**Project Title:** ESP32 Based Educational Robotics PCB Design **Project Description:** I am looking for an experienced PCB designer to design an educational robotics development board. The board will be used for teaching robotics, IoT, and programming to students . The board should be based on an ESP32 module and must integrate multiple components and connectors so students can easily connect motors and sensors. The board should also be compatible with Scratch, so students can control the hardware using Scratch blocks. The freelancer should also create the required firmware or extension file needed to connect the hardware with Scratch. **Key Features Required:** 1. ESP32 module for WiFi and Bluetooth connectivity 2. Motor driver for 2 DC motors 3. Battery connector for rechargeable L...

Project Overview: We are developing a motor controller PCB for an educational differential-drive mobile robot used in university teaching and research. The board is based on a validated prototype with proven firmware, and we now need a production-quality PCB designed for manufacture and CE/UKCA certification. A detailed hardware specification document will be provided to the selected designer. This brief summarises the scope and complexity of the project. Board Function: The board controls two DC gearmotors with closed-loop velocity control, monitors battery voltage, manages safety systems (emergency stop, timeout, heartbeat), and communicates with a host computer or single-board computer over USB. It also provides regulated power to downstream devices via a USB-C Power Delivery source po...

We are seeking a highly skilled Mechatronics & Embedded Systems Engineer responsible for motor calibration, mechanical-electronic system integration, PCB quality enhancement, firmware optimization, and robust communication architecture development. The role demands strong cross-disciplinary expertise in electromechanical systems, embedded firmware, and wireless communication protocols. This position requires hands-on execution capability, system-level thinking, and ownership from prototyping to validation. --- Key Responsibilities 1. Motor Control & Calibration - Calibrate and tune BLDC motors (FOC / trapezoidal control). - Develop and optimize motor control algorithms. - Perform current sensing, torque tuning, PID optimization, and efficiency improvement. - Analyze motor performa...

Clean modular code (well structured, commented) ⸻ Hardware Being Used: • ESP32 Dev Board • L298N Motor Driver • 2 DC Motors • Ultrasonic Sensor (HC-SR04) • Servo Motor (for grabbing arm) • WiFi communication ...

We are looking for an engineer team which has a good PCB design skill and motor driver programming skill. This project is to upgrade our exhisting PCB(Old version→ prototype) to update version. We will make one prototype PCB to test. And we will break it down to two PCB for later (standard and downgrade version) This machine has the following system: 1 x main CPU (GD32F450IGH6) 1 x AC motor inverter (RS485) Command input 1x sensor Up to 5x stepping motor ( synchronized, need fast movement)　NCcode input/ Tool path input. Up to 5x sensor 1 x DC motor 1 x sensor 1 x SBC( RPI) need to connect to main CPU ( need to have fast communication ) 3 x stepping motor 3 x sensors 1 x DC brushless (small )-added 2 x stepping motor-added 3 x COM to other device. We will send the current prot...
