Ozobot Evo: screen-free color codes plus Blockly for early coding
Ozobot's Evo App (iOS/Android) is the companion to the Evo robot, spanning PreK–2, 3–5, and 6–8: students start with screen-free color codes the robot reads off paper, progress to on-screen Blockly programming, and can use MetaBot — an augmented-reality robot — plus virtual Color Code Magnet Kits. The experience won an ISTE award.
Low infrastructure demands and visible, movement-based learning make this a practical station activity for early grades — a marker and paper start coding class. The page omits pricing and technical requirements rather than stating them; get the full quote picture before budgeting.
What the source says
We read the original and outlined it point by point — in the source’s own order.
- The Evo App is a STEAM companion app for the Evo robot, on iOS and Android, for classroom and personal use.
- Students build tracks by selecting tiles and watch Evo drive the programmed path.
- Learning progresses from color coding (screen-free) to visual block-based programming via an “Edit Blockly” mode.
- MetaBot adds an augmented-reality experience the page bills as the first AR experience designed for education.
- Grade bands referenced: PreK–2, Grades 3–5, Grades 6–8; the experience won an ISTE award.
Notes from our read
- Color coding needs no screen at all: markers, paper, and the robot.
- The page states no pricing, no subscription terms, and no minimum OS versions — those omissions are due-diligence items, not reassurances.
- One tiny robot per station works for rotations — a low-robot-count model that fits small budgets.
- AR (MetaBot) requires a device with a camera; the screen-free mode is Evo's distinctive strength.
In plain words
Evo is a robot the size of a golf ball, and its best trick needs no screen at all: a child draws lines and colored patterns on paper with ordinary markers, and the robot drives the lines, reading the color patterns as commands — red-black-red might mean “turn left,” a certain sequence means “speed up.” The child is programming, genuinely, with a marker.
That's real computer science in disguise: symbols in a sequence telling a machine what to do. When students outgrow the markers, the app's Blockly mode moves them to snapping code blocks on a tablet — the same style of coding used in most elementary programs — and an augmented-reality mode (MetaBot) puts a virtual robot on screen when the physical one is charging or shared.
For a PreK–2 classroom or a low-budget one, the screen-free start is the selling point: no laptop cart, no login, no Wi-Fi — one robot and a box of markers makes a coding station. The honest gap in the product page is money: it lists no prices, subscription terms, or device requirements. That's not disqualifying, but it means a school's first email to the vendor should ask for the complete cost picture in writing.
