Installation

OmniMount

To configure OmniMount, follow these simple steps:

Install VMX-pi onto your robot. ENSURE that one of the VMX-pi axes (as shown on the

VMX-pi circuit board) is perpendicular to the earth's surface. This axis will become the

yaw (Z) axis. Note that this axis can either be pointing away from the earth's surface, or

towards the earth's surface.

Press the 'CAL' button on the VMX-pi Circuit board AND HOLD THE BUTTON DOWN

FOR AT LEAST 5 SECONDS.

Release the 'CAL' button, and verify that the orange 'CAL' light flashes for 1 second

and then turns off.

Press the 'RESET' button on the VMX-pi circuit board, causing it to restart.

The VMX-pi circuit board will now begin OmniMount auto-calibration. During this auto-

calibration period, the orange 'CAL' LED will flash repeatedly. This process takes

approximately 15 seconds, and requires two things:

1. During auto-calibration, one of the VMX-pi axes MUST be perpendicular to

the earth's surface.

2. During auto-calibration, the VMX-pi must be held still.

If either of the above conditions is not true, the 'CAL' LED will be flashing

quickly, indicating an error. To resolve this error, you must ensure that conditions

1 and 2 are met, at which point the 'CAL' LED will begin flashing slowly,

indicating calibration is underway.

Once the VMX-pi auto-calibration is complete, the Board Frame to Body

Frame Transform will be stored persistently into VMX-pi flash memory and used until

auto-calibration is run once again.

The VMX-pi circuit board contains sensitive circuitry, and should be handled carefully.

An enclosure is recommended to protect the VMX-pi circuit board from excessive handling,

"swarf", electro-static discharge (ESD) and other elements that could potentially damage the

VMX-pi circuitry.

An enclosure for the VMX-pi is available.

Build vs. Buy

Those who prefer to print the enclosure using their personal 3D printer, enclosure design files is

available in the "enclosure" directory of the .

Those who prefer to purchase the enclosure can order it from . The price will be approximately

$65 plus shipping, depending upon the type of material used.
