Test Activity Board Arlo's Motor Connections

Test Activity Board Arlo's Motor Connections

This next program sets the Arlo’s motors to 20/127 of full power in the forward direction.  If your Arlo goes forward while running this program, it indicates that your motors are connected correctly.

Check the picture at the start of this document and make sure you know the Arlo’s forward, backward, left and right.

IMPORTANT: Your Arlo will not be ready for the next step until it goes forward for this test.

  • Turn off the Arlo’s Motors rocker switch.
  • Run Arlo - Test Motor Connections.bs2.
  • The SimpleIDE Terminal will display a communication failure because your DHB-10 isn’t responding.  Don’t worry about it, the DHB-10 didn’t reply because Motors power is off.
  • Turn all power switches off.
  • Take your Arlo to an open space with at least 2 m of open space for forward travel.
  • Turn all powers on: Arlo MAIN & MOTORS and Activity Board power to 2.
  • Verify that the Arlo goes slowly forward for 3 s, then stops.
    • If it does not go forward, check the Arlo Fails Motor Connections Test section in the Troubleshooting Guide at the end of this document.
    • If it does go forward, your Arlo is ready for the next step (Test Encoder Connections).
