Do not enter lanes where an autonomous truck is traveling |
Illustration 1 shows AMT "A" traveling forward in a lane for which the truck has permissions. Light vehicle (LV) "B" is shown traveling perpendicular to AMT "A". Although LV "B" is within the perception systems field of view, illustrated by the dashed line, the LV will not trigger the AMT to stop until the LV enters the lane.
Illustration 2 | g03320186 |
(A) Obstacle detected
(B) Obstacle cleared within allowed time |
In Illustration 2, the AMT has detected the LV but the LV clears within the allotted time so the LV does not trigger the AMT to stop.
Illustration 3 | g03320189 |
(C) Obstacle detected
(D) Stopped truck no longer sees the obstacle |
In Illustration 3, the AMT has detected an obstacle (1) that is shorter than 1 m and stops, but after stopping the perception system no longer sees the obstacle.
When operating a machine utilizing Terrain for grading and loading or using Detect, allow for proper start-up time. Before moving the machine within the area of autonomous operation, review the status bar and ensure that the on-board radio module and the satellite receiver are functioning and reliable. Moving the machine before the machine has established good radio communications, established an accurate position, and updated the mine model can cause the machine to not be seen by the autonomous mining truck and other equipment operating in the autonomous area which may result in serious injury or death. |
When first starting up a machine utilizing Terrain for grading and loading or using Detect, allow for proper startup time. Review the Status bar to ensure that the onboard radio module and the satellite receiver are functioning and reliable before moving the machine within the area of autonomous operation.
Reference: Refer to Operation and Maintenance Manual, M0102733, "System Startup and Shutdown" for detailed information regarding the buttons and icons on the Status bar.

Configuring the Reference Point of the Machine for Load and Dump Operations
To fix and track spotting operations correctly for loading and dumping, Terrain assumes a reference point on the machine. The reference point is the location at which the load or dump operation is to be performed. The dipper tooth or blade tip is the default reference point. To change the default reference point, configure an offset using the following MCU path:
- Ore Control Configuration > Spot Offset > <machine type> Set Spot Offset
Note: The offset is always along the machine axis (Y axis) and relative to the reference point. The X and Z axes have no offset component. All spot point Z values are projected to ground.
Reference: For detailed information, refer to MCU Help, "Set Spot Offset".
NOTICE |
---|
The operator must use critical judgment when setting the spot location for an autonomous mining truck (AMT). When setting a spot location for loading, an AMT will attempt to achieve the position set by the operator. Do not set a spot location that causes an AMT to move to a hazardous location. Do not set a spot location so that an AMT will contact any part of the loader. Do not set a spot location over a hole or lowered area of any kind. The AMT perception system cannot identify a hole as an obstacle. Ensure that when excavating inside the load area boundary the dynamic truck lanes are not routed through the excavated areas. An AMT attempting to move to a hazardous location, or falling into a hole because the operator did not use critical judgment when setting the spot location, may result in damage to the machine or nearby equipment. |
Dump Spotting is a feature that is available to machines on sites with a GIS database. The feature is available on all machines that have an active Command for hauling security key. As of Terrain v6.2, Dump Spots can be set by dozer operators only. Dump Spot requests made by any other machine types are ignored by the office.
The Dump Spotting feature is intended for use by dozer operators working in an area where AMTs dump overburden. The dozer operator can also specify the overburden material to dump on a spot.
Configure Dump Spotting button - Opens the Custom Dump dialog |
Set Dump Spot button - Sets the configured spot for dumping |
Menu - Opens the main menu |
To set a Dump Spot, complete these steps:
- Position and orient the dozer blade on the ground precisely where the AMT needs to dump its load. When created, the Dump Spot will be positioned at the center of the blade on the ground.
- Open the "Custom Dump" dialog using one of the following methods:
Set Dump Spot button - Select the button.
Main menu - Open the main menu and select "Command" > "Dump Spotting" > Set Dump Spot
Note: If pressing the "Set Dump Spot" button the first time since login, the "Custom Dump" menu will open. Refer to "Configuring a Dump Spot".
- An image of a truck with an orange arrow appears on the operator display, showing the dump spot location. The orange arrow indicates the intended direction of the truck. The orientation of the truck image matches the Dump Spot configuration.
- Only one Dump Spot can be set at a time. If a new spot is placed while a previous spot is pending, then the pending spot will be dropped.
- The orange spot arrow automatically disappears after 5 minutes so the plan view is not obstructed. The Dump Spot is still present and the lanes will be displayed.

