About Robot Coding Lab
Robot Coding Lab teaches the ideas behind programming without any typing. Beep the robot needs to reach a battery on the lab floor, and children build a program from arrow blocks to get it there. Press Run and Beep follows the program one square at a time, with the current block highlighted, so children can see exactly what their instructions do. When a run goes wrong the game gives a precise clue — “Bump! Beep hit a crate on move 4” or “Beep stopped 2 squares away” — and highlights the block responsible. Later levels add gems to collect, then a block limit that can only be met with repeat loops, and finally Bug Hunt, where Beep's program has a mistake for children to find and fix. The Lab Designer lets children build their own puzzles with crates, gems and a battery, then program Beep to solve them.
What children learn
- Put instructions in the right order to reach a goal (sequencing)
- Plan a route around obstacles before acting
- Spot repeating patterns and write them as loops
- Find and fix mistakes in a program (debugging)
- Break a bigger journey into smaller steps (decomposition)
Tips for parents
- Play “robot” at home: your child gives you arrow instructions to walk to the sofa, and you follow them exactly — mistakes included.
- Before pressing Run, ask your child to trace the route with a finger.
- Celebrate the bug clues: finding out what went wrong is what programmers do all day.
- Use Step mode to slow things down for younger children.
- Challenge older children in the Lab Designer to make a level a parent can't solve first time.
Tips for teachers
- Matches the CSTA K–2 standards 1A-AP-10 (programs with sequences and simple loops) and 1A-AP-14 (debug errors in sequences and simple loops).
- Works well in pairs: one pupil plans aloud, the other places blocks, then swap.
- Bug Hunt levels make good starters for a discussion about debugging strategies.
- Absolute arrows (up, down, left, right) avoid left/right turning confusion for younger pupils; follow up with an unplugged turning activity for older ones.
Robot Coding Lab FAQ
Does my child need to read or type to play?
No typing at all. Programs are made from arrow and repeat blocks, and every level's instructions are read aloud. Some reading helps with the clues, which are also spoken.
What age is Robot Coding Lab for?
Ages 5 to 10. First Steps suits kindergarten; loops and Bug Hunt suit children aged about 7 and up.
What does a loop do in the game?
A repeat block runs the arrows inside it several times. Loop Lab levels allow only a few blocks, so a long trip like “right seven times” has to be written as one repeat block instead of seven arrows.
Can children make their own levels?
Yes. The Lab Designer lets them place crates, gems, the battery and Beep on a 6 × 6 floor and program a solution. Designs aren't saved or shared anywhere.
Is it free and safe?
Yes. It's free with no sign-up, no chat and no personal information. Stars are saved only in your browser.
