How to build a simple robot with Arduino and 3D printer

How to build  a robot in 5 simple steps : Creating a robot and make a robotic machine perform what you want is easy and fun! Most of the people want to see a robot perform the simple tasks like moving around or respond to simple commands . You can make a robot completely from simple DIY components or buy a DIY starter kit from scratch!

STEM technique

Building your own robot is a great way to teach yourself both electronics as well as computer programming and its recommended for kids to improve their problem solving techniques .  Stem Toys are Science, Technology, Engineering, and Math based toys geared towards learning, curiosity, and education.

How much DIY robot costs ?

Cost depends on the complexity of the robot, hobby robot can be expensive as 30$ to 100$.  New industrial robotics can cost from $50,000 to $80,000. Once application-specific peripherals are added, the robot system costs anywhere from $100,000 to $150,000

 

Step 1  –  Choose the task that your robot should perform:

If you robot should move around then you will need several motors and wheels, a controller for motors and a microcontroller as brain. A battery and distance sensors is the basic for this kind of robot.

Here is some examples :

The list of components for a generic robotic project includes the following:

  • Arduino Uno R3/Mega/Nano
  • Ultrasonic Range Finder Sensor – HC – SR04
  • Motor Driver IC – L293D
  • Servo Motor (Tower Pro SG90)
  • Plexiglass/ Plastic / Wood Body
  • Wheels
  • Power Supply / Battery

Step 3 – Assemble your Robot

Step 4 – Setup your computer and coding

1. Install Arduino IDE

2. Install dependance libraries

3. Plug-in Arduino in your Computer

4. Download & Install Arduino Driver ( if you using CH4030 drivers, download  from here )

5. Select Tools  > Board > Arduino

7. Select Tools > Port > and check that a new port will appear when pluggin your Arduino to your PC

6. Verify that you can upload code

 

Step 5 – Code your robot

Well done you are now able to code your robot !

Upload this code into Arduino

 

Bonus – 3D print your robot enclosure !

TinkerCAD  is like “Minecraft” for modelling :  Tinkercad is easy to use, simple and allows working with STLs directly ( for 3D printing). The software run online with your personal account in the “cloud”. We recommend this for youngers who want to build and print their creations!
