Introduction: Arduino 3D Printed Can Robot (one More Object Avoiding Robot)
In this "how to" guide I will show you how to make your own 3D printed Can Robot with the Arduino UNO micro-controller.
This is a remake of the Attiny Canbot that I found at Thingiverse.com by Wingman94 (link here) .
I made my own circuit with ATmega328 IC and I add a buzzer to make a beep tone every time that robot finds an object in front of it. I didn't include the IR remote control function.
This little robot is powered by one 3.7V 500mAh rechargeable battery and can be charged from the builtin charging circuit .
Watch my little robot in action:
Let's get started!
Step 1: What You Will Need - Hardware
For this project you will need:
- Atmega328 (with Arduino UNO bootloader)
- 28 dip socket
- 16 MHz crystal oscillator
- 2x22 pF capacitors
- 10 kOhm resistor
- 2 continuous rotation servo FS90R
- HC-SR04 ultrasonic sensor
- 3.7V 500mAh rechargeable battery
- Charging circuit
- On/Off micro switch
- PCB prototype board
*You will also need a TTL to USB module or an Arduino UNO board for the programming procedure.
Tools: You will need a soldering iron and hot melt glue gun and of course a 3D printer.
Step 2: The Circuit
Take your time and make your circuit as small as you can so it can fit inside the can robot.
Step 3: The Code
Connect your circuit with TTL to USB module (or Arduino uno board - note - remove ATmega328) with 5 cables to the programming header. The pins RX and TX must be cross-connected. You can change the speed of your small robot by changing the "speedS=10" variable - line 14.
Download the code from this step and open it with Arduino IDE. Inside you will also find all necessary libraries.
Step 4: 3D Printing Files
Here you will find the 3D files, download them from the official project page.
I would advice you to use support at your 3D printing procedure.
Step 5: Finally...
It's time to use your hot melt glue gun, watch the above images for reference.
I hope you liked this, let me know in the comments!
