LEGO SPIKE Prime Robot Turning Simulator
An interactive educational tool designed to help students understand the mathematics behind robot movements. Calculate precise wheel rotations needed for turns at different angles and steering values. Visualize the robot's path around obstacles with real-time feedback. The tool generates ready-to-use Python code for SPIKE Prime, making it easy to implement calculated movements in actual robots. Perfect for STEM education and robotics competitions.
Robot Turning Simulator
Calculate wheel rotations and visualize the robot's turning path
Robot Parameters
This is the angle you want the robot to turn
Higher values create tighter turns
Circumference: 17.6 cm per rotation
Diameter
5.6 cm
Distance per rotation
17.6 cm
Adjust if your robot over or under turns
Calibration Tips
- Set the turn angle to 90° and run the generated code.
- Measure the actual angle your robot achieved.
- Divide desired angle by actual angle to get the correction factor.
- Update the calibration factor input and recalculate.

Formulas Used
1. Turn Diameter:
88 × 1.6(-steering/10)2. Arc Length:
(angle / 360) × π × diameter × calibration3. Wheel Rotations:
arc length / wheel circumference4. Motor Degrees:
wheel rotations × 360Step-by-Step Explanation
1. Choose wheel, steering value, and direction.
2. Estimate the turn diameter using the exponential fit.
3. Compute arc length and wheel rotations with calibration.
4. Convert rotations to motor degrees and generate Python code.

Tips for Accurate Turns
- Test on the same surface you'll use in competition or class.
- Fully charge batteries for consistent motor performance.
- Re-run calibration when you change the wheel type or robot weight.
- Clean wheels to reduce slippage and drift.
- Record your best calibration factor for future runs.
