CHAPTER 1. MPO-700

1.4. TRANSPORT

Fig. 5: Gripping areas of the MPO-700

1.4.4 Long Distance Transport

As long as the robot is packed properly there are no special requirements when shipping the MPO-700. Only in case
the robot has been exposed to very low temperatures (below -10°C) it should be left to reach room temperature again
before turning it on. This will prevent damages to the electrical and electronic components.

1.4.5 Shipping with AGM Battery

If the key switch was removed there is no risk of the robot being turned on during the transport or the battery being
discharged.

Tip:

To eliminate every risk when shipping the robot as airfreight it is recommended to disconnect the battery prior

to shipping. The AGM batteries are leak-proof and approved for airfreight.

1.4.6 Shipping with LiFePO4 Battery

Due to safety regulations any shipment of a lithium based battery has to follow certain procedures.

Please contact Neobotix if you plan to ship a robot with LiFePO4 battery.
