Best DIY Robot kit for beginners – Micro:Bit


Dear friends welcome to another robot video! In this video, we are going to build a robot
using a robot kit for the MicroBit board. This is by far the easiest and most fun robot
kit I have ever seen.Let’s get started! Hello, guys, I am Nick and welcome to educ8s.tv
a channel that is all about DIY electronics projects. In this channel, I share everything about
the projects I build to help you develop similar projects or inspire you to start making things
because it is easy, fun and creative. Subscribe to the channel now if you do not
want to miss any future video. If you follow my channel, you know that from
time to time I build some robots because they are fun and also a great way to improve our
skills. A few days ago I discovered this robot kit
for the MicroBit board on Dfrobot website. If you are not familiar with it, the micro:bit
development board is a relatively new development board which was released in 2016. It is developed with the intention to encourage
children to get involved with programming, electronics and making in general. It is very fun and easy to program since it
can be programmed using a nice visual programming environment using blocks. I have prepared a detailed review of the MicroBit
board some time ago, you can watch it by clicking here. Now let’s take a look at the robot kit and
what we can build with it. The kit is small in size and very well made. It comes with the robot chassis, a battery
holder and the wheels. The kit offers offers two motors with metal
gears which mean they are going to last for a long time, a buzzer, two red LEDs, an Infrared
receiver, 4 RGB LEDs at the bottom and two Infrared line tracking sensors. Also, at the top of the robot, we can attach
an SR04 ultrasonic distance sensor which is not included in the kit, or any I2C device. The brains of the robot is going to be the
MicroBit board which goes in this slot. In addition to the features of the robot kit,
the micro:bit board offers, Bluetooth, a temperature sensor, a compass, an accelerometer, two buttons,
and an LED matrix! Amazing stuff. We can build some amazing robot behaviors
with all the sensors that are available. The total cost of this robot is about 35$
which is very low in my opinion. The robot kit costs around 21$ and the micro:bit
board costs around 15$. You can find links to the robot kit and the
micro:bit board in the description of the video below. Now, let’s program the robot. The most fun and easy to way to program the
board is to use the Block Editor. All we have to do is to open a web browser
and visit this website: https://makecode.microbit.org/
The Block Editor loads up, and we are ready to develop our first program simply by dragging
and dropping commands! There are commands for everything the MicroBit
board offers. The commands click together like Lego bricks! In order to use the advanced features, the
robot kit offers we have to import an add-on to the software. We go to Settings ->Add Package and we enter
this URL https://github.com/jhlucky/maqueen here. We press the search icon and next, we import
the add-on. That’s it, now we have blocks available
to control the robot! We can read the distance from the distance
sensor, we can control the motors, we can receive messages from an Infrared remote control,
we can read the line following sensors, we can turn on or off the LEDs and much more. As a quick demonstration, I developed a simple
autonomous robot program. It took me less than 5 minutes. Now all I have to do is to attach the distance
sensor to the robot like this, download a small program to automatically load the program
to the Microbit board, connect the microbit board to my computer with a USB cable and
then press the “Download” button. After a few seconds, our robot is alive and
it can navigate around the house and avoid any obstacles it finds! How cool is that! We built a robot in 5 minutes! The behavior of the robot is very simple. We measure the distance that the distance
sensor reads all the time. If the distance is less than 10cms we stop
the robot, turn on the red LEDs, move backward, and then turn in a random direction and turn
off the LEDs. You can find a link to the program I developed
below. The program I wrote does not use all the features
of the robot. The developer of the robot kit offers more
examples. Let’s load a line following example! As you can see, our small robot can easily
follow a black line my little nephew drew on a piece of paper. This is a very impressive example of what
this small robot can achieve and the kids love it. There is even an example which allows us to
control the robot wirelessly using an IR remote controller. I had a remote controller lying around from
an old MP3 player and it works! I can control the robot using some of the
buttons on it. Of course, since this is an IR remote control
we have to point the controller directly at the receiver in order to work, but still this
is very impressive. We can achieve all this, using block commands
on a web interface! If you use your imagination and the sensor
and the features the MicroBit board offers, you can develop impressive robot behaviors. I would love to see what you are going to
build with it. To sum up, I think, this is the best robot
to buy if you are a beginner. It is inexpensive, and it is very easy and
fun to program. If you are a beginner in robotics, or a beginner
in programming in general, this is the best way to start your journey in programming. You are going to learn a lot of things easily
and then you can move on to Arduino or Raspberry Pi to build even better projects. I would love to know your opinion about this
robot kit. Please, post your comments in the description
below. Also, do you know any other robot kits that
are easy and fun as this one? I would love to try it. Thanks! If this is your first time here, I would love
to have you subscribed. In this channel, I post videos about DIY projects
twice a month. I love making things, and I believe that anyone
can make things, anyone can become a maker. That’s why I created this channel, to share
my knowledge with the community and learn from the community. I hope you will join us. I will see you in the next video! [ Translating these subtitles? Add your name here! ]

  1. hello Nikos, I have found your video by accident. I am very excited by the content because it is exactly what I was searching. I have a question though, how did you find the green blocks of the motor? I don't have them in the software.

  2. hi, thank you for your review and explaination of Microbit and arduino in youtube. im going to buy Arduino that comes with sensors kit, my question is that, are those sensors compatible with Micobit BBC?
