Experience

– present

Research Assistant at Intelligent and Dynamic Systems Lab, IIT Bombay

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

–

Undergraduate Researcher at R2D2 Lab, IIT Madras

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
