Painting & Programming: An Interview With Artist/Engineer Bob Belt

Our Artists & Engineers series replaces the actor/model with the artist/engineer,  a STEAM slash-something that is really worth looking up to. Get inspired by the individuals and collectives we interview, including Laetitia Sonami, Mitch Wenger, Arthur Ganson, and Ozobot’s own Bob Belt below, as they open up about the projects they’re excited about, where they think technology is headed, and what advice […]

How Art Conservationists Use STEAM Skills to Restore Priceless Works

One of the biggest mistakes that parents, teachers, administrators, and even kids make is separating science and technology from art. Not only is technology often used to create art, but artists use a variety of principles and elements from chemistry, biology, and physics to create their works. A watercolor painting is actually a science experiment […]

Exploring Motion In Sculpture: An Interview With Artist/Engineer Arthur Ganson

Kinetic Sculptor Arthur Ganson has been perfecting his art since 1977. His work is extremely unique and has been exhibited in numerous galleries and museums in the U.S. and Europe, including the MIT Museum and The Exploratorium in San Francisco. The New York Times and Smithsonian have covered Ganson’s inventions. These creations, rather than serving […]

Pyrotechnics & Programs: Evo Does the Fourth of July

Got Fourth of July plans? Well forget them, because we’ve got some other ideas for you…

First off, don’t miss our Fourth of July Giveaway. We’re giving away an Evo Prize Pack to two lucky Ozobot fans, and entering to win couldn’t be easier!

4th of July Giveaway

Also, Evo wants to propose a firework of a different kind this year. Fourth of July fireworks are easy on the eyes, but not so easy on our environment. According to Gary Fuller at The Guardian, the prettiest parts of pyrotechnics are also the most toxic. Those red, white, and blue hues we know and love? They’re produced by launching and burning tiny metal particles–lithium, barium, and copper to be exact.

During Wednesday’s Independence Day celebrations, particles will linger over our cities for hours. One study found that air particulate concentrations jump by up to 370% after July 4th fireworks displays. So why not forego the backyard blasters this year? Grab Evo and create a light show with {code} instead!

#BuiltWithOzoBlockly: Evo Fireworks

You’ll need:
1 Evo robot
A computer or tablet (for coding in OzoBlockly)

First, prepare your play space. Find a smooth, clean surface for Evo to perform on. This will be your “night sky.”

Next, open OzoBlockly. Before your start your program, think about what you want Evo’s show to look like. Knowing that OzoBlockly is sequential, meaning Evo will complete one command in the code before starting another one, we decided to have Evo do the following:

  1. Shoot into the sky. From the Movement Blocks, we selected Zig Zag, dragged it into our workspace, and set it to fast).
  2. Spin around. This one was easy: we went back to Movement and grabbed Spin.
  3. Light up like a firework! Turns out OzoBlockly had the perfect Light Effects Block, Firework, just waiting for this special day.

You can find all of these blocks in Beginner OzoBlockly. After loading and running our program (find tips and steps here), we decided we wanted Evo’s performance to go on and on, so we added a Loop Block and set it to repeat six times:

Can you create an Evo Light Show of your own with OzoBlockly? Be sure to connect with us @Ozobot and share your creation with #OzoSquad and #HackCreativity!

Create with Color Codes

Not ready for OzoBlockly? You can use Evo, Color Codes, and a slow shutter app to create and capture a light show. Find step-by-step instructions for Evo Light Trail Art here.
