For The Purpose of This Presentation…
A Machine Guidance
system will be
considered to be one that uses automation
to provide the equipment operator a visual
indicator
of the position of the cutting edge

indicator
of the position of the cutting edge
(blade, bucket, screed, etc) relative to the
design surface being constructed.
For The Purpose Of This Presentation…
A Machine Control
system will be one
where the cutting edge of the equipment is
fully controlled by automation
.
The system is connected to and controls the

The system is connected to and controls the
hydraulics while the operator simply drives
the equipment and manages the

Advantages
Construction Automation – Ron Singh
22

High enough accuracy for most
applications (except where elevation is
critical)
One base - many rovers
Works in all weather conditions (and at
night)
Guidance/Control by GPS
Height accuracy is not as good as total

Total Station Grading
+/- 5mm or 0.02’
Control by Total Station
 Started in the early
1990’s with robotic
motorized total
stations that could

track a prism
mounted on a
machine
 Could position the prism to high accuracy -
equivalent to string lines and lasers
Control by Total Station
 Information from the prism position could be
sent to the machine, which would adjust the
hydraulics accordingly.

Control by Total Station
 No longer needs string
lines. Same accuracy
