purely mechanical system to perform selective locking of knee joint
• Currently testing performance on UTM and able-bodied subjects

Novel serial chain manipulator robot with locomotion and hybrid grasping

Highlights

• Simulated PID control on model - Lagrangian Mechanics in Mathematica
• Designed and fabricated a prototype containing 2 grippers linked serial chain providing the ability to locomote, grasp and perform in-hand manipulation enabled by intricate roller belt grasping mechanism
• Experimented on the grasping force for objects of different sizes and shapes to use it as a parameter for comparison across grippers

Development of an arc welding simulator

Highlights

• Designed and fabricated Arc Welding Torch for VR simulator setup that utilizes a retracting rod mechanism for the electrode feed
• Integrated and programmed microcontroller for PID controlled retraction rate and IMU orientation feedback

Design and Fabrication of casings

Highlights
