Lego Boost Vernie Junior
If you have Lego Boost, you must have built a Vernie robot. It's great but it's very big and takes a long time to build it.
This is Vernie Juior. It can move, shoot and it's much smaller so you can build it very quickly.

I’m a little obsessed with Pinball. I've already built some versions of them, but this one is very special because it is built of the pieces of one set.
If you have Lego Boost 17101 set and Road Base Plate you can make it. To download the building instructions and the Scratch program click links below.
Good luck!
Can we use two Lego Boosts on two computers in Scratch at the same time?
This is possible, but you must keep the order to have control which BOOST is connected in which computer.
For details, see the video.
Lego Boost sensor can measure Color and Distance, but in Scratch distance measuring is not supported.
Below there are two examples of using the color sensor:
- vehicle that move on the white
- line follower
The Lego Boost hub has two tilt angle sensors inside. First sensor measures tilt angle up and down, second one measures right and left. The video shows how to use sensors to move the sprite in a simple game.
Lego Boost Egg Decorating Machine built using 17101 set, programmed in Scratch.
The patterns may be different, depending on the size of the eggs. After building, raise the marker by pressing the up arrow.
To see how to use Legoo Boost with Scratch, watch this video: Lego Boost with Scratch
To steering the Boost vehicle like in PC games you need to program driving forwards, backwards, right and left. For each direction you must turn on the motors and wait until arrow key is not pressed.
In order to use Lego Boost with Scratch you must install and run Scratch Link, turn on bluetooth in your computer and load Boost extension in Scrach.
We can use motors, tilt angle sensors and color sensor. Distance sensor is not supported in Scratch.
In this video I've tried to show how to install the required stuff and how to use to motor and sensors.
This video shows very simple Scratch code to EV3 sumo fights. After starting the robot goes straight. When it leaves the white circle, it turns left. When something gets in its way, it speeds up.
We can change the robot's operation by changing turning left time and changing of the detection distance from the other robot.
I used the set Lego® Friends Olivia's Hamster Playground 41383 to show you how to control the EV3 motor speed in Scratch.
The motor speed can be set in Scratch by the "Motor A set power block". In this block we can enter the power in percent or substitude a variable.
In the first examle I'm setting the power with the arrow keys.
In the second example I'm controling it by another motor.
