This is a program that sets the VEX IQ Controller to control The Roberto Bot chassis with Modkit for VEX. This program can be used and for other robots/chassis.
The robots are available at:
This is a program that sets the VEX IQ Controller to control the Roberto Bot With Four Bars Lifting Mechanism, and also Sports Chassis With Eight Bar Lifting Mechanism - VEX IQ Robot.
This is a program for communicating with LEGO Mindstorms Bluetooth between two bricks. The goal of the program is to control one of the bricks with another brick. The controller has two touch sensors that control the direction and two buttons on the brick itself that control the power.
The control brick has two motors attached that are controlled.
The goal of this program is to be used as an example of how to use the EV3-G Bluetooth. Yes, it requires two bricks, but most of the schools have two bricks and could test the program.
This is a program that sets the VEX IQ Controller to control the Pesho Bot With Two Bars Lifting Mechanism Controls.
The block has one parameter for the port where the medium motor is connected.
This is a simple program that shows how does the "subscriber" in MQTT server model works. It's a little bit more complicated than the "publisher" but it is still the basic things you need to know. As in the publisher we have an IP address which you have to edit to your case, for more explanation you can see this program. It also have a Client instance, but this time we have to "subscribe", not to "publish". The more complicated thing here is that we have one function called "on_message". It prints the topic and the message, which is posted. Our client is subscribed to topic "Air Conditioner" respectivly the printed topic always will be "Air Conditioner". The function is called every time when somebody post a message on this topic. For this purpouse we have the "on_message", which actually catches the messages. For now we'll not discuss what magic stands behind the "on_message". The last thing you need to know is the infinite loop which we start, because our "subscriber" have to check non-stop for messages.
This is a simple program that shows how does the "publisher" in MQTT server model works. It publish "On" as a message on a server with IP address 192.168.1.105. Be carefull, we have already installed an instance of MQTT server on your Raspberry. And it lives on your Raspberry so the server has the same IP addres as the Raspberry. This means that you have to replace the IP addres in the program, with the addres of your Raspberry. If you forget it you can type "ifconfig" in the command promt and search for the "inet" line.
wlan0: flags=4163 mtu 1500 inet 192.168.1.105 netmask 255.255.255.0 broadcast 192.168.1.255
The name of the client in this case is "Publisher 1" and the message is posted under the topic "Air Conditioner".

Playing Football with robots is extremely fun. It could be part of the classes, it could be part of demonstration days. This is a EV3 LEGO Mindstorms Project including the programs for controlling the WRO Football Striker and the WRO Football Goalkeeper, as well as all of the necessary My blocks.
These are the programs for our boxing robots and their Joysticks. They are made for a game of two fighters with their respective joysticks, fighting until one is knocked out or its "heart" touch sensor is punched by the other robot. The fighters require the two "leg" motors to be connected on ports B and C and the hand medium motors on port D. The touch sensors should be connected on port 1, however keep in mind that the game may be better without them. The distance sensor has no purpose in the program as it is used only for aesthetics. The joysticks require the motor for forward and backward to be connected on port B and the motor for left and right to be connected on port A. The touch sensor operates the hands and must be connected on port 4.
Part of the Perfect STEM course, you should have a Raspberry Pi and a HC-SR04 distance sensor connected to 5V, GPIO 5, GPIO 6 and GND.
Part of the Perfect STEM course, you should have a Raspberry Pi, a button connected on GPIO 26 and 3.3V, and two motors connected to GPIO 27, GPIO 22, GPIO 23 and GPIO 24.
Part of the Perfect STEM course, you should have a Raspberry Pi and an LED connected on GPIO 18 for this example to work.
Part of the perfect STEM course, this program needs a Raspberry Pi, a button connected on GPIO 26 and 3.3V, and an LED connected to GPIO 18.
The block has the following parameters from left to right:
EV3 PLF-block for LEGO front-wheel steered robots. The block has two relaxation coefficients – one for steering to the left and one for steering to the right. The aim is to make the robot follow a line smoothly when the color sensor is positioned closer to one of the wheels.
The block has the following parameters from left to right:
