Final project requirements
Final Project Wrap-Up
So here’s how I wrapped up my Fab Academy final project — my 15 kg battle bot. I’ve made a separate Final Project page on my site that documents everything: the design process, testing, code, files, videos, and even the rough patches I hit along the way, including weekly assignments. It’s basically a full behind-the-scenes of how this bot came to life.
Slide & Video
I created a clean 1920x1080 slide with the basics — my name, project name, lab name, and a render of the final bot. Nothing too flashy, just to the point.
For the video, I made a 1-minute clip that shows the bot in action — movement, wireless control, and the attack mechanism. I kept the audio raw because I honestly love the mechanical hums and clicks. Both the .png slide and .mp4 video are uploaded in the root directory and linked on my final project page. I tested them on phone and laptop . For now have uploaded bit of my work to check
What’s on the Final Project Page?
I made sure it covers all the essentials:
A quick summary of what the bot does and how it works
Approximate Bill of Materials (BOM) — not overkill, just what’s necessary to understand the build
Links to weeks where I worked on different components
A breakdown of how I integrated the whole system — mechanical, electrical, and code
All original design files — 2D, 3D, code, board designs — included in a downloadable archive
License info
Proper credit to any external help or references I used
Approximate BOM (Bill of Materials)
I didn’t go super market-mode for this list — it’s more of an honest breakdown of what went into the bot. Some components were from the lab, some bought online, and a few reused or hacked together.
| Item | Quantity | Source | Approx. Cost |
|---|---|---|---|
| ESP32 Dev Board | 1 | Lab Inventory | ₹300 |
| High-Torque DC Motors | 2 | Online | ₹2800 |
| 4S LiPo Battery (14.8V) | 1 | Online | ₹2200 |
| ESCs (Electronic Speed Controllers) | 2 | Lab Inventory | ₹1400 |
| CNC-Cut Aluminum Chassis | 1 | Fab Lab | ₹1000 |
| Polycarbonate Panels | Few pcs | Scrap/Lab | ₹500 |
| 3D Printed Mounts/Supports | Several | In-house | ₹250 |
| Motor Driver (if needed) | 1 | Online | ₹700 |
| Wireless Control (Blynk) | App-based | Free Version | ₹0 |
| Wiring, Screws, Connectors | Various | Lab Inventory | ₹600 |
| Total Estimate | – | ~₹9750 |
Some of the little stuff like zip ties, heat shrink, and nuts/bolts came from leftover lab materials, so I didn’t include every single thing here. The goal was to be practical, not precise down to the last washer.
What’s an ESC?
Just to explain — ESC stands for Electronic Speed Controller. It’s the component that sits between the microcontroller (in my case, the ESP32) and the motors. The ESP32 sends low-power control signals, and the ESC boosts that into high-power signals for the motors. Without ESCs, I couldn’t have fine control over speed or direction. They’re basically the brain-muscle translator for my bot’s movement.
System Integration
Making It All Work Together
This was the most challenging (and honestly, the most satisfying) part. I started by testing individual parts: motors with ESCs, wireless control through Blynk, basic movement. Once I was confident those worked, I started piecing everything together.
The frame was designed based on component placement — I made sure the battery and ESCs had good airflow and didn’t get cramped. I used the CNC to cut out the aluminum chassis, and 3D printed supports to mount parts securely. I even added a master switch for safety.
The code was written and uploaded on the ESP32 to receive wireless signals and control the motors via ESCs. There were a few glitches at first — like one wheel not responding or jerky turns — but after debugging the wiring and signal timing, everything started working smoothly.
The final round was about ensuring everything could run together without overheating, getting loose, or short-circuiting. After a few late nights and adjustments, it all clicked.
