88 - Sensor Fusion

The goal of this experiment is to build a torsion pendulum and measure a phase-space-trajectory with a mobile phone. Sensor fusion is a technique that combines raw data from multiple sensors to get a more accurate estimate. We will exploit sensor fusion implemented on the mobile phone to measure device orientation.


  • Smartphone
  • Computer
  • String, Ruler
  • Cardboard box or something to put the smartphone and possibly weights in (it's the mass of the pendulum)
  • Python-skills are recommended
