Best practices and general tips for smooth operation
MARC products were designed to take extremely complex technology and make it simple.
Mapping tips:
•
When mapping a n
ew area (Active Map Mode), it is beneficial to ‘close the loop’ and
return to the same point
mapping began. This allows for a more accurate map.
MARC’s software will be able to reference that initial point to
straighten any areas that may have shifted during the mapping process.
•
When initially mapping an area (Active Map Mode) and planning to save the map (Fixed Map Mode) for use in a
single area, it is best not to have temporary objects in the area. Once the map is saved, those temporary items will
be part of the permanent map. This may include, but not limited to, pallets of good, parked or stationary forklifts,
moveable staircases, similar large items, and people walking near the cart.
•
When in Active Map Mode, be sure not to push MARC at speeds greater than 1.5m/sec (5mph) to avoid gaps in the
map creation.
•
When pushing the cart in Active Map Mode, only push from the handle side. Pushing from other sides can cause
lower sensor visibility and result in a reduced quality map.
•
When setting destinations, position the cart at least 1m (3 feet) away from any obstacle. This will generally prevent
an abandoned route when returning to that destination.
•
Never manually move or push the cart while it is moving autonomously, as this can cause the wheels to slip and
thus interfere with the mapping process.
General tips:
•
If you are using MARC in a specific area (in Fixed Map Mode), it is important not to move MARC outside of that
area. You may want to include a ‘parking spot’ for MARC in the initial mapping to
have a consistent place to put
MARC when temporarily not in use.
•
When in Fixed Map Mode, MARC should not be moved when powered down, as this may cause confusion when the
unit is powered back on. This includes during powered-off storage, battery swapping or any other time the unit is
powered off or the battery is removed or turned off.
•
The area where MARC units are stored should have fixed objects nearby. Since the cart needs to recognize where it
is, if the environment has changed while the cart was turned off or rebooted, it may become confused.
•
When transporting heavy payloads, the cart may coast a short distance while coming to a stop.
•
In large open areas the cart may become disorientated. This may present itself as abandoned route or the cart
pausing. Returning the cart to an area with distinct obstacles will allow the cart to orientate itself.
•
Well defined areas include multiple distinct fixed objects, for example an inner walled corner or permanent
shelving. More fixed objects will result in better results.
•
In order to match and navigate a mapped area, the cart will need to identify objects nearby. It may require
less than 10 feet (3 meters) of distance between the cart and multiple fixed objects to properly orient itself.
Large, open areas do not
provide sufficient data to recognize its surroundings.
