Build instructions

Anglerfish

Do you like fishing? If so, you must have heard about anglerfishes. This Anglerfish behaves the same way. Just move the robot as if it was swimming. If this movement detected by the Gyro sensor, open its mounth. Then you need to take an item in front of the Color sensor as if it was the fish. After that, put it into the mounth of the Anglerfish. Be careful! It bites.

Build instructions

Ball Conveyor

It is one example of many possible solutions for making system to move balls. It waits until the Color sensor sees a change in reflected light intensity mode then the conveyor lifts the ball up onto the ramp. The system waits until the Touch sensor is pressed by the ball. Finally, your program should generate a number between -1 and 1 and based on this value, it should throw the ball to the right or left.

Build instructions

Bevel Bot

If you build the Bevel Bot, you will show how to build a gearbox using 12-tooth bevel gear along with the 16-tooth straight gear with double bevels. These gears actually rotate at right angles to each other. Since the medium motor drives the smaller gear, the output of your gearbox is actually slower than the motor. However the robot will be slower, you will gain torque in this system.

Build instructions

Color Sorter

This Color Sorter is used for sorting colored items. It uses two motors. The large motor moves the head of the sorter on conveyor belt according to the color of the item and the medium motor pushes out it. You need to detect the color of the item using the Color sensor next to the Brick before putting it into the sorter.

Build instructions

Elephant

What do you think about which parts you could control this Elephant? You can move it forward or backward, and pick up an object or lift the trunk. Implement these movements using the EV3 buttons and see how it works! For a better feeling, write a core to play an elephant sound when the middle button is pressed!

Build instructions

Flower

How beautiful when the sun shines and the flowers are opening, is not it? You can perfectly simulate this wonderful activity using the Flower robot. It should open when the light intensity is high and close when it is low. You just need to write a simple code that does this. Use the Touch sensor to instantly close it.

Build instructions

Gear Bot

Do you notice the two gears on the robot's wheels? This is why it is called Gear Bot. Due to these gears, the robot can only go slowly, but it is much stronger. You can test its power by building a rising track. See how it goes!

Build instructions

Gyro Boy

Try to keep the robot in balance by changing his speed depending on the information coming from Gyro sensor. If the robot has fallen, put it back on the stand and use the Touch sensor to start it again. The Ultrasonic sensor is responsible for checking if an obstacle is in front of the robot. If there is, the robot should stop then turn away by moving slightly back and waving its arms. There is also a Color sensor, use it for changing the behavior of the robot.

Build instructions

Gorilla

Shake your hand with the Gorilla to make him happy! This robot is ideal for creating a robotics system that interprets different signals and responds to them with different behavior. Your task is to write a program that controls the Gorilla. It should raise his arm if it detects that you are close to it and wait until the Touch sensor is bumped. After that, it should rise his both arms then move them in opposite directions for a while. But if the Ultrasonic sensor detects someone close and it is dark, then it should not do anything.

Build instructions

Insect

Whould you like to program a robotic creature that can sense its environment and respond by moving? If so, you need to build the Insect and write a program for controlling it. The program should start when you press the black wings of the Insect. If they are pressed, you should start its motors forward for some seconds then backward for some seconds. If the Ultrasonic sensor sees something, the program should turn both motors forward at 100% until the Touch sensor on the front of the Insect is pressed.

Build instructions

Plot bot

What do you think I would say you can drawing by controlling a robot? You will be able to do it if you build this Plot Bot! You just need to insert a pen or pencil to the pencil case of the robot and drive it! It will draw a line as you drive your robot.

Build instructions

Pen arm

This is a smart way to draw circles or semi-circles on a paper like a compass. On the top of the arm, you can find a Gyro sensor. Using this sensor, you can determine in degrees how long the arc length is of the circular sector you want to draw. The Touch sensor is responsible for starting the drawing. Use the Color sensor to draw preset circles.

Build instructions

Pick and Place

This solution is one example of many possible solutions for making systems that pick and place objects. Robots with such construction are often used in the automotive industry. Bump the Touch sensor to start the program and reset the Gyro sensor. Pick up an object then place it to other direction using only the Gyro sensor. Then put it down and turn back to the previous state and grab another one, and so on. Repeat these steps until the Color sensor sees dark.

Build instructions

Puppy

The goal of this puppy robot to make him happy. Write a program that simulates 7 possible behaviors: sleeping, payful, angry, hungry, bathroom, happy and waking up. You can use the Touch sensor on his back and the Color sensor near his month to pet and feed him. There are also 2 motors for standing up and sitting down the puppy and 1 for shaking his head. Use randomly generated numbers of pets and feeds as target. If you reach those targets, he will become happy.

Build instructions

Remote Control

Would you like to remotely control another robot? Then you should build this Remote Controller! You can move a robot forward and backward by rotating this Controller forward and backward. You can use the wheen on the Controller for turning a robot for example right and left. There is also a Touch sensor for signaling to the robot to do some action.

Build instructions

Robot Arm

You can use this robot to move an item from one place to another. You can define movement patterns for the robot exactly where to pick up the items and where to place them. Identify the patterns with the colors and use the Color sensor to set the required pattern. Finally, press the Touch sensor to start the operation.

Build instructions

Sorter Bot

This robot rolls on wheels and puts items in a different position according to their colors. There are two large motors to drive the sorter. The medium motor is responsible for pushing the item out. Use the Ultrasonic sensor to avoid wall hitting.

Build instructions

Spinner Factory

It is an example of automation on a small scale. You can build a working model of a production line and program the steps need to construct and launch a spinning top. Use the color sensor to specify the items to be spin. Then the robot looks at all the items and collects the required ones by pressing the Touch sensor. Finally, spin them out using the medium motor.

Build instructions

Stair Climber

Use this robot for climbing stairs! In order to move the rear section of the robot, the entire robot must have in sync, so the rear wheels are moved at the same time as the rear stucture. Once the structure hits its limit by hitting the Touch sensor, it is moved slowsly to its start position. The Gyro sensor helps you to keep the robot in balance while climbing. Use the middle button of the Brick to increase the number of stairs to be climbed.

Build instructions

Tank Bot

Drive the Tank Bot in a shapes based on button presses. Create a program to control the reactions when the buttons on the Brick are pressed. The Brick has 5 buttons, so you can drive the robot along 5 different shapes: triangle, rectangle, pentagon, etc. Do not forget to draw the current shape on the display!

Build instructions

Toddle Bot

This Toddle Bot acts just like the real toddlers: crawl on all fours. If you would like to see something cute, you have to build it! It is really simple to build it and you just need to drive 2 motors.

Build instructions

Turtle

The turtles often retract their neck when you touch them. You should write a program that draws two eyes on the EV3 display. If the Turtle was rotated many times, you should animate its eyes as if the Turtle was dizzy.

Build instructions

Znap

Bite if someone is too close! Znap is a reactive robot who want to drive around in small pattern and react to an object in front of him. Write a program to check if someone is too close. If yes, warn him with a hiss. If he come closer, do a full bite!
