About Robot Coder
Meet a little robot on a grid, with a star to reach and rocks in the way. Your child lines up arrow commands, presses play and watches the robot follow them step by step. If it bumps into a rock or the edge, it walks back to the start so the plan can be fixed.
How to play
- Tap the arrow buttons or swipe on the board to add steps.
- Press the green play button and watch the robot go.
- On a computer, use arrow keys or WASD, Backspace to delete and Enter to run.
What your child practices
- First coding steps
- Planning a sequence
