This is an educational robot intended to be used as a sniffer or line follower.
It has been designed to attach other components such as servos, LEDs, push buttons, a buzzer, and other sensors included in the product "Mi primer kit de robotica" ("My first robotics kit") distributed by bq.

BOM (see attached image)

Printed parts:

  • 1 x chassis
  • 1 x battery holder
  • 2 x wheel
  • 1 x sniffer


  • 15 x M3x10 screw
  • 2 x M3x40 screw
  • 16 x M3 nut
  • 2 x 3x50mm O-ring
  • 8 x AAA batteries

    Parts included in "Mi primer kit de robotica" by bq:

  • 1 x Freaduino UNO (Arduino UNO derivative)
  • 2 x IR sensors for line following
  • 2 x continous rotation servo
  • 1 x 8 AAA battery holder
  • 1 x Bluetooth Module (optional)

    Build Instructions

    See the attached pdf (in Spanish). Pictures are clear enough to follow the steps even if you do not understand Spanish.
    Check this video: https://www.youtube.com/watch?v=hQF05l-RxTo

    Example code

    Attached you will find a simple Arduino program for following a line ("Arduino_renacuajo_line_follow.ino").


    Now you can control your robot through the "RoboPad" app.
    So just upload the "Arduino_robopad_renacuajo.ino" into your robot, connect the Bluetooth Module and install the Android app:
