IRIS Mechanism

2018

The iris mechanism, a fascinating design, moves a slide parallel to the angle's bisector while all of its blades move back and forth in a straight line to simulate the opening and closing of the eye.
The earliest version was made from stiff, flexible plastic sheets and cardboard. 12 leaflets make up the iris mechanism.
Although it may be beautiful, it does not run smoothly since it has a lot of blades and suffers from high friction caused by the blades overlapping. Therefore, I had to redesign it and change the number of blades, bringing it down to 5 blades, which worked without a hitch.

Dog Wheels

2018

Every year, more than 150k people die in road accidents in India, but the number of animals killed is far higher. In India, dogs are the most vulnerable and are frequently killed in road accidents. This initiative was created to assist dogs that have been in car accidents, were born paralyzed, or have any other limb problems. Because the market pricing for these things is relatively expensive, I created this project in an effort to stay below budget (4000 INR), for the NGOs in Guwahati that are rescuing dogs.

Robo Arm

2019

It is a 3DOF robotic arm that was created in Solidworks and manufactured using PLA plastic on a 3D printer. It possesses 4 servo motors (SG90). In the video, an Arduino mini and bluetooth module are used to control it. For path guiding, IR sensors are attached to the arm, which is installed in a 2WD kit. For powering the wheels, a motor driver circuit is coupled to a lithium-ion battery.
