Simulate and test robot behaviour
Use a simulation to test behaviour before considering hardware.
Original Kidemy beginner self-study unit · Learn the idea, try the practical activity and review your written answers. Review your project with a guardian or teacher using the criteria below. Teacher-led course approval and booking are separate.
Learn the idea
A simulation models selected features of a real system. Our grid models position, direction, blocked squares and a target. It does not model wheel grip, battery level or every real obstacle. A successful simulated route is useful evidence about the instructions, not proof that a physical robot will behave identically.
Worked example
If the grid blocks a square, a forward command leaves the robot in its current square and explains why. Revise the route around the obstacle, then reset and test again.
- Read what the model includes and leaves out.
- Predict the next state before pressing a command.
- Compare the observed state with your prediction.
Try it step by step
This is a practice model. It does not change your Kidemy coins or school grades. Use the buttons to test one instruction at a time.

Accept a real-world feature that this grid does not model.
Prediction log
Record a prediction and result for three different grid commands, including one blocked move.
Review with a guardian or teacher
- Predict before testing.
- Record what actually happened.
- State one limitation of the grid.
