Assembly of DYOR MinionBot

By in , ensamblaje on .

In this entry, we show the assembly of DYOR MinionBot with TinkerCAD and make with laser cutting.

 

Components:

  • Arduino Nano + Shield Arduino Nano I/O (red)
  • Powerbank (pink)
  • Ultrasound HC-SR04 (grey)
  • Buzzer (black)
  • Servos SG90 (blue) in the frontal face
  • Servos FS90R (blue) in the base
  • Bluetooth (dark blue)
  • Linetracker TCRT5000 (dark blue)
  • Caster wheel (white)
  • FS90R wheels (black)
  • LED Matrix (green)

Instructions:

Glue both parts, the base and the frontal face.

Glue the FS90R servos to the base, the servo axis has to be as far as possible to the frontal face and screw the wheels to the servos.

Glue the caster wheel to the base.

Glue the TCRT5000 support just below at the feet and glue the TCRT5000 sensor to the support (glue it so the sensor is below the feet).

FS90R servo cables and TCRT5000 cables can be now pass through the base hole. After that, we can glue the LEDs matrix to the frontal face.

Connect the cables of the LEDs matrix to the top connector and glue the ultrasound sensor HC-SR04 (with the connector pointing upwards).

Glue to SG90 servos to the back of the frontal face and screw the horn to the servos (we should have previously check that the servos are in the mid position of 90º).

Glue the Powerbank, Arduino Shield+Arduino Nano, buzzer and Bluetooth to the robot’s base and connect the corresponding cables.

Finally, glue the arms to the servo horns and glue the bananas. Optionally, you can glue, too, the crown to the top of the head.
