3-DOF spherical parallel mechanism
In this project, I explored and analyzed the design and functionality of a 3-DOF spherical parallel mechanism, specifically focusing on the Agile Eye. This mechanism, renowned for its high precision and speed, is designed to orient devices such as cameras with three degrees of freedom, replicating the motion of the human head. The Agile Eye features three symmetrical parallel mechanisms connected to an end-effector, which allows for swift and accurate orientation. The design optimizes performance by minimizing inertial mass and maximizing stiffness, enhancing dynamic capabilities. Additionally, I conducted a comprehensive analysis of the mechanism's kinematics, range of motion, and singularities, identifying operational challenges and potential improvements.
hovercraft
In this project, we have constructed a Hovercraft, which was able to glide on ground. The 3d model was designed in Solidworks and then simulation was done in ANSYS. It contained 2 set of propellers, one to generate the cushion of air to lift the hovercraft and other to provide thrust to move forward. Direction was controlled using two rudders.
all-terrain vehicle
The objective of this project was to design and develop a Roll cage for an All-Terrain Vehicle for SAE-BAJA competition. The design process started with the selection of material and tubing to be used. Then the chassis with frame was designed according to the rulebook of BAJA. The calculation was done to find the forces that act on the vehicle while various impacts and determined the strength required to sustain the collisions. A rigorous analysis of stress was done in ANSYS and checked for the failures. After finalizing the CAD model, the fabrication of Chassis started. The chassis was built as per the model and other components of vehicle then assemble to the body.
Quadrotor
For my thesis project, I designed and developed a Quadrotor, capable of flying, carrying a payload, and also doing surveillance work. I prepared the 3D model using SolidWorks, used the ANSYS for simulation, and optimized the design based on test results. Moreover, I prepared a dynamic model of the UAV to study its motion and then designed a control system to control the angular velocities, attitude, and altitude of the quadrotor to maintain a stable flight.
Airplane
We have designed and constructed a Radio Controlled Airplane. Extensive study was done to understand the concept of Aerodynamics and then each part of airplane was designed considering the desired performance. The modeling was done using Solidworks and airplane was constructed using Balsa Wood to keep it light weight. Wing design was optimized to provide maximum lift to drag ratio. The performance of airplane exceeded the desired performance.
airboat
In this project, we have constructed a boat that has propeller above the water and pushes air instead of water, thus known as Airboat. This design was unique as it can also be converted to run on ground with installing wheels to the base of Air Boat. Dual hull design was selected for the boat and high density thermocol was used to construct it. The HDT provides low weight to rigidity ratio. The rudder was constructed using balsa wood and helped to control the motion of boat.
