Self-driving vehicles have a number of features designed to keep occupants safe. In this activity, students program some of these features into mBot.

NOTE In this activity, students are presented with a set of scenarios to engage their creativity and challenge their coding skills; step-by-step directions are not included as the activity is intended for students who are familiar with programming mBot using the mBlock Blockly app.


  • Practice writing code for mBot to complete a task (forward collision warning, automatic emergency braking).
  • Apply an understanding of the mBot Ultrasonic Sensor to mimic the safety features of realworld autonomous vehicles.
  • Learn how to use the mBot Light Sensor to detect low light conditions and trigger a change in mBot’s speed.
  • Troubleshoot coding issues when problems arise.
