Greetings! My name is Shadab, a seasoned full-stack developer who passionately blends extensive hardware engineering knowledge with software development expertise. In previous projects, we have incorporated elements of AI, Machine Learning and IoT into web and mobile applications. This aligns perfectly with your groundbreaking prototype — an AI-powered automated home cooking machine. With profound skills in Arduino, Electrical Engineering, Electronics, Machine Learning (ML), Microcontroller, PCB Layout, and specifically Raspberry Pi, we foster a deep understanding of your project needs and protocols such as serial/UART. Our experience in deploying robotics arms in various motions like stirring and ingredient-pushing will ensure precise yet smooth functioning of your 4 to 5 DOF servo-motor-based robotic arm. Not only do we have the technical capacity to expertly build each of the 5 subsystems you require but also we possess a unique blend of creativity and precision. This mix is essential for developing proper PID temperature control loops that guarantee maintaining set temperature within ±5°C for optimal cooking. Plus, as skilled web developers specializing in Django, Flask, Express among other frameworks -- the task to create a user-friendly mobile app or touchscreen UI is truly up our alley. Together, let's not only turn your ambitious concept into a reality but also redefine home cooking experiences.

Hi, AI-powered cooking machine with robotic arm, stepper-driven hoppers, PID heat control, and RPi+Arduino dual-brain — ambitious and well-scoped brief. I can cover the embedded hardware + firmware stack: — RPi ↔ Arduino UART bridge: RPi sends recipe commands (dispense X grams of Y, set temp Z°C, execute stir sequence); Arduino executes in real-time and sends sensor feedback back — Stepper + HX711 load cell per hopper: dispense-by-weight loop — run stepper, read load cell at 10Hz, stop when within ±2g of target. Tare on startup, drift compensation after each dispense — Thermocouple (MAX31855 + Type-K) feeding Arduino PID loop for induction cooktop relay/PWM control — ±5°C target is achievable with tuned Kp/Ki/Kd — 4–5 DOF servo arm: pre-programmed motion sequences (stir, push, rest) stored as waypoint arrays, executed on recipe trigger — no real-time IK needed at PoC stage — Simple Flask + React touchscreen UI on RPi for recipe select, start/stop, live temp + dispense status Honest note on budget: the component BOM alone for this system (steppers, load cells, servos, induction hob, RPi, thermocouple, drivers, frame) will likely exceed the listed budget. Happy to discuss a phased approach — starting with the control electronics + firmware as Phase 1, mechanical assembly as Phase 2. Can we set up a quick call to align on scope and realistic budget?

Hi, I'm a Mechatronics Engineer with hands-on experience building robotic prototypes involving multi-DOF servo arms, stepper-driven dispensing systems, and embedded control architectures — exactly what your cooking machine requires. Here's why I'm the right fit: Computing Brain — I've built Raspberry Pi + Arduino dual-layer systems with serial/UART comms for real-time motor control alongside high-level recipe logic. This is my bread and butter. Ingredient Dispensing — I've designed hopper systems using NEMA17 steppers with HX711 load cell feedback achieving ±1–2g accuracy. I'll deliver 4+ hoppers (dry & liquid) with closed-loop weight control. Robotic Arm — I'll build a 4–5 DOF servo arm with pre-programmed motion paths (stirring, pushing, pan interaction) using inverse kinematics for smooth, repeatable trajectories. Heat Control — PID loop on Arduino reading K-type thermocouple via MAX6675, controlling induction cooktop relay/SSR to hold ±5°C. Done this in industrial heating projects. Control Interface — I'll deliver a clean Flutter-based mobile app or RPi touchscreen UI for recipe selection, start/stop, and live telemetry (temp + dispensing status). My approach: 2-week sprints — Subsystem 1–2 (week 1–2), Arm + Heat (week 3–4), Integration + UI (week 5–6). Weekly video demos so you see real progress. I'd love to discuss your timeline and demo recipe scope. Happy to hop on a quick call.

I’m very interested in helping build your AI-powered automated cooking prototype. While I’m new to Freelancer, I have extensive hands-on experience in mechatronics, robotics, and embedded systems development. I can develop all five subsystems you outlined. Computing Brain with a dual-layer Raspberry Pi and Arduino setup with reliable serial/UART communication. Ingredient Dispensing Unit with multiple hoppers using stepper motors and load-cell feedback to achieve ±2 g accuracy. Robotic Arm with 4 to 5 degrees of freedom using servo motors capable of stirring, ingredient pushing, and pan interaction with pre-programmed motion paths. Heat Control system integrating an induction cooktop with PID temperature loop and thermocouple feedback to maintain ±5 °C. Control Interface through a mobile app or touchscreen UI showing recipe selection, live temperature, and dispensing status. I am based in Delhi NCR and can work directly in your lab with your equipment for faster prototyping and testing. My focus is on functional, testable demos that meet strict accuracy and reliability requirements. Ready to start immediately and deliver a fully working demo unit for your proof-of-concept stage. Best regards.

Hi, I have strong experience in embedded systems, robotics, and mechatronics, including Arduino and Raspberry Pi based control architectures. I can design and develop your proof-of-concept cooking machine by integrating all required subsystems efficiently. I have worked with stepper motors, load cells, PID temperature control, and multi-DOF robotic mechanisms. I can implement reliable UART communication between Raspberry Pi (high-level control) and Arduino (real-time execution), ensuring smooth coordination across dispensing, motion, and heating systems. For your system, I will ensure: * Accurate ingredient dispensing using load cell feedback (±2g) * Stable PID-based temperature control with thermocouple input * Pre-programmed motion control for the robotic arm (stirring, dispensing, interaction) * Clean and modular firmware with proper documentation I am comfortable with rapid prototyping, iterative development, and working with lab-based setups. Looking forward to discussing your design and bringing this prototype to life. Best regards
