In the set for the Perfect Course, you have 3 different type of cables. They are called Breadboard Jumper Cables. We would need to use them to extend the default cables on the car and to connect the car components to our new controller
We would start connecting a lot of things to the Raspberry Pi. It will be good if we could have some way of referring to the pins on the Raspberry Pi. For example like Pin 5 or Pin 26. Luckily there is such a way.
Every electronics tutorial, book or course about Raspberry Pi or Arduino will use a motor driver. Very few of the courses will actually explain why do you need a Motor Driver, what is it for?
The power in the car comes from the batteries. The batteries are in a batteries holder. About 5 of them. Two cables are connected to the batteries holder. It is very important to identify which of those cables is the plus and which is the minus.
The sixth level of the Robotics with LEGO curriculum for students in third or fourth grade.
For the first time two different robots are required to solve a challenge. Students learn how to cooperate and find a common approach to the challenges and how to distribute their roles. Various robots are built, even a crane that loads a truck. Students use two sensors at the same time so that they find their target and find out whether their partner-robot is ready with their part of the challenge.
This is the seventh level of the Robotics with LEGO curriculum for students in third or fourth grade.
In this level students focus on the rotational sensor that is part of every motor in the robotics set.
Robot constructions imitate animals and their behavior. Students create programs that check whether the robot's claws or pecks have successfully caught an object. That sensor in the motors allows the robots to go back in their lairs even after the use of unlimited movement.
The eighth level of the Robotics with LEGO curriculum for students in third or fourth grade.
In this level, students learn to use the fourth sensor in the robotics set - the gyro sensor. The robots are modeled after boats, yachts, and ships. With the help of the gyro sensor, students can set a course for their robots to a given angle and can detect deviations from the course. In open seas, there may be sea-monsters and the robots are being programmed to detect a sudden change in acceleration with the help of the said sensor.
This is the fifth level of the Robotics with LEGO curriculum for students in fifth to twelfth grades.
In this level students will learn how to work with data measured by the sensors. The concept of Algorithm is introduced and the programs perform calculations without knowing the values beforehand. The programming blocks transfer data between each other via data wires. The robots are designed to address the problems of security systems. Variety of alarm systems are built and the physical principles of different security methods are considered.
The sixth level of the Robotics with LEGO curriculum for students in sixth or seventh grade.
In this level, we introduce student-created myBlocks. Any functionality that is used in several places in a program is grouped into myBlock thus shortening the program's length. Students create blocks that return the result of calculations as an output parameter. Input parameters can change the calculations in the myBlocks. The robot constructions measure physical properties like linear or rotational speed, the fuel level in a tank, or length, area and volume.
The seventh level of the Robotics with LEGO curriculum for students in sixth or seventh grade.
In this level, student develop a memory training game. The player must remember series of actions like press a button, shake a pole, pull a lever, show one of many colors. In order to program the game, students use many variables and modify their states. Students create their own custom sounds and images, in order to reflect their own personality in the game. In the end of the level, the game stores top scores even after a full shut down with the help of text files.
This is the eighth level of the Robotics with LEGO curriculum for students in fifth to twelfth grades.
With the help of robots designed for games between students, they learn how to work with variables. Robots keep the score of each player and do calculations with the information in the variables.
In order to group functionality all the time, students use the well-known myBlocks. The concept of behavior is introduced and the programs are organized in many threads that exchange information between each other.
At the end of the level, the robots generate problems with numbers and the students must create equations.
Building instructions for a steering car. The front wheels steer through a Medium LEGO EV3 motor while the rear wheels are both driven by a single Large LEGO EV3 motor.
The new Spy is a robot with tank treads, which uses one medium motor to turn three things at once. That is achieved by a gear system. Simultaneously the robot turns its two hands up and down, but in opposite directions and its head - left and right.
The robot moves with the help of two tank treads, attached to two Large EV3 Motors.
Let's go fast. Large wheels on the back. A lot of torque, small wheels on the front, good aerodynamics. Here we go.
These are building instructions for a LEGO Mindstorms EV3 Drag Car.
We are about to connect the whole car with the lights and motors to the controller. Let's recap to know what is ahead of us, what would the process be and what is the end result of the next couple of sections when at the end we have a car controlled by the phone
Building instructions for a LEGO EV3 Robo-tank. The construction is incredibly simple, with an upright Brick, which makes it perfectly suitable for lessons with students.
Step by step guide on how to add the SD card to the Raspberry pi.
The Raspberry Pi must not be powered.
The is the whole step-by-step process of connecting the motors with the Raspberry PI with the driver and the batteries. No scheme needed. Everything is already here. In the course, the motors are part of the car and the batteries are in the batteries holder, but with this scheme, you could see the whole process.
A 3D scheme on how to connect the front steering motor to the Raspberry PI. This includes the Motor Driver and the batteries. The rear motor is also on this scene.
3D scheme on how to connect the L298N Motor Driver to the Batteries. Follow the step-by-step instructions. Be careful about the PCB terminal connectors.
3D scheme with instructions on how to connect the L298N driver to the batteries and to the motor. Just that. Connecting to the Raspberry Pi is at a later stage of the course.
