Components of a Machine Control System
Drag your cursor over the image below to view detailed pictures and descriptions
Computer
This particular computer was produced by KEE Technologies, which recently acquired by Topcon Positioning Systems, Inc. The software running on this unit is Carlson Grade from Carlson Software.
GPS Receiver
This is a Sokkia 2600 GPS unit with a Satel Radio Modem. While this mounting method is not preferred, it does allow the unit to be quickly removed and replaced in this open cab environment.
GPS Antenna
Atop this mast resides a Novatel ANT-532-C which is an active L1/L2 GPS Antenna that is also aircraft rated.
Hydraulic Controls
This is the user interface for the MOBA hydraulic controls. Not pictured is an electro-hydraulic valve plumbed parallel with the OEM manual hydraulic valve.
Slope Sensors
These are MOBA slope sensors. The one on blade is a single axis while the one on the mast mounting plate is a dual-axis.
Junction Plate
This particular junction box, while a common point for connection problems, provides a quick means of detaching the expensive hardware out front, in case the dozer needs to be used for harsher tasks like clearing brush.
Under the Hood MOBA Interface
This particular box is a junction point for all the MOBA hydraulic controls and sensor signals. Note the CAN-RS-232 control hanging in the picture.