(1) Load face
(2) 50 degrees |
When setting a spot location, ensure that the spot point is within the limits for the AMT.
Ensure that the spot location conforms to the following:
- Is nominally within ±2 degrees but does not exceed a maximum of -10 percent grade
- Grade is consistent for 1.5 truck lengths into the face or the berm
- Does not cause the AMT bed to contact the face before the tires contact the berm, if applicable
- Does not cause the AMT to pitch more than 10 percent or roll more than 5 percent
- Allows the AMT to approach the berm or the face as close to perpendicular as possible, not exceeding 50 degrees
Refer to Illustration36 and Illustration 37 for more information.
Note: If conditions at the spot location cause the AMT to exceed the pitch and roll limits, the AMT will stop. A greater approach angle will contribute to pitch and roll if the spot location is on a grade.

To erase one spot location, in the main menu select "Command" > "Remove a Spot". The most recent spot that was created by this machine is deleted.
If two spots are present, the "Remove Spot - Double Side Loading" dialog appears. Select the desired remove button to remove the spot, then select "Close" to close the dialog. Alternatively, select "Close" to exit without removing any spots.
Erasing All Current Spot Locations
To erase all current spot locations, in the main menu select "Command" > "Erase Spots". All current spots created by this machine are deleted.
The cusp is the region where the truck turns, just before the truck backs into the spot to be loaded. The cusp connects a spot with a lane. Not all sites will use cusps.
To set a preferred cusp, perform these steps:
- Open the "Custom Loading" dialog.
- Select the spot number, 1 or 2.
- Rotate the heading of the spot, if required. The heading indicates the direction the truck will move away from the spot.
- Select one of the following options:
Use office selection - Fleet office software chooses cusp. This selection is the default.
Required - Operator chooses cusp. Error message if MineStar cannot construct lanes to meet the cusp.
Preferred - Operator selects cusp. MineStar office software constructs lanes to meet cusp or as close to the user-selected cusp as possible.
Ignore office selection - Path planner software chooses cusp. This option is seldom used. See the example below for when to use this option.
Show/hide tableIllustration 40 g06085473 "Cusp Preferences" dialog that appears if the cusp is entered incorrectly - If available, select the cusp as follows:
Left - The cusp region will be to the left of the heading of the spot.
Center - The cusp region will be straight in front of the heading of the spot.
Right - The cusp region will be to the right of the heading of the spot.
Note: The cusp region is always set relative to the spot heading.
If a cusp is entered incorrectly, the following "Cusp Preferences" message as shown in Illustration 40 appears:
Select a cusp option.

