Assembly & Simulation
Gripper design, assembly and simulation
Designing a gripper was a rewarding experience. As a beginner, I faced challenges but learned a lot about Fusion 360. The process of creating each component and seeing them come together was truly satisfying.
Design Process: Sketching > modeling > assembly > Simulation > material

Assembly: Constraints > joints > motion study > Rotations > rigid bodies
Generative Design
Generative design is a computer-aided design (CAD) technique that uses artificial intelligence to create optimal designs for a product. The ability to explore various design possibilities and witness the software generate innovative solutions was amazing.
It automatically delivers solutions based on your constraints and requirements, including materials and manufacturing processes.
Improve engineering productivity and time-to-market with rapid exploration of innovative CAD models. as generative design will help challenge assumptions and deliver high-quality, lower-cost, manufacturable solutions.
I have generated a six-wheel robot with the help generative design for weight and strength.

Animation and rendering
Lego structure in Fusion 360
This is one of the more interesting task for me , This task involved designing a Lego structure in Fusion 360 and animating it using motion studies. A Lego man was created and placed on a busy street with a cobblestone texture. A sunset effect was achieved using lighting and color gradients. Soviet-era tanks were added to the background for a historical setting.

i have designed a voltage multiplier in TinkerCad with the help of given YouTube referral link,
short-circuit protection circuit
Logic design
full adder using 2x1 Multiplexers
here i have leant about the multiplexers, and designing logic.Usually a multiplexer takes one or more inputs and gives a single output , Here i have used 2x1 multiplexer which takes 2 inputs and gives one output
Filter Design
it was bit challenging task for me designing second order band pass filter using IC741 that amplifies the signal to roughly 1.5 times the original signal with the help of LTspice software. here is the circuit diagram and output graph.
