I’m building a one-off electromechanical rig for a video shoot and need an engineer who can turn my early concept into a fully documented, composite-cased prototype. The system ties together small motors, a microcontroller board, camera modules, a handful of sensors, and a rechargeable battery pack. THE DESIGN HAS ALREADY BEEN MADE BY ANOTHER INDIVIDUAL, you just need to re-create it. I have a video documenting how it was made as reference: [login to view URL] Electronics and firmware are already detailed. Here’s what I need from you: • Refined system architecture with final component selection • 3D CAD of all custom parts plus the complete assembly in a common format (STEP preferred) • Structural analysis or reasoning to justify the chosen composite lay-ups/thicknesses • Detailed wiring and electronics diagrams that align with the mechanical layout • Well-commented firmware ready to run on the selected microcontroller • A full BOM with supplier links and part numbers • Assembly and functional test instructions so I can reproduce the build in my workshop Real-world experience taking electromechanical products from concept to functioning prototype is essential. When you reply, link to past work that showcases relevant robotics, embedded electronics, or mechatronics projects—working videos or photos are ideal. I’m ready to begin as soon as I find the right partner and will stay responsive throughout the design, review, and iteration cycles.

Hi, I am an embedded systems engineer with over 16 years of experience developing complete consumer-grade electromechanical products from concept through functional prototype and production documentation. I have extensive experience with mechatronics, motor and sensor integration, microcontroller systems, composite enclosures, 3D CAD, structural validation, wiring documentation, firmware, and prototype testing. I can study the reference video and recreate the existing design as a fully documented, workshop-buildable system. I will refine the architecture and component choices, produce STEP models for every custom part and the full assembly, justify the composite lay-up and thicknesses, align the wiring diagrams with the mechanical design, prepare clean firmware based on the existing electronics details, and provide a supplier-linked BOM plus clear assembly and test procedures. I can also support design reviews and practical adjustments as the physical build progresses. My relevant project photos and working videos cannot be shared publicly, but I can show selected examples privately. Do you have approximate dimensions, target payloads, and any original component list or CAD files in addition to the video? Please contact me to discuss details.

Hello, This is not an AI bid; this is a self response. Your concept is already documented, so I can focus on accurately recreating the electromechanical rig as a workshop-ready prototype package rather than reinventing the design. I will translate the reference video and existing electronics details into clean 3D CAD, a complete STEP assembly, composite casing documentation, aligned wiring diagrams, commented microcontroller firmware, and a supplier-linked BOM with clear assembly and functional test instructions. I will coordinate the mechanical layout carefully around the motors, camera modules, sensors, battery, and controller so the final files are practical to fabricate and assemble. I can also structure the documentation for straightforward review and iteration as the build develops. Once you share the original electronics/firmware files and any available dimensions, I can begin recreating the assembly and provide an initial CAD review milestone promptly. Should the recreation match the video’s dimensions exactly, or may I improve clearances and service access while keeping the same function? Best regards, Sahil

I understand you need a precise CAD recreation of an existing electromechanical rig, similar to the documented prototype in the provided video. My experience with translating physical prototypes into robust digital models ensures accuracy and attention to detail for your composite-cased system. I will use SolidWorks to meticulously model each component, referencing the provided video and any available schematics. The process will involve detailed component breakdown, precise dimensioning, assembly creation, and final drawing generation for manufacturing, focusing on ensuring all integrated elements (motors, microcontroller, cameras, sensors, battery) are accurately represented and positioned. Does the existing design have any specific tolerances or material considerations that are critical for the composite casing? I'm ready to dive into the details and would be happy to discuss the project further to ensure a seamless CAD recreation.

Hello, I reviewed the requirements, and the core challenge is accurately recreating the existing electromechanical design while ensuring the CAD assembly, composite casing, wiring, electronics, firmware, and BOM remain fully aligned. I have worked on similar mechatronics and prototype development projects involving 3D CAD assemblies, embedded electronics, wiring documentation, component integration, and production ready technical documentation. The supplied build video and existing electronics documentation can be used as the reference while rebuilding the complete system into a structured, reproducible prototype package. Also a quick question, does the reference video show the complete internal mechanical arrangement and component mounting, or are additional reference images available for areas not visible in the video?

I can handle the mechanical/CAD side of your electromechanical prototype and recreate the existing design from the provided video and references. I can model the custom composite casing, component mounts, brackets and other mechanical parts in Fusion 360, then build the complete assembly with accurate component placement, clearances and practical fastening details. I can provide the native CAD files and STEP assembly for fabrication. I can also document the mechanical layout and provide practical guidance on mounting, enclosure thickness and assembly. For the electronics firmware, detailed circuit design and embedded programming, I would prefer those to remain with the existing electronics/firmware specifications rather than overclaiming expertise outside my primary CAD work. If the mechanical portion can be handled separately, I’m ready to start immediately.

The video shows a hand-built rig and you need that design re-created and documented in CAD, specifically with a composite casing. I’ll start by using the video to build the basic structure in Solidworks, then I’ll integrate your documented electronics and motor specs. For the composite casing, I would use Solidworks to model the shell and then create the necessary data for manufacturing, assuming a multi-piece mould design for simplicity. I’ll also perform basic stress analysis on key structural elements to confirm the composite will hold up. This brief doesn’t specify the exact composite material and thickness for the casing. I’ll proceed assuming a standard fiberglass lay-up with a 2mm thickness until you advise otherwise. My 10 reviews on Freelancer are all 5.0, everything delivered on time and on the agreed price so far. What specific mounting requirements do the camera modules have for optimal positioning in the video shoot? I’ll finish the 3D CAD assembly and the initial composite casing design within the first day or two.
