Title: Mechanical & Electrical Engineers Needed for Bionic Arm Project (CAD + PCB Design) Description: I am developing a bionic prosthetic arm project and I’m looking for engineers to help with both the mechanical design and electronics/PCB design. Roles Needed: 1. Mechanical Engineer - Experience with CAD software (Fusion 360 preferred but not required) - Design and improve a 3D-printable prosthetic hand/arm - Work with servo-driven mechanisms for finger movement - Ensure parts are strong, lightweight, and easy to assemble - Help optimize the design for 3D printing 2. Electrical Engineer - Experience with PCB design (KiCad, Altium, EasyEDA, or similar) - Design a custom PCB to control and integrate: - 11 servo motors - 5 EMG muscle sensors - 2 oximeter sensors to measure blood oxygen (SpO₂), heart rate, blood pressure, and body temperature - ESP32 or Arduino-based controller - Implement power management for a battery-powered system - Provide schematic, PCB layout, and BOM Project Details - The arm will use 5 EMG sensors to detect muscle activity and control movement - 11 servo motors will control the fingers and wrist - 2 oximeter sensors will be used to monitor SpO₂, heart rate, blood pressure, and body temperature - The controller will likely be ESP32 - The system should be compact and optimized for wearable robotics Timeline - Deadline: 2 days (3 days maximum) - The timeline for this project is very tight - Faster completion will be rewarded with higher pay - Engineers who can deliver high-quality work quickly will receive priority and potential bonus compensation Deliverables - CAD files for the mechanical design - PCB schematic and layout - Bill of Materials (BOM) - Basic documentation for assembly Preferred Experience - Robotics or prosthetics - Mechatronics systems - Servo motor control and embedded electronics Budget: Flexible and performance-based (faster delivery = higher pay).

Okay, I got what you want exactly. I am a Full Stack Engineer Embedded Engineer with 15 years of experience, providing PCB design, ESP32 embedded systems, servo motor control, and sensor integration for robotics devices. In my opinion, the key part of this project is building a compact control system that can manage multiple servos and EMG sensors reliably. The PCB must deliver stable power for the 11 servos while keeping clean signal acquisition from the EMG and biomedical sensors. This project is very similar to my previous works. I developed ESP32-based robotic control boards integrating multiple motors and sensor modules for embedded systems. I also designed custom PCBs and prepared schematic, layout, and BOM files for prototype manufacturing. One of the most important skills for this project is power management and multi-servo control in embedded systems. My approach focuses on stable power distribution, signal isolation for EMG sensors, and reliable MCU control architecture. ✅ So, I will divide your project into three major steps. 1️⃣ Design the PCB schematic integrating ESP32, EMG sensors, and servo drivers. 2️⃣ Create the PCB layout and power system for stable battery operation. 3️⃣ Deliver Gerbers, BOM, and documentation for manufacturing. Via private chatting or meeting, I will provide the creative idea and good tech solution for your project. Best regards.
