• Designing and building a robot capable of copying the gait of a caterpillar

• Capable of giving its position and state feedback

• Microcontroller Arduino, Joystick module, DC motors, L298 motor driver

• Used rubber cords as tendon material to give smooth expanding

• The body material used is foam to increase flexibility 

• Project is under Professor Barry Trimmer Biology, Assistant Professor Neuroscience Graduate Biomedical Sciences Member, Neuroscience Program Henry Bromfield Pearson Professor of Natural Science, Biology Professor Biomedical Engineering

• Used OpenCV  for hand gesture recognition using Python and Arduino IDE to control Servo motors of the fingers 

• Used serial connection to send commands from Python script to Arduino IDE

• Used Items: Microcontroller Arduino, SG-90 servo motors, Battery 

• Used an ESP-32 camera module to recognize hand gestures to start and stop the main motor and a microcontroller also a lidar to detect if any person is in near proximity of 100 mm to the machine which then caused it to stop. For the camera module, we used an open cv library available online. 

• 3-D printed the whole base the bubble-making ring and the solution tank. 

• the aim of the project was to have some sort of human-robot interaction which we were able to accomplish 

• My project partner was Micheala Freed

This was the most difficult assignment that I faced here at Tufts since designing and developing the product both had the same weightage 

• Used an ESP-32 as brain. an IMU (wit motion) to fetch in a change in acceleration,  degree of change in the direction to PID control inside the program, Lidar for detecting any surface in front of proximity less than 50 m  

• Used aluminum frame for the robot body and customized 3-D print for holding the battery, sensors, buck convertor, and under voltage cutter.

• Design and developed a 3 degree of freedom robotic arm

• 3 SG-90 servo motors and ESP-32 microcontroller 

• 3-D printed the arms or links 

• Goal was to write name initials

• Goal was to make an analog clock from a microcontroller and use servos 

• I laser cut wood of thickness 6 mm to make the base and dials for an hour, minutes, and seconds for the clock 

• used an ESP-32 microcontroller and using an NTP server connected to WIFI and time zone which enabled the clock to set its time on its own as soon as it is started

• Goal of this project was to know a robot's status while it's in its job using a QR code pointed towards a user's mobile having a specific App

• My work was to design a fake experiment where the turtle bot was supposed to move within certain checkpoints and every time it stops at a checkpoint the user can scan the code on its tab or mobile and an Emoji image pop up on the app telling the status of the robot and its task

• worked on ROS and gazebo to fake the simulation

• also got to learn about SQL query databases and AR

• Designed and devloped a burger flipper that is capable of flipping a burger patty by a person who can use only one hand

• No electronics were involved in the design only 3-D printed the gears and the body 

• the blue color dial is used to rotate the flipper blade once its beneath the patty by just using the thumb and rotating it clock wise

• Designed and manufactured a smart baby stroller to easily attach  and detach from a wheelchair

• Features like a Linear actuator to lift and collapse the baby seat

• Turntable  top to rotate the baby seat for easy reach accessibility

•  Camera at the front providing a live front view on the user's mobile while in motion

• Designed the discharge, return, and pump house for a 300 TR forced draft Cooling tower at my previous company 

• Also designed the civil part for the water sump to store water after cooling from the cooling tower

• discharge was divided into 2 sizes 6", and 8" for chillers and pet blowing machines respectively

• Goal was to design and develop  a monorail that could sustain at least 1000 kg of load while moving that object over a span of 20 meters

• I designed and implemented the erection work of the monorail  to 1500 kg capacity to pick up the load

• Used a 250 MM I beam as the monorail and ordered a Hoist from the market with 2 wheels made up of material suitable to work on the caste Iron flange of the I beam

• Due to covid and the sudden breakdown of the machines I had to re-design a 200 ML Pet bottle sleeve machine to a 2000 ML sleeve machine 

• Parameters of the delay time of sensors, motor speeds, and other Inputs and outputs were re-structured to get the machine to work

• Experienced in working on Allen Bradly, Omron, and Shnider VFDs

• saved the cost of 2 labors to handle the hydraulic lifters to operate and no. of workers reduced due to the efficiency of the product and increased storage area.
