Rover  Not  Moving

There are trouble-shooting lessons for each robot in their respective tutorials & lessons.  The Roli robot lessons includes a detailed procedure to help diagnose incorrect wiring connection issues and instructions for cleaning Roli's gearboxes.  If the Roli tracks are not moving, perform these diagnostic steps:

  1. Ensure that you are using the latest Roli project included in the latest ARC (formerly EZ-Builder) installation.  ARC can be downloaded here.
  2. The H-Bridge wires may not be connected correctly to the EZ-B v4.  Check the cable connections to the EZ-B v4. See this tutorial lesson for more information.
  3. The wires inside the Roli chassis may be connected incorrectly to the motor or H-Bridge Motor Driver.  There is a diagnostic procedure to verify correct wired connections by clicking here for the H-Bridge Motor Diagnostic Lesson.
  4. All EZ-Robots contain an internal fuse for electrical short protection against fire.  The fuse may have been damaged by accidental wiring mishaps. The fuse may be checked by clicking here.
  5. If the above steps appear to all be okay, it's possible that Roli's gearbox may need cleaning.  This is more likely after extended use.  Instructions for cleaning the gearbox can be found here.
