In this entry the DYOR Minion robot is presented. It is a robot that has been created in the Mobile Robotics class at UPV.

DYOR Minion

 

Components

The following components have been used:

  • Laser cut wooden parts in the shape of a minion
  • Arduino Nano v3.0
  •  I/O Extension Shield for Arduino Nano
  • Mini-USB cable (30cm)
  • Powerbank 3600mAh USB
  •  Micro servo FS90R (x2)
  • FS90R wheel (x2)
  • Micro servo SG90 (x2)
  • Crazy wheel
  • Ultrasonic sensor HC-SR04
  • Buzzer KY-006
  • LED Matrix 8×8 max7219
  • Line follower module TCRT500
  • SPP-C Bluetooth
  • DuPont cables (x2)

 

Mobile app

In order to control the robot via a mobile app, MIT App Inventor 2 has been used. The app has the following buttons:

 

  • Connect and Disconnect: connects or disconnects the remote Bluetooth control.
  • Buttons: when pressed, another screen with the 7 following buttons appears:
    • Four of them move the robot forwards, backwards, to the right and to the left showing different arrows in the matrix led.
    • The red one stops the robot.
    • The musical note allows the minion to dance and sing with random movements. The led matrix shows a musical note.
    • The exit button takes you back to the main screen.
  • Accelerometer: while it is pressed, the robot detects the movements of the phone and reproduces them (forward, backwards, right, left and stop).
  • Line: the minion starts to follow a given path while showing a star in the matrix leds.
  • Ostacles: the minion starts to move showing a smile in the matrix leds. When an object is detected, the minion turns its direction and shows a sad face.

 

Programming

Arduino has been used for the implementation of the code. Some of the parts have been developed with Facilino because of its easy and quick gerenation code.
