Job Requirement – Precision Motor-Based Medical Device Development We are seeking a freelancer or product development expert to help bring a medical-related device from concept to working prototype. The device involves controlled, repetitive linear motion using a DC or servo motor, and requires a focus on safety, accuracy, and reliability. As this is a confidential project, full details will be shared only after signing a Non-Disclosure Agreement (NDA). What We Need: - End-to-end development support: idea to working prototype - Motor and component selection guidance - Custom PCB design and layout - Embedded firmware development (Arduino, ESP32, STM32) - Motor control logic with timing and safety features - Emergency stop and safety system integration - (Optional) Simple user interface (buttons, display) - Coordination with mechanical team or fabrication vendors Ideal Skills: - Embedded systems design (Arduino/ESP32/STM32) - PCB design with KiCAD, EasyEDA, or Altium - Experience with motor control (DC/servo/linear actuators) - Safety integration: limit switches, emergency cutoff - Prototyping and hardware debugging - Documentation: BOM, firmware notes, wiring, test checklist Nice to Have (Bonus): - Experience in healthcare, rehabilitation, or wellness products - Familiarity with motion profiling or compliance standards - Access to prototyping facilities or vendor network Deliverables Expected: - Guidance on component selection and sourcing - Custom PCB (schematic, layout, Gerber, BOM) - Functional prototype support - Firmware for precise motor control - Support for future upgrades Location: Remote acceptable. Preference for Mumbai-based candidates (or those willing to coordinate with local mechanical team). To Apply: - Share your portfolio (hardware + firmware projects) - Brief overview of your development process - Preferred microcontroller platform - Timeline and availability *Shortlisted applicants will be asked to sign an NDA before full concept is disclosed.*

With my extensive background in digital motor control, analog design, electronic design, PCB layout, and embedded systems, combined with proficiency in Arduino, STM32, and ESP32 platforms – I am well-equipped for your needs. My experience includes algorithms generation for motor controllers, low power distribution designs, RF transmitters and receivers, solar energy applications and PCB designs using Altium and other CAD tools that you've specified. My work portfolio demonstrates a range of projects involving similar requirements to those outlined in your brief. I have successfully developed 3-phased induction motor vector control drives for low speed usage, implemented motor drive systems including AC/DC converters and battery chargers. I am adept at circuit simulations using Orcad and Matlab – an asset that will come in handy during the development of your device. Being Mumbai-based myself or local mechanical team coordination is not an issue. More so because my past projects have encompassed precision motion control technologies using motors.

I have prior experience working with embedded systems (Arduino/ESP32), motor control, and hardware prototyping, including projects involving precise control, safety constraints, and real-world integration. For this project, I would approach development in a structured, milestone-based manner, starting from system design and component selection, followed by firmware and control logic, and finally prototype integration and testing. My focus would be on: Reliable motor control with timing precision Safety mechanisms (limit switches, emergency stop) Modular design for future upgrades Clear documentation (BOM, wiring, firmware notes) I’m comfortable working with ESP32/Arduino platforms, PCB tools like KiCAD/EasyEDA, and coordinating with mechanical teams if required. Given the scope, I suggest a phased development approach, which can be further refined after reviewing full requirements under NDA. Proposed Approach (Indicative): Phase 1 – Core System Design (~₹30K) Requirements breakdown Motor and component selection System architecture and safety design Control logic definition Phase 2 – Electronics & Firmware (~₹40K) PCB design (or dev-board based prototype) Firmware for motor control Safety system implementation (limit switches, emergency stop) Initial validation/testing Phase 3 – Prototype & Testing (~₹25K) Integration support Testing and iteration Documentation (BOM, wiring, firmware notes, test checklist)
