Assembly

Receive the Crate1

The robot arrives in one wooden crate, approximately 58" x 68" x 60" and 1,800 lbs. Use a forklift or pallet jack to move the crate to a level surface with adequate space on all sides.

The cables, bolts, battery retention brackets and neck close-out plate needed for setup are packed inside the crate.

Open the Crate2

Using a power drill, unscrew the lid first, then the four walls. Keep all fasteners and panels; they are reusable for return shipment.

Release the Straps3

The robot is strapped down at its four corners to eyebolts in the pallet floor. Release the ratchet straps and keep them for reuse.

Remove the Robot from the Pallet4

If batteries are installed, the robot can be driven off the pallet. If the robot arrived without batteries, it cannot be driven and must be lifted off the pallet with suitable lifting equipment before battery installation. Never attempt to lift the robot by hand.

Inspect the Folded Neck1

The neck is folded down for shipping and the sensors are covered with protective wrapping. Remove the wrapping and note how the neck is folded.

The neck pivots on an M10 x 140mm partially threaded hinge bolt running horizontally through the neck. This bolt is loosened at the factory to allow the neck to rotate. Confirm it is loose before raising the neck.

Raise the Neck2

Raising the neck is a one-person lift, but a second person may assist if the position is awkward. Stand on the bed and hold both sides of the headlight and sensor plate.

As you raise the neck, pull it toward the rear of the robot. The pivot sits in a slot and will bind if you do not pull rearward while lifting.

Sweep the neck up in one continuous motion. Stop and assess if you feel any resistance or see a cable snag. A second person watching the cables is helpful.

The neck is fully raised when it is vertical and the tab is flush with the dashboard.

Secure the Front Bolt3

Install the M10 x 25mm bolt through the tab into the dashboard and tighten with a 17mm socket. Torque to 32 ft-lb.

Lift the Bed4

Flip up the bed to expose the mounting holes on the neck and dashboard. The neck will still move slightly with only the front bolt installed.

Install the Close-Out Plate5

Position the close-out plate (supplied) over the rear of the neck. Confirm all cables run cleanly in the neck channel and cannot be pinched by the plate, bolts or structure.

Loosely install all 10 M10 x 25mm bolts (supplied), then tighten in a star pattern so the plate clamps down evenly. Torque to 32 ft-lb.

Tighten the Hinge Bolt6

Tighten the M10 x 140mm hinge bolt, holding the head and nut with 17mm sockets. Torque to 32 ft-lb.

Check the Neck7

Push on the front of the neck. It should show minimal movement. Check the hinge bolt torque monthly to keep the neck rigid.

Stowing the Neck for Transport8

If the robot needs to be shipped again, loosen the bolts from the steps above and reverse the raising procedure. Pull the neck rearward as you lower it and check that no cables are pinched, especially around the pivot.

Before You Start1

The standard Grande 44 uses two 48V 100Ah Lithium Iron Phosphate (LFP) batteries (10 kWh), installed side by side in the two lower battery bays: one under the power enclosure and one under the compute enclosure. Robots shipped within North America typically arrive with batteries installed; if so, skip to Final Connections and Verification.

For international shipments, the batteries arrive in a separate shipment from the battery manufacturer. Read and follow the Quick Start Guide supplied with the batteries.

Make sure the robot is powered OFF. Wear insulating gloves when working on battery terminals. Each battery weighs approximately 82 lbs; use two people to lift batteries into the chassis.

Prepare the Batteries2

Remove and discard the two protective caps from each battery's terminals. Using the terminal screws supplied in the battery packaging (in a pocket in the top foam), attach the on-battery cable to each battery. One battery receives the on-battery disconnect cable and the other receives the standard on-battery cable.

Connect red to the positive (+) terminal and black to the negative (-) terminal. Torque each terminal screw to 12–14 N·m (106–124 in-lb) with a 13mm socket. Take care not to short across the terminals.

Place the insulating boots over the terminals and zip-tie each boot securely to its cable. Set a top hold-down bracket on each battery.

Open the Bed3

Release both bed latches using the white handles at the front left and front right of the robot. Lift the bed completely; a kickstand will drop into place and hold the bed up so you can work safely underneath.

Raise the Power Enclosure4

The power enclosure is hinged along one side and held closed by a rotary latch. Pull the release loop at the front of the power enclosure (it comes up from the chassis below the enclosure) to release the latch, then lift the enclosure. When it is fully raised, a spring plunger engages and holds the enclosure up.

Watch the cables at the hinge as the enclosure rises. Stop if any cable is pulled tight or caught.

Install the Compute-Side Battery5

With two people, lower the first battery into the opening under the raised power enclosure, then slide it sideways into the bay under the compute enclosure. Secure its hold-down bracket.

Install the Power-Side Battery6

Lower the second battery into the bay under the power enclosure and secure its hold-down bracket.

Check Battery Voltages7

Measure the voltage of each battery with a multimeter. The two readings must be within ±0.2 V of each other. If the difference is larger, charge the lower battery to match before connecting them, or a large current surge will occur.

Connect the Jumper Cables8

Connect the between-battery jumper cables to the yellow Anderson connectors on each battery.

Lower the Power Enclosure9

Confirm no cables are pinched, chafed or compressed, especially at the hinge and around the latch. Disengage the spring plunger to release the enclosure, then lower it slowly until the rotary latch engages with a click. Keep fingers clear of the edges while lowering.

Tug up on the enclosure to confirm it is latched. Do not operate the robot unless the power enclosure is fully latched.

Close the Bed10

Lift the kickstand to release it, then lower the bed using the handle on the side of the robot. Keep your hand on the handle; do not place your hand above or forward of the handle, as it can pinch your fingers. Lock both bed latches.

Connect Batteries to the Robot1

Connect the battery harness to the power enclosure.

Initial Power On2

Turn the red power switch to the ON position.

Verify Software3

Once the UI loads, navigate to Settings > General. In the side menu, verify that the software version is labeled “Production”.

NTRIP Setup4

Contact Burro support at support@burro.ai to enable NTRIP credentials for the machine.

Battery Calibration & Charge5

To calibrate the battery level, the robot needs to be fully charged. Plug the robot in overnight to ensure the battery charge level is calibrated before use - the battery percentage shown initially WILL BE incorrect
