Assembly of DYOR Standard

By in , ensamblaje on .

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

 

Components:

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

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 TCRT5000 sensor at the bottom part of the front trying to place it as far as possible to the front, to avoid collision with the cast wheel (later on).

Glue the SG90 servos with the axis as close as possible to the front. Screw the servo horns so that the mid position of 90º is as shown.

Glue the caster wheel below the base at the front part. Make sure that it freely turns and it is centred.

Pass the cables of servos and TCRT5000 through the hole at the base. Glue the LEDs matrix with the input connector pointing downwards.

Glue the buzzer.

Glue the ultrasound sensor HC-SR04 with the connector pointing upwards.

Glue the Arduino electronics, Powerbank and Bluetooth module to the robot base.

Finally, glue the LEGO parts corresponding to the grip to the servo SG90 horns.
