I need a working prototype of a fully-automated roti-making machine that can turn out 100 soft, evenly cooked rotis in 30 minutes while keeping the total build cost under ₹10,000. Durability is my top priority: gears, belts, heating plates, and the overall frame must stand up to continuous use without needing frequent maintenance. Heating flexibility is also essential. The design has to accept both induction coils and standard gas burners so I can switch energy sources as required. From dough portioning and pressing to cooking, puffing, and neatly stacking, every step should run hands-free once ingredients are loaded. To keep the budget realistic, I’m open to clever use of off-the-shelf components, 3-D-printed parts, recycled food-grade stainless, or low-cost electronics such as Arduino or Raspberry Pi for control and sensor feedback. Just make sure anything in contact with the dough is food safe, easy to clean, and remains rigid over time. Deliverables I expect: • CAD drawings with assembly instructions • A complete bill of materials showing per-item cost and total staying below ₹10,000 • Control schematics and firmware source code • A short demonstration video of the prototype producing 100 rotis in the stated time • Post-prototype notes highlighting durability tests and any recommended improvements If you already have experience with compact food machines, induction heating, or budget-conscious automation, your insight will be invaluable. Let me know the tools or methodologies you intend to use and the timeline you need to ship or demo the prototype.

Sir, I am a perfect fit for your requirement. I have already completed similar automation and mechanical design projects and bring 17 years of experience in product development and machine design. I can design a durable, cost-effective roti-making prototype with CAD, BOM, control schematics, Arduino/Raspberry Pi integration, food-safe components, and complete assembly documentation while focusing on reliability, manufacturability, and easy maintenance. Before proceeding, may I ask whether the ₹10,000 budget includes fabrication and electronics or only material costs? Also, is the target of 100 rotis in 30 minutes expected to be validated on a single prototype or is a proof-of-concept demonstration acceptable initially? It would be my pleasure if you give me the opportunity to show my capabilities. Thank you for your valuable time and consideration.

Hi, I can help design and prototype your low-cost automated roti-making machine with CAD drawings, BOM, control schematics, Arduino/Raspberry Pi logic, and a practical build plan focused on durability and food-safe operation. The best solution is to first break the machine into clear modules: dough portioning, pressing, heating/cooking, puffing, stacking, frame structure, drive mechanism, and control electronics. Then I’ll design a cost-optimized prototype using off-the-shelf motors, gears/belts, food-safe contact materials, simple sensors, and a controller-based sequence that can support gas or induction heating. I’m comfortable with mechanical design, compact food-machine concepts, Arduino/Raspberry Pi control, automation, CAD modeling, low-cost prototyping, motor/relay control, heating integration, BOM planning, and assembly documentation. Deliverables will include: * CAD drawings * Assembly instructions * Low-cost BOM * Control schematic * Firmware source code * Dough pressing/cooking workflow * Gas/induction heating concept * Prototype testing notes * Improvement recommendations * Demo support plan I’ll focus on a realistic, durable, and budget-conscious prototype approach, clearly identifying what can be achieved within the ₹10,000 build-cost target and where stronger components may improve long-term reliability. Best regards Ankit

Give me one opportunity to handle your project. I have strong experience in mechanical design, automation, Arduino-based control systems, and CAD development, and I can design a cost-effective prototype with a focus on durability, food safety, and ease of maintenance. I will develop the complete CAD assembly, detailed manufacturing drawings, BOM with cost optimization, control schematics, firmware, and assembly documentation. The machine will be designed to automate dough portioning, pressing, cooking, puffing, and stacking while supporting both induction and gas heating options. Components will be selected from reliable off-the-shelf parts, food-grade stainless steel, and suitable 3D-printed parts where practical to minimize cost without compromising reliability. Before fabrication, I will validate the design for manufacturability and continuous operation, followed by prototype testing and performance improvements. I will also provide a demonstration video, source files, and recommendations for future production-ready enhancements. I am committed to delivering a high-quality solution on time with clear communication throughout the project. I look forward to working with you.

Hi, This is the kind of project where **mechanical design, thermal control, automation, and “why is the roti stuck to the roller?” engineering** all meet in one machine. ? I can develop the prototype around a modular workflow: **Dough portioning → pressing → transfer → dual-stage cooking/puffing → stacking** My approach would use: • Food-grade SS contact surfaces • Arduino/ESP32-based control and sensor feedback • Geared motors + durable belt/chain transmission • Adjustable press geometry for consistent thickness • Temperature sensing and closed-loop heating control • Modular heating section compatible with gas and induction concepts • CAD designed for easy fabrication, cleaning, and maintenance The key engineering challenge is achieving **100 rotis/30 min (~18 sec per roti)** while staying near ₹10,000, so I’d optimize around parallel cooking stages and locally available components rather than expensive custom hardware. Deliverables can include CAD, BOM, wiring/control schematics, firmware, assembly notes, prototype testing, and performance/durability observations. My goal: a machine that makes rotis—not an expensive robotic sculpture that makes one roti and then asks for maintenance. ? Best, Mohamed Amine

I've built automated food processing prototypes before and can deliver the full stack here: Arduino-based control firmware for dough portioning, heating plate cycling, and stack management, plus dual-mode heating logic to switch between induction and gas burner sensors seamlessly. I'll create detailed CAD assemblies in Fusion 360 showing modular stainless steel pressing and cooking chambers, design the complete BOM with verified low-cost suppliers in India, and program the controller with feedback loops for temperature and timing. The demo video will show real-time production hitting your 100 rotis in 30 minutes target. Durability testing notes will cover gear wear patterns, belt tensioning, and thermal cycling stress on budget components.
