This project is a course project for the Universitat Autonoma de Barcelona's Robotics, Language and Learning subject I'm coursing on my Informatics Engineering graduate. I also made available the final sprint report with all the information needed to get this running :)

This is an Arduino-based stationary robot that scans for targets within a short radius and shoots projectiles. The project uses more than one Arduino boards connected through the I2C protocol to handle various tasks. I printed a case for the Arduino uno made by thingiverse user ZygmuntW. The code is hosted in my github repository link, along the instructions to set your own turret up :) The total cost of the project is around 90€ (this is including the approximate cost of the PLA I used to print the parts) depending where you get your parts, and around 40€ extra on top of that if you decide to get the neomatrix and 16 channel PWM I2C board from adafruit instead of a "clone".

The parts list is as follows:

  • Arduino Nano
  • Arduino UNO R3
  • HC-SR04 ultrasonic sensor
  • MG996 Servomotor (2x)
  • SG90 Servomotor (2x)
  • 8x8 WS2812B LED matrix
  • M3 x 10 screws
  • M3 x 15 screws
  • M3 nuts
  • M3 brass nuts (for embedding in the larger holes on the base)
  • M2 x 10 screws (to attach the servomotors to the arm, base and tray)
  • 5V power source capable of giving out more than 4A