Example:
The operator may sometimes have to override the office choice. One example is when the office chooses "Force Left / Force Right", but the planner software cannot comply. In this case, select to "Ignore" the office selection and choose a cusp.
Autonomous trucks cannot detect obstacles that enter the path of travel while traveling in reverse gear. Entering the path of travel of a reversing autonomous truck can result in serious injury or death. Use extreme caution around autonomous trucks operating in reverse and remain a safe distance away from the trucks path of travel. |
NOTICE |
---|
The autonomous mining truck (AMT) cannot detect objects when backing up. When approaching your loader, the AMT expects that you will keep your bucket out of the path of the AMT. Contact with the bucket may damage the equipment. Ensure that your bucket is high enough to dump and will not impede the path of the AMT. |
Depending on the number of spots set up, call a truck to be loaded.
While performing loader operations, create a spot before calling an AMT to load. The loader operator is allowed only one outstanding call for each valid spot. All other call requests are ignored.
Call Truck - Calls a truck to a single-sided loader. |
Note: The loading tool cannot be over the lane when the truck approaches. The truck perception system scans the area when approaching and determines if there are any obstacles preventing the truck from backing in. If an obstacle is detected, the truck will not proceed.
To call a truck to a single-sided loader, complete these steps:
- Ensure that a valid spot location has been set for the position to be loaded. For more information on setting a valid spot location, refer to "Setting a Spot".
- Touch the Call Truck button for the spot to be loaded.
Note: When a call is sent, the tail portion of the green arrow, at the spot location to which the truck will be sent, is transparent. When the request is approved by the system, the tail turns green. If a call is canceled, the tail is transparent.
Note: A second AMT may use the outstanding call to queue at the cusp. The loader may not set a new spot location with a queued truck. The AMT in queue will move into position at the loader without further command.
- The next available AMT will position at the desired spot.
Call Truck to Spot 1 - Calls truck to one side of a double-sided loader |
Call Truck to Spot 2 - Calls truck to other side of a double-sided loader |
To call trucks to both sides of a double-sided loader, complete these steps:
- Ensure that a valid spot location has been set for the desired side to be loaded. For more information on setting a valid spot location, refer to "Setting a Spot".
- Press the Call Truck to Spot 1 button or the Call Truck to Spot 2 button for the side to be loaded. The next available AMT will position at the desired spot.
The Call Truck button is also available. If you use the Call Truck button, select the operation for the button when setting the spot locations. If there is no spot to call the truck into, the truck will be assigned according to the option that is set. Refer to "Calling a Truck".
Note: Do not leave the loading tool in the lane when the truck approaches. The truck perception system scans the area when approaching the loader when traveling in the forward direction and determines if there are any obstacles preventing the truck from backing in. If a loading tool is left in the lane while the truck is approaching, the truck may detect an interference and stop.
- Use the "Waiting Truck" window to check if any trucks are queued for the current spot before setting another spot
Send Truck - Sends the truck at the top of the list in the "Waiting Truck" window |
To send a truck, complete these steps:
- Touch the Send Truck button.
This button sends the AMT that is in the loading state, positioned at the spot location, away from the loader. This action also removes the AMT from the ETA list.
The loaded AMT takes on the next assignment and proceeds to the dump location.
Show/hide tableIllustration 42 g06296786 "Warning" empty truck dialog - If sending the AMT empty, a "Warning" dialog appears confirming that the AMT is to be sent empty.
Press "Cancel" to cancel the send truck command. Press "OK" to send empty. The empty AMT takes on the next assignment.
Cancel Call - Cancels a "Call Truck" request |
Menu - Opens the main menu |
To cancel a "Call Truck" request, complete these steps:
- Access the "Lane Display Options" dialog using one of the following methods:
Cancel Call - Touch the button.
Menu - Open the main menu and select "Command" > "Call Cancel".
Note: Cancel Call does not stop AMTs that have been called to approach the loader and have already passed the queue point.
- Confirm that the Cancel Call is granted by checking the "Waiting Truck" window, if available.
Note: When a call is sent, the tail portion of the green arrow, at the spot location to which the truck will be sent, is transparent. When the request is approved by the system, the tail turns green. If a call is canceled, the tail is transparent.
Occasionally, problems will occur. Good troubleshooting techniques significantly reduce the time required to isolate the problem and, ultimately, reduce the length of downtime. The approach taken to troubleshooting depends on the configuration of the system that is being worked.
The following sections outline some basic troubleshooting strategies when the stated messages appear.
Message | Solution |
---|---|
“A spot location cannot be set. Only set a spot when position status is Fixed, Float, or DGPS.” | Low accuracy means that position status is "Autonomous", "Old GPS", or "No GPS".
Only set a spot when position status is "Fixed", "Float", or "DGPS". |
“The request to set a spot location has timed out. Resend the request, and then contact the office if this request times out. ” | By default the software sends the message five times, and then times out if the office does not reply within 2 seconds.
Resend the request, and then contact the office if this request also times out. |
The office rejected the request to set a spot location. A truck is already moving to this location. | Select "OK". No further action is needed. |

Table 6 outlines the general troubleshooting for cusps:
Trouble | Description | Resolution |
---|---|---|
Selected required cusp. Office removes old lane but does not provide new lane. | Office software fails to set the cusp. May send the following error message: "The office rejected the request to set a spot location. The office cannot find a path to this spot. Contact your supervisor." | Remove the spot and set the spot again. |
Cusps and preferences are not retained over shutdown. | Each time the user reboots the onboard software the user must reset preferences and cusps. This reset is correct functioning. The software retains preferences and cusps when the operator changes, but does not for reboot or shutdown. | NA |
Table 7 outlines the general troubleshooting for Command on Terrain:
Trouble | Description | Resolution |
After Remove Spot, the spot disappears, but the lane remains. | If the network is down and the Remove Spot fails to reach the office, the onboard and office software will be out of synchronization. There is no error message. | Wait until the network is up, then set a new spot. This action causes the onboard and office software to reset. |
After Remove Spot, the spot disappears and the lane may or may not remain. If the operator calls a truck, the call fails (operator message). The Mine Model icon appears on the status bar. | There is a series of messages between the onboard software and the office software. If any message fails, even after the software retries three times, then neither the office nor the onboard have the spot. The lane may, or may not, remain depending on the issue. | Wait for the Mine Model out of Date icon to clear. Ensure that the network is up. |
The Mine Model out of Date icon appears. and Set Spot fails (error message). Call Truck fails but the lane may still appear. | Wait for the Mine Model out of Date icon to clear. Ensure that the network is up and then try Set Spot again. |
Mine Model out of Date - This icon indicates that the mine models updates are out of date. |
