Design & Analysis

Quick links:

Design:

Software’s used: Fusion360, AutoCAD, SolidWorks

Robotic Arm:

Designed a robotic arm in Fusion360 and then carried out inverse kinematics in MATLAB to find Joint angles and Jacobian matrix to find get a motion profile for the arm to move to the specified position.

Self-balancing bot:

Simulated the motion of two-wheel bot using PID control loop on MATLAB.

WiFi based Voice enabled Mood-lamp:

This mood lamp emits soft colours to uplift ones mood when triggered using voice commands or by using a mobile application.

Pizza Cutter Redesign:

Most of the pizza cutters available in the market have exposed circular blades. These are not only difficult to store but are also dangerous if left unguarded on the kitchen platform.

Solution to this issue would be to design a protector case for the blade. But having two detachable parts might be a good but caps and cases are more prone to be misplaced (especially, for objects that are often used). That is why I designed a Circular Pizza Cutter with an attached protector case.

Other designs:

Compliant mechanism (Clippers)

Posture Corrector

Double pendulum: Chaotic movement

Simulated the chaotic motion of a double pendulum using MATLAB.

Analysis:

Analysis of Bolted nozzle flange of Saturn V:

The Saturn V’s first stage was powered by five F1 engines. Analyzed the bolted flange joint that connected the mid and lower parts of the F1 engine nozzle. The image below shows a picture of the F1 engine and the corresponding model in ANSYS.

Analyze this bolted joint by building a non-linear finite element model in ANSYS. The main objective was to assess the margin of safety of the flange bolts and to determine the gaps that develop between the jointed parts when the assembly is loaded.
