About Andino

Andino is an open ROS 2 differential-drive robot from Ekumen for education and low-cost applications. Its upstream repository includes a hardware README with linked components, printable chassis and camera-mount STL files, URDF description, micro-controller firmware, ros2_control hardware interface, SLAM, and Nav2 navigation stack around a Raspberry Pi 4 and Arduino Nano.

How to build Andino

5 steps

Steps marked Motari summary condense the linked source; follow the source for exact instructions.

  1. Print the chassis

    Print base_chassis, lidar_chassis, battery_chassis and arduino_lock_base from andino_hardware/printing_model/chassis, plus the two Raspberry Pi camera mount parts.

    Motari summarygithub.com/Ekumen-OS/andino/tree/main/andino_hardware

  2. Mount motors and sensors

    Install the two DG01D-E geared motors, caster wheel, BNO055 IMU and Raspberry Pi camera onto the base chassis per the assembly photos.

    Motari summarygithub.com/Ekumen-OS/andino/tree/main/andino_hardware

  3. Wire the electronics

    Connect the motors to the L298N driver and the Arduino Nano, then to the Raspberry Pi 4. Follow the motor/Arduino connection diagram in andino_hardware.

    Motari summarygithub.com/Ekumen-OS/andino/tree/main/andino_hardware

  4. Flash the firmware

    Build and upload andino_firmware to the Arduino Nano with PlatformIO so it interfaces the low-level motor and encoder hardware with the SBC.

    Motari summarygithub.com/Ekumen-OS/andino/tree/main/andino_hardware

  5. Bring up ROS 2

    Build the colcon workspace on the Pi, launch andino_bringup, then run SLAM and Nav2 for autonomous navigation.

Builds of Andino

0 reviewed

No reviewed builds of Andino yet.

A build log records the evidence (photos, a video, your repository), what the build cost, how long it took and what you changed. Each one is checked by Motari (until a maintainer claims this page) before it shows here, and reviewed builds count toward the reproducibility score.
