Congratulations – and thank you! MARC® is made by the highly experienced team at MūL Technologies® – manufacturers who want to bring autonomous mobile robots (AMR) that make practical sense to warehousing, manufacturing and logistics companies. MūL Technologies’ approach to AMR is different: We take commercial off-the- shelf (COTS) components and add minimum custom hardware to create intelligence/movement.

7. Verify the Emergency Stop button (#4 above left) is not engaged. This can be found at the front of the cart (the end away from the handle). If engaged, turn the button in the direction of the arrows to reset – the button will pop out when disengaged.
Programming your first destinations Now that you’re ready to roll, let’s give MARC a try! 1. If cart is booted up and ready, go to step 5. 2. Turn the key switch to ON position. 3. Press power button. If the cart does not power up, verify the emergency stop button is not engaged and disengage if needed (rotate clockwise with arrows until it pops out).
EZ-Go Navigation system overview First (main) screen Second (extended) screen Station buttons 1-13 display in grey when they are not programmed for a specific destination. Press and hold a grey button until you hear the double-beep indication (approximately 3 seconds) to program that station with the unit’s current location.

To turn Looping Mode on, press and hold the Looping Mode button for 3 seconds till you hear the double- beep tone. The icon will turn green to indicate is has been activated. To turn looping mode off, press and hold the button for more than 6 seconds until the triple-beep sound is heard.
Operating modes: Active Map and Fixed Map modes MARC carts operate in two distinct mapping modes. It is important to understand the differences between these modes to ensure the most value for your unique scenario. Below is a comparison chart, followed by an overview of each mode. Depending on how you plan to use each MARC, you have options to most efficiently leverage the benefits of automation that will help save you the most time possible.
Using MARC in Active Map Mode MARC defaults to Active Map Mode from the factory and is indicated by the Save Map button appearing grey. Active Map Mode will remain in effect until the Save Map button is used to save a map. This results in the mode of operation moving from Active Map Mode to Fixed Map Mode.
Operating modes: Looping Mode MARC carts can operate in a mode where it moves from location to location automatically. In this mode, all preprogrammed destinations are shown in blue. The cart will move through all locations in sequential order without user intervention.
Using the Home Button On occasion, like any autonomous robot, MūL robotic carts can become disoriented. This typically happens because of carts being moved while they are powered off – mapping cannot be done while power is off or the battery removed, and the cart is not actively mapping.
What to expect during normal operation MARC products were designed to take extremely complex technology and make it simple. The simplicity allows users to easily and quickly engage the use of these carts and speed adoption. This will help MARC products offer an ROI at a much quicker pace.
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 new area (Active Map Mode), it is beneficial to ‘close the loop’ and return to the same point mapping began.
Powered manual movement mode ❶ ❷ All safety features are disabled while using the powered manual movement mode. Operator is responsible for safe movement of MARC in powered manual movement mode. Great care must be taken while using powered manual movement mode. Powered Manual Movement mode allows the user to control the cart motion manually if needed.
Adjusting the volume ❶ ❷ Users can control the cart volume for audio cues. To access the volume adjustments, press the battery level indicator button (❶) from the main screen. Tap the volume (+) button to increase the volume. The current volume level is indicated in small text at the bottom of the button.
Using MARC battery packs Lithium-ion battery packs may get hot, explode or ignite and cause serious injury if they are abused electrically or mechanically. Observe the following precautions when handling using and storing lithium-ion batteries: • Never leave power on to battery when not in use. •...
Charging the batteries MūL Technologies battery packs and chargers are designed for use in MARC products exclusively. The battery packs are designed to offer many hours of service and have a charging life of over 800 cycles. The charging port cover rotates to open. Lifting the cover too high may result in damage.
Locking and unlocking battery packs Using the keyed battery switch: Indicates the battery pack is ready for removal or insertion. No power is supplied in this position and the battery slides freely into the battery bracket. NOTE: To move from unlocked position to “Locked with power off” position, it is important to push the key inward and then release slowly while turning the key to the next position.
Inserting the battery pack into MARC To insert a battery pack into MARC, follow these steps: Make sure battery is charged. You can check this by pressing the button on the battery level indicator. • o See Charging the batteries on page 29. •...
Loading MARC safely Important loading guidelines: • Total load should not exceed: o 250 pounds / 110 kilograms during autonomous operation. o 500 pounds / 225 kilograms during powered manual push mode. • Tall loads may strike low hanging objects above or become unstable and tip.

Cleaning MARC MARC systems are made from an extremely durable polypropylene material that will not leak, rust, chip, dent or peel, and will maintain a professional appearance for many years. The RCP unit (drive system) is made from very thick, strong powder coated steel enclosure to ensure protection of the electronics.
Troubleshooting Problem Things to try After rebooting MARC, my In Active Map Mode, this is by design; MARC does not retain maps or preprogramed destinations are gone, locations when powered down. Since programming is extremely easy, and the buttons appear grey. simply manually push MARC on the next route and reprogram the destinations.
