Pulled by the fascinating and broadly useful field of mechatronics, I decided to get some hands on experience making robots. The video here shows the bot our 4 member team made in two and half weeks, as part of the amazing ME 210 course at Stanford. We implemented tape sensing, IR beacon sensing, a robust token delivery and drivetrain. By dropping poker chips in each of the 5 bins, we completed the objective of tilting all seesaws towards our side. I thoroughly enjoyed the process and would like to implement what I learnt in the future.
Fabrication Engineering (semiconductors)
We completed the device fabrication strategy for 3D Vertical NAND Flash Memory optimizing for the best set of process steps among various lithography, etching and deposition techniques learnt in the fabrication engineering course. I also learnt about the application, implementation and advantages and disadvantages of many of these techniques making me proficient in the knowledge of these techniques.
As a 2 member project, we designed and fabricated an I beam made of 13 layers of composite material. This beam was then tested for failure load and we predicted failure load using appropriate Tsai-Wu and progressive ply failure criteria using MATLAB.
As part of the manufacturing techniques course at BITS Pilani, we constructed the swashplate of a helicopter mostly using material from the junkyard. Completing a complex design, gave us exposure to most of the techniques that were used in the workshop.
Other manufacturing and design projects
- Wheelchair with detachable walker - Completed a new concept wheelchair with a detachable walker, requiring no extra space, making available both wheelchair and walker as per use for the disabled
- Energy conversion using wood densification system - Fabricated a pellet making machine to compress wooden powder into pellets. Also designed a stove in connection with it to maximize energy that can be extracted from wood
- Rotating and revolving fan - A fan that relvolves around a secondary axis in addition to rotating about its own axis. The aim being to maximize area covered with similar energy requirement.
- Easy wheel locking design - After changing tires of my car for the first time, i felt the need for making the process easier. So i designed a lock with a design similar to a lathe hub that would need just a key to remove or attach the wheel.
