Lego robot program for elementary school students “Already at school, children should have the opportunity to reveal their abilities, prepare for life in a high-tech competitive world” D. A. Medvedev Speech by Head. ODOD, additional education teacher Vagenik I.Yu. GBOU lyceum 144 of the Kalininsky district, St. Petersburg, 2013

Robot design - what is it? Another fashion trend or a requirement of the times? What do schoolchildren do in Lego circles - design: play or study? To study technology and informatics To increase motivation to study these subjects, as well as mechanics, physics, mathematics, as well as the development of cognitive, research activities students.

Lego allows students to: study together within the same group; distribute responsibilities in your group; show increased attention to the culture and ethics of communication; show a creative approach to solving the problem; create models of real objects and processes; see the real results of your work.

WHAT WE DID IN THE CLASSES One lesson is two lessons of 45 minutes each. Typically, a two-person team works with one design kit and one laptop. According to the instructions, we assemble the model, draw up a program for it, and conduct tests. The models are very original, you can’t come up with these yourself! With some models, you can experiment, and with some - games. For each model, you can write several versions of programs, add sound and graphic accompaniment.

WHAT MORE? It is easy to assemble the model according to the instructions. It is important to understand what mechanisms allow it to move. We have studied the principles of operation of a motor that rotates an axle, a lever, a cam. Get acquainted with gear and belt drives. We learned what a pulley and a worm wheel are. Now in new models we will be able to use these mechanisms.

Robotics and Legoconstruction

• Robotics is quickly becoming an integral part of the educational process because it easily fits into the school curriculum in technical subjects. Key experiments in physics and mathematics can be visualized with the help of Lego robots.
• Robotics encourages children to think creatively, analyze situations, and apply critical thinking to real-world problems. Teamwork and cooperation strengthens the team, and competition in competitions provides an incentive to study. The ability to make and correct mistakes at work on their own forces students to find solutions without losing respect among their peers. The robot does not grade and does not give homework, but it makes you work mentally and constantly.

• Playing with robots can be fun and the learning process is faster. Robotics at school teaches children to look at problems more broadly and solve them in a complex. The created model always finds an analogue in the real world. The tasks that students set for the robot are extremely specific, but in the process of creating a machine, previously unpredictable properties of the device are discovered or new possibilities for its use are opened.
• Various programming languages ​​with graphic elements help schoolchildren to think logically and consider the variance of the robot's action. Processing information using sensors and configuring sensors give students an idea of various options understanding and perception of the world by living systems.

• This presentation introduces the designer Pervo Robot LEGOWeDo
• This construction set allows students to work as young researchers, engineers, mathematicians and even writers, providing them with instructions, tools and tasks for cross-curricular projects. Students assemble and program working models, and then use them to complete tasks that are essentially exercises in science, technology, math, and speech development courses.

• Robot Design - What is it?
• Another fashion trend or a requirement of the times?
• What do students do in lego construction classes: play or study?

• Developing children's interest in technical creativity and teaching their design through the creation of simple models, the management of finished models using simple computer programs.

• study together within the same group;
• distribute responsibilities in your group;
• show increased attention to the culture and ethics of communication;
• show a creative approach to solving the problem;
• create models of real objects and processes;
• see the real results of your work.

• The constructor has 158 elements, from which 12 basic models can be constructed.
• The LEGO WeDo PervoRobot constructor is designed primarily for elementary school (grades 2-4). It can also be used to work with senior classes. Working individually, in pairs, or in teams, students of all ages can learn by building and programming models, doing research, writing reports, and discussing ideas that arise while working with these models.

• One lesson is two lessons of 30 minutes each. Typically, a two-person team works with one design kit and one laptop.
• According to the instructions, we assemble the model, draw up a program for it, and conduct tests.
• The models are very original, you can’t come up with these yourself! With some models, you can experiment, and with some - games.
• For each model, you can write several versions of programs, add sound and graphic support

• extracurricular activities on the basis of 2-3 classes. There are 12 students. Of these, 8 boys and 4 girls. My main goal was to involve the activities of these guys.

• Formulation of the problem
• Ways to solve it in a logical way and determine which commands the robot should execute
• Construction of a robot with the necessary blocks, motors and sensors
• Programming
• Working off
• Reflection on what can be improved or changed in the design of the robot or program to better solve the problem.
• In preparation for exhibitions and competitions, analysis of the rules of the event and specifications required robots.

• It is easy to assemble the model according to the instructions. It is important to understand what mechanisms allow it to move. We have studied the principles of operation of a motor that rotates an axle, a lever, a cam. Get acquainted with gear and belt drives. We learned what a pulley and a worm wheel are. Now in new models we will be able to use these mechanisms.

• We study the basics of algorithmization.
• We build flowcharts, compare programming methods

• WeDo PervoBot provides teachers with the tools to achieve a range of educational goals:
• * Development vocabulary and communication skills in explaining how the model works.
• * Establish cause-and-effect relationships.
• * Analysis of results and search for new solutions.
• * Collective development of ideas, perseverance in the implementation of some of them.
• * Experimental study, assessment (measurement) of the influence of individual factors.
• * Carrying out systematic observations and measurements.
• * Use tables to display and analyze data.
• * Logical thinking and programming of the given behavior of the model.

• Summing up, we can say that the introduction of the course "Educational Robotics in primary school' has just begun. Methodological and didactic materials are to be finalized. But I understand that the direction of educational robotics has great development prospects. It can be implemented not only in extracurricular activities, but also in such academic subjects as technology, the world around in elementary school. That is, over time, you need systems approach schools to embedding robotics in the educational space of the school.

3 generations of robots: Software. Hard-coded program (cyclogram). Adaptive. The ability to automatically reprogram (adapt) depending on the situation. Initially, only the basics of the program of action are set. Intelligent. The task is entered in a general form, and the robot itself has the ability to make decisions or plan its actions in an uncertain or complex environment that it recognizes.
A robot is a machine with anthropomorphic (human-like) behavior, which partially or completely performs the functions of a person (sometimes an animal) when interacting with the outside world.
