# Request for Complete Micro-Robot Engineering Design & Manufacturing Files **Project:** Big Hero 6-Inspired Modular Micro-Robot **Maximum Total Budget:** KRW 500,000 (approximately USD 350–370, depending on exchange rates) Hello, I am looking for an experienced robotics, mechanical, and electronics engineer to design a fully functional miniature modular robot inspired by the microbots featured in the movie *Big Hero 6*. I am not looking for a concept design or visual 3D model only. I need a complete, manufacturable engineering package that can be sent directly to PCB manufacturers and mechanical fabrication companies. My goal is to manufacture **as many fully functional robots as possible within a total budget of KRW 500,000**, including engineering design, components, man...

Hello Yernaidu, Thank you for your proposal. I'm interested in working with you on my Big Hero 6-inspired modular micro-robot project. I would like to clarify exactly what is included in your **$30 quotation**. Does this price cover the complete engineering design package, including: 1. Complete mechanical CAD and 3D modeling (editable source files, STEP, STL, and manufacturing drawings). 2. PCB schematic and layout design, including Gerber files and BOM. 3. Two independently controlled robotic arms with adjustable angles and a target of 360° rotation. 4. Forward and backward movement mechanism. 5. Robot-to-robot docking and separation mechanisms. 6. Relative position detection between robots. 7. Bluetooth communication and microcontroller firmware. 8. Python-based PC software...

A compact double-layer board in one of my units has started to misbehave and, unfortunately, the original CAD files are long gone. I still have a clean schematic with every part ID called out, so the information is there—it just needs to be turned back into a full set of manufacturing data so I can isolate and fix the fault. Here’s what the assignment entails. I will provide high-resolution photos of both sides of the board together with the schematic. Trace the copper, match every net to the schematic, and rebuild the layout exactly as it sits today. Deliverables: • Editable schematic aligned with the physical board • Fault-analysis notes pointing to likely trouble at power input Freelancers are required to provide a budget estimate based on images supplied. Once ...

Complete Layout review of a 12 Layer PCB

I already have the full schematic for a two-LED flasher and now need it turned into a compact, production-ready PCB. Both LEDs will be mounted off-board, so instead of LED footprints I need two clearly labelled pairs of standard through-hole pads—four pads in total—to solder flying leads that run to the external diodes. The board should remain as small as you can reasonably push it while respecting clearance rules and hand-solderability. Please include a an on/off footprint on the PCB for a switch Mouser part # 633-MS13AFW01 Deliverables • Editable PCB design file (KiCad, Altium, Eagle or similar) • Gerber/NC drill set ready for fabrication • Simple BOM for all on-board parts • PDF plot or 3D view so I can check pad placement before we order boards...

Custom 3-PIR GSM Anti-Theft Security Alarm with SMS, Call & Relay PROJECT DESCRIPTION: I am looking for an experienced embedded hardware and firmware developer to design and develop a custom human motion / anti-theft security alarm using an ATmega328P (Arduino-compatible) microcontroller. The device will use 3 external PIR motion sensors connected to the main PCB through long cables. The main feature is a selectable PIR detection threshold of 1, 2, or 3 sensors. This will help reduce false alarms. MAIN PIR LOGIC: The device has: * PIR 1 * PIR 2 * PIR 3 The user can select the required number of PIR sensors that must detect movement. Threshold 1: Any one PIR becomes active = intrusion confirmed. Threshold 2: Any two PIRs become active = intrusion confirmed. PIR1+PIR2, PIR1+PIR3...

I need a thorough benchmarking study that centres on cost analysis for a range of existing electronic devices currently in the market. Price tags alone are not enough; I'm interested in breaking down total cost of ownership—component sourcing, manufacturing, licensing, maintenance, and disposal—so I can see precisely where each device’s money goes. Alongside the financial picture, I also want a clear view of reliability. Fail-rate trends, warranty return statistics, and any field-service data you can legally access will help me understand whether a cheaper unit truly holds up over time. Here’s how I picture the workflow: • Perform a teardown analyses or supplier quotations of devices available from me. • Normalise everything in a spreadsheet or da...

I’m a hardware design engineer working on designing a BLDC fan controller for my company. I’m looking for an experienced professional to guide me through the design, implementation, and validation process. Your role will involve: - Mentoring and providing feedback on my design and approach. - Assisting in creating a control algorithm focused on energy efficiency. - Reviewing selected MCUs or gate-driver ICs for compatibility with the project. - Offering advice on firmware best practices and PCB layout details. - Sharing insights from your experience (e.g., chipsets used, challenges overcome). The collaboration will help ensure an efficient, stable, and reliable BLDC fan controller design tailored for our requirements.

## Senior PCB / Electronics Engineer – Independent Final Review of Completed KiCad Board I am looking for an experienced electronics/PCB engineer to provide a **final independent second opinion** on a completed 4-layer PCB before I manufacture the first five assembled prototypes. **Budget: approximately £20–£30 fixed price.** This is **not a design-from-scratch job** and I am not expecting a lengthy formal engineering report for this budget. What I want is an experienced engineer to spend some focused time reviewing the completed design, identify any obvious or serious remaining risks, and tell me whether they would personally be comfortable sending the board for manufacture. ### Current status The board is **SP-MB1 Rev B.1** and has already undergone extensiv...

I need a complete electrical design for a true-online 600 W UPS that will operate in a home environment. The scope covers everything from the high-level architecture down to production-ready documentation, so that I can have the unit prototyped and assembled without further engineering work. What I expect you to produce includes: • Full schematic with clearly annotated component values • Bill of materials using readily available parts • PCB layout files (Gerber or equivalent) and 3-D board view • Control logic or firmware source (if a microcontroller or DSP is used) • Mechanical outline showing heat-sink placement, transformer or inductor dimensions, and suggested enclosure size • Brief test plan describing how to verify continuous 600 W output, transfer time...
