• Stable walking, turning and trotting gaits were achieved by analysis of stability triangles using MATLAB considering time period, duty factor, phase difference between ipsilateral and contralateral legs.
• Control simulation by co-simulating in ADAMS-MATLAB where the robot in the ADAMS environment is controlled by the control model in Simulink
• Walking stability was achieved in the co-simulation. Show less

• Designed and prototyped the variable active steering system whose steerability depends on the speed of the vehicle.
• Planetary gears were used to achieve the active system.

Design, analysis and fabrication of powertrain an All Terrain Vehicle according to BajaSAE India rules. Involved in calculations of gear ratio,acceleration, gradability and torque requirement, design and manufacture of driveshaft and universal joints.

• Analysis of the motion of four-bar, Slider Crank, Double Slider, Scotch Yoke mechanisms. The mechanisms were simulated in Wolfram Mathematica.
• Using position analysis techniques and toggle as the constraints, the range of transmission angles were defined for a four-bar by solving Freudenstein equations. Established a distinction between Grashof and Non-Grashof conditions.
• Constraining a particular point on the coupler link to follow a path, a four-bar mechanism was also designed… Show more

• Constraining a particular point on the coupler link to follow a path, a four-bar mechanism was also designed. The link lengths were obtained by solving the vector loop equations, with the position of pivots of the frame and the points on the path being known with respect to a reference point. Acceleration and velocity analysis of various points on the links were also performed. Show less

Conceptualized and designed the product, Clothes Retrieval System which prevents hung clothes from getting wet during rain without human intervention. It was designed purely based on the principle of electrolysis and no electronic sensors were used. The simplicity of the concept got us the bronze medal at the Intel IRIS National Science Fair held at Delhi on November 25th, 2012.
