Get Ready to Buy Pedro Robot – Launching Soon!
Pedro is a compact and customizable mini robotic arm entirely 3D printed, specifically designed for STEM projects. Equipped with four mini servo motors and powered by a custom-made Arduino-compatible board, Pedro offers versatile wireless communication options with its integrated nRF24L01 module for remote control, HC-05 Bluetooth module for smartphone connectivity, and ESP8266 WiFi module for IoT integration. It also features an OLED 128x64 display, allowing real-time feedback and data visualization.
To ensure smooth and accurate operations, Pedro is equipped with
8000
two ball bearings, strategically placed for enhanced precision in its movements. This versatile and educational robot is perfect for hobbyists, students, and makers looking to explore robotics, electronics, and programming, all while enjoying a hands-on and engaging experience.
In Feburary 2025, Pedro Robot has been certified as open-source hardware by the Open Source Hardware Association under UID: FR000025.
In March 2025, Pedro was successfully funded on Kickstarter at 268% of its goal, receiving incredible support from backers around the world.
🙏 A huge thank you to all our backers for believing in the project!
Pedro is powered by an integrated ATmega32u4 microcontroller, making it easily programmable using the Arduino environment ideal for learning robotics and coding. All of its components are designed to be 3D printed, and the robot can be assembled without any tools, offering a hands-on and accessible experience for users of all levels.
- 4 Mini Servo Motors: For precise movements.
- Arduino-Compatible Board: Designed specifically for this project, offering easy integration with the robot's components.
- 7.4V Batteries: Powering the robot, rechargeable via USB.
- Fully 3D Printable: All structural components can be printed on a standard 3D printer.
- Tool-Free Assembly: Designed to snap together easily without the need for tools.
- Micro USB Cable: Enables charging, firmware uploads, and serial data exchange with the control application.
The Pedro Board is here to revolutionize how you learn and create in electronics, programming, and robotics. Designed with simplicity and versatility in mind, this open-source board comes in two versions:
- Rev2 with 2 integrated modules: NRF24L01 and OLED 128x64.
- Rev3 with 4 integrated modules: Rev2 modules + ESP8266-01 and HC-05
Both versions offer a compact and efficient design to help you bring your Pedro Robot to life!
Additionally, the Gerber files for the Pedro Rev 2 are available for those who want to create their own custom Pedro robot board.
- OLED Screen (128x64): Visualize data, debug in real-time, or create interactive menus.
- NRF24L01: Enable long-range wireless communication between Pedro or devices.
- ESP8266-01 WiFi Module: Bring your Pedro online with ease. (Rev3 only)
- HC-05 Bluetooth Module: Connect wirelessly to smartphones or other devices. (Rev3 only)
Pedro Robot App is a desktop application built with Python and Tkinter that allows you to control the Pedro robot via a USB serial connection. It provides a simple GUI to select servos, move them interactively, and manage serial communication with the robot.
- Prerequisites
Before running the application, make sure the following Python packages are installed:
pip install pyserial pillow
tkinter is usually included by default with Python (on Windows/Linux). On some Linux systems, you may need to install it via your package manager:
sudo apt install python3-tk
-
Required Python Libraries:
- tkinter — GUI framework (built-in)
- serial (pyserial) — for serial communication
- Pillow — for image loading and display
-
Robot Firmware Requirement:
This application requires the corresponding Arduino code to be uploaded to the Pedro robot board. Required Sketch: serialMode.ino Communication: Serial (baudrate 9600)
-
Key Features:
- Serial port selection and connection management
- Real-time servo control through a clean interface
- Visual feedback for connection status
- Compatible with Arduino-based firmware
