Scout Mk 1

This is Scout…an obstacle avoider that can log temperature and talk!

He can talk using a wave shield.The speaker used is rated 1/2W and 8 ohms.For the chassis I used a 4mm thick acrylic sheet (about 22cm X 20cm)…right now the chassis is only temporary as I plan to make a more robust one.

I used the TTS from here and saved the WAV files on to the SD card.

Some of his features are :

  • He can talk ( and make R2D2 sounds sometimes )
  • Avoids obstacles using the HCSR04 ultrasonic sensor.
  • Has an rgb led that glows blue when friendly and red when angry.
