Classes with students, Construction

Body

After you finish constructing the robot, take two touch sensors. Attach them to each other with beams. These sensors would be your remote control. Place them in a comfortable distance from each other.

When you finish constructing the remote control, attach the robot and the remote control with cables.

Courses and lessons with this Tutorial

This Tutorial is used in the following courses and lessons

Robotics with LEGO - Level 1.5 - Spy games

The second level of the Robotics with LEGO curriculum for students from fifth to twelfth grades.

Students build multiple robots with thread chains and become familiar with the physical concepts of momentum and center of gravity. The concept of gears, their use and basic constructions involving gears are studied.
The new concept of "condition" is introduced in programming. Robots are becoming smarter as they can make complex decisions on their own. "Spy robots" follow their targets and avoid being noticed. This level introduces the light sensor which the robots use to recognize the colors of the objects they are looking for. Robots can stop on a black line and follow a route marked with a colored line on the floor.
The spy's most complex mission in the end of the level is to turn into a sumo wrestler and defeat any other robot in the ring.

Lesson 1 - Defusing bombs

Introduction

Level B1. "Spy gadgets". Robotics with LEGO

The third level of the Robotics with LEGO curriculum for students in second, third or fourth grades.

In these lessons, we stress on more complex and challenging robots. The concept of Condition is introduced. Students learn about physics concepts of inertia and center of mass. Robots with two sensors are built and students program both of them. Programming becomes more complex as robots now can make complex decisions. "Spy"-robots sneakily follow their targets, trying to be undetected.

Lesson 3 - Remote Control

Intro

In today's lesson we would play the role of the spy. Your goal is to slow down the villains that are loading dangerous weapons on a ship. You need to slow them down until the police arrives. The villains are planning to hide the weapons into boxes for cakes and to transport them with ordinary ships. This gives you the idea to steal some of the boxes with weapons and to let the villains search for them. This will surely slow them down. But these are heavy boxes and there are a lot of villains. To achieve your goal you must use a robot.

You still can not program one robot to do everything, but for every task there is a different robot that could help. In every days tasks, spies have to deal with a lot of different situations and adapt to them. In the same way the robots they use must be smart enough and adapt to different situations. You must program the robots to allow you to remotely control them and decide how to accomplish the next task.

Robotics with LEGO - Level 2.0 - Robots in Factories

The third level of the Robotics with LEGO curriculum for students from fifth to twelfth grades.

Robots in this level use two or three sensors at a time and students create more complex programs for them. The work of the differential and its usage in vehicles with one drive motor is explored. Robots interact with each other and transfer information or material between themselves. Students learn in depth how to create smoother line-following programs. In the end of the workday, robots leave the conveyor belt and relax with a recreational game of volleyball.

Lesson 1 - Crane

LEGO Mindstorms EV3 Crane robot is used to lift, move and load cargo on a cargo truck. There is a mechanism for grabbing a cargo load (eg a blue ball). Crone is also a tower crane and there are balancing wheels on the opposite site of the grabbing mechanism. It was an ultrasonic sensor.
