🔹 Core Positioning
This is an open-source programming education robot designed for makers, students, and electronics enthusiasts. Based on the Arduino jack, it integrates omnidirectional Mecanum wheel movement, PS2 controller remote control, Bluetooth control, robotic arm extension, and four-way line following capabilities. It is suitable for STEM education, robotics competitions, and project development.
🔹 Hardware Configuration
1. Main Control and Drivers
- Core Control Board: Arduino UNO R3 (compatible with Raspberry Pi and STM32 development)
- Motor Driver: L298N/L293D motor driver module, supporting independent control of 4 DC motors
- Power Management: LM2596 step-down module, providing stable 5V/3.3V power supply
2. Motion System
- Mecanum Wheels: 60mm omnidirectional wheels, supporting forward, backward, translation, and rotation in place.
- Drive Motor: 130TT geared motor (reduction ratio 1:48), providing ample torque.
- Optional Tires: Compatible with off-road rubber tires, replaceable according to the scenario.
3. Sensors and Expansion
- Line Following Module: Four-channel infrared tracking sensors, supporting black and white line tracking and obstacle avoidance.
- Obstacle Avoidance Module: HC-SR04 ultrasonic sensor, enabling automatic obstacle avoidance and distance measurement.
- Robotic Arm: Multi-DOF metal robotic arm (with SG90) Servo motors support grasping and handling actions.
- Reserved interfaces: Supports expansion with modules such as cameras, OLED displays, and buzzers.
🔹 Features
1. Multi-mode control
- PS2 controller remote control: 2.4G wireless connection, supports precise joystick control of the vehicle's movement and robotic arm actions.
- Bluetooth control: Remote control via a mobile app, real-time command transmission.
- Autonomous tracking: Four infrared sensors identify the path and automatically travel along a preset route.
- Obstacle avoidance mode: Ultrasonic sensors detect obstacles and automatically plan detours.
2. Omnidirectional mobility
- The unique roller design of the Mecanum wheels allows the vehicle to achieve lateral translation and 360° rotation in place without steering, suitable for operation in narrow spaces and complex trajectory movements.
3. Open Source and Extensible
- Provides complete Arduino open-source code and wiring diagrams, supporting graphical programming (such as Mixly) and advanced C language development.
- Modular design, supports stackable expansion, easily adding functions such as visual recognition and voice control.
🔹 Specifications
- Operating Voltage: 7.4V lithium battery (compatible with 3.7V-9V power supply)
- Motor Speed: 120rpm (no load)
- Remote Control Distance: PS2 controller approx. 10 meters, Bluetooth approx. 8 meters
- Robotic Arm Degrees of Freedom: 4 degrees of freedom (capable of grasping objects up to 50g)
- Body Dimensions: Approx. 19×10×18cm (including robotic arm)
- Applicable Scenarios: Teaching experiments, maker projects, robotics competitions
