Rev Up

Difficulty: level 4

Blocks used:
Movement, Light Effects, Sounds, Loops, Logic, Sensors, Functions, Math, Variables

Connect your thumbs and index fingers in a diamond shape around Evo to “rev up”. Pull your hands away when Evo’s facing the direction you want it to launch. The more you let Evo rev up, the faster and farther it will go. But be careful! If you don’t release in time, Evo will redline. OzoBlockly Hack: Use Rev Up for games by modifying the code and using color targets drawn on paper.

Color Match

Difficulty: level 4

Blocks used:
Movement, Light Effects, Sounds, Loops, Logic, Sensors, Functions, Math, Variables

Challenge: Try to match the color Evo shows you with its top light. Using your fingers, experiment with the front sensors and rear right sensor. Evo’s front lights will change color in response. Evo lets you know when you’ve got it right, then randomly picks a new color.

Loading Animation

Difficulty: level 4

Blocks used:
Light Effects, Timing, Loops, Variables, Functions

Use the Light Effects blocks to create a 'loading' animation on the Evo (in any color), which repeats forever. Turn on each light (left to right) until each light has been lit. Then, shut them all off, and the animation should begin again.

Tree Traversal Algorithm (DFS)

Difficulty: level 4

Blocks used:
Line Navigation, Light Effects, Loops, Logic, Math, Variables, Functions

Ozobot demonstrates a Depth First traversal while navigating a binary tree maze. Start Ozobot at the root of the tree and it will methodically explore all of the tree branches and return to the starting point. Then Ozobot will blink the count of the number of leaves it visited while traversing the maze.

Get Set with Fibonacci

Difficulty: level 3

Blocks used:
Movement, Loops, Math, Arrays

Learn how to set up an array, which is a table of set length that holds similar data, called elements, and reset the values. In this case, watch your bot act out the Fibonacci Sequence, a fun pattern in numbers.

List, Served

Difficulty: level 3

Blocks used:
Movement, Loops, Logic, List, Variables, Timing, Sensors

Move Evo by placing your hand or an object near its rear proximity sensors. After Evo sees something in front (like your hand), it will retrace its movements backwards. This program uses a List, which is a way to store data like a memory bank. You can access any 'element' in the list after it's been created.

Press for Adventure

Difficulty: level 2

Blocks used:
Movement, Loops, Logic, Timing, Math, Functions, Button

Press the button to have Evo play different animations. Try 1 press, two, or three. You have 2 seconds to input your choice! Play any animation at any time.

Not-So-Random Walk

Difficulty: level 3

Blocks used:
Movement, Light Effects, Loops, Math

This example is like the 'Random Walk' example in Mode 4, but this time the movements aren't so random! That's because the 'random number generator seed' causes the same sequence of random numbers to appear, depending on the range of integers given. Run this program multiple times to see that you will get the same sequence of actions every time. Change the seed number to get a new sequence of actions.

Always Even

Difficulty: level 3

Blocks used:
Loops, Math, Sounds

Change numbers to a nearby even number, or stay the same if already even.

Remix to Disco

Difficulty: level 3

Blocks used:
Light Effects, Loops, Math, Timing, Variables

Learn how the LEDs and colors correspond to specific integers by seeing how the 'disco' light animation is remixed to remove the top light (which is represented by the number 1, or any odd numbers in the 'mask').

IR Communication Beacon

Difficulty: level 1

Blocks used:

IR Communication Dialogue

Difficulty: level 5

Blocks used:
Movement, Light Effects, Sounds, Loops, Logic, Math, Variables, Functions, Terminate, Communication

This is a functional demo of a dialogue between two robots. The program is to be loaded to two robots. The robots are standing still until they are placed in close proximity. When they detect each other, they turn to each other and start a trivial small talk. After there is nothing more to say, each robot moves away and then turns itself off.

Gatekeeper

Difficulty: level 3

Blocks used:
Movement, Light Effects, Loops, Logic, Functions, Communication

Transform one from your Evos into a mean gatekeeper who stops anyone who wants to get past him. The other Evo (hero) has to search a maze to find the secret formula to conquer the gatekeeper. The gatekeeper waits for a specific IR message on its front sensors. The hero starts sending it when it sees green line. (You need two Evos for this example. Load the Hero program to one of them, and the Gatekeeper program to the other.)
