bexo V2.5
Active Back Exoskeletons for labor intensive workers.
A research project under EPIC Lab at Georgia Tech.
Lifting and loading tasks in the workplace are common sources of musculoskeletal injuries. Back Exoskeleton (Bexo) research team evaluates the performance of device during various manual tasks and how it might be integrated into workplaces to offset injuries.
bexo V3
Active Back Exoskeletons for labor intensive workers.
A research project under EPIC Lab at Georgia Tech.
While I think Bexo V2.5 is a really great active back exoskeleton design (not bias at all 😌). It still has a lot of room for improvements. One big thing is the weight of the device, limiting the comfortability of it. Nothing can be done much to improve this since the design is very much bare bone. Most of the weight comes from the two actuators (AK80-6). Therefore, I am exploring a new design overhaul that utilizes only one actuator!
Xspine
Patent Pending
Semi-rigid back exoskeleton
Xspine is proven to be an objectively better back exoskeleton design compared to Bexo. I went through a few iterations, and one of them has a patent pending! I urge you to learn more about this very interesting and unique piece of engineering.
Twister
Patent Pending
Pulley Tensioning system
This was one of the projects I did for Institute of Human and Machine Cognition (IHMC) Robotics during my Summer 2022 internship. It was super fun and challenging to work on this project and it turned out great! We decided to file a patent for it as well after I wrapped up the project. That being said, I will share just the surface level of the project to not interfere with the patent filing process.
NOWy.AI
A Machine learning project
The project is current in stealth mode right now, but I am super excited to share more about it when I can! 😉
VR GunStock
for Meta Quest 3
I wanted a fun project to work on during Thanksgiving break in 2023 and I recently got a Quest 3 headset at the time. So, I decided to design my own gunstock to play first-person shooter games with!
But design a basic magnetic gunstock would just be too basic and not as fun to design. So, I added a pump-action mechanism to it by adding a compliance mechanism.
Flowmodoro
for web embedding
I am sure many of you have heard of Pomodoro, but not Flowmodoro. I don’t think it is widely known, but it is basically a reversed Pomodoro. Instead of taking a break every 25 minutes, Flowmodoro lets you work for as long as you want then to take a certain amount of break (divide the work session time by 5 in this case) depending on how long you had worked. This allows for an uninterrupted work session which works a lot better for me since I don’t want to get interrupted during my “Flow” state.
Since this method is not wildly know, there is not a tool for me to use (a stop watch is an option, but not as cool, haha). I decided to create one, using HTML, JS, and CSS, for web embedding since I want to use it on my Notion!
I have a plan to turn this into a physical device in a keychain form to make it portable and just to improve my electronics skill (stay tune! 😄)
Agrobot
Iot Vertical smart farm
The story behind this project is that I live in a condominium with very limited space. I wanted to cultivate my own produce while not spending a lot of time tending them. So, me in 2017 who recently learned about 3D printing and Internet of Things (IoT) decided to combine all three concepts together!
Born was the internet connected vertical smart farm or AgroBot! The plants will be planted in trays stacking on top of each other. the carrier with tool heads will move around precisely to each location to care for the plants. The functionalities include watering, liquid nutrients dispensing, and weeding
This is a simple IoT dashboard I created to monitor and control Agrobot. I could not find a picture of the dashboard that has a live camera feed.
I went around an entered competitions with this including a Makerthon (Hackathon for makers)! Of course, I won a lot of competitions with AgroBot 😋.
Line Tracking Robot
Robotic Car Racer
Here is where it all started... Back in 2016, I entered a robotics competition, competing to see whose robot would be the fastest! It was my first introduction to how amazing, fun, and exciting real engineering can be. It was also the first time I learned about PID controller! The video you see is the final round of the race. It may not seem that fast, which it wasn’t, but considering the knowledge I had at the time, I am pretty proud of my younger self! (Plus, I won the competition, haha.)
B150
Budget 3d printer
Back in 2017, I got my first ever 3D printer, Tevo Tarantula. An era before the birth of Ender 3, haha. I had so much fun (and pain) trying to assemble that printer, but I learned so much during the process.
Fast forward a year, I wanted to really learn how to design such a machine of my own. As a broke high school student, I had to keep it under a certain budget which was around $175. That price was amazing back then.
I wiped up Fusion 360 and started designing it. Most parts are 3D printed using the printer I had. B150 turned out great! It has 150 x 150 x 150 mm print volume. Looking back at it, the design was nowhere near perfect. There were a bunch of stuff I could improve. However, I will cut myself some slack since I was just a beginner engineer back then!
