Precautions
OperationPrecautions
Ensure that the surrounding area is relatively open when operating the RANGER.
Please do remote control within sight.
The maximum load of the RANGER MINI 2.0is 80 KG. Please ensure that the payload does not
exceed 80 KG when using.
When installingexternal equipment on the RANGERMINI 2.0, Please ensure theircentroid
location is at the RANGERMINI 2.0
’
scenter of rotation.
Please charge the RANGER MINI 2.0in time after low-battery alarm.
When the RANGER MINI 2.0is abnormal, please stop using it immediately to avoid secondary
injury.
When the RANGER MINI 2.0is abnormal, please contact the technical support immediately,
and do not handle it without professional suggestion.
Please use the RANGER MINI 2.0in an environment that does not exceed itsIP protection level.
Do not push the RANGER MINI 2.0directly.
The current of the tail extension power supply does not exceed 15A, and the total power does
not exceed 720w.
Battery
The battery of RANGER MINI products is not fully charged when it leaves the factory. The
specific battery voltage and power can be displayed through vol and batt on the RANGER MINI
remote control.
Please do not charge the battery after it is exhausted, please charge it in time when the low
battery of the RANGERMINI remote control is less than 15%
Static storage conditions: The optimal storage temperature is -10℃~40℃. When the battery is
not in use, it must be charged and discharged once every month, and then stored at full
voltage. Do not store the battery Place in fire, or heat the battery. Do not store batteries at high
temperatures.
Charging: You must use the matching lithium battery charger for charging. Do not charge the
battery below 0°C. Do not use non-original standard batteries, power supplies, and chargers.

The RANGER MINI 2.0is a programmable omnidirectional UGV (UNMANNED GROUND VEHICLE),
which is a chassis with a modular design. Compared with the four-wheel differential chassis, the
RANGER MINI 2.0has obvious advantages when running on ordinary cement roadsand asphalt
roads. It not only has higher speed and load capacity, but also reduces the wear and tear on the
structure and tires. Itis also more stable and safer. Compared with Ackermann chassis,the
RANGER MINI2.0 not only reduces the turning radius, but also can turn at 0 angle.The RANGER
MINI 2.0combines the advantages of differential chassis and Ackermann chassis, which is
suitable for various complex terrains. What
’
smore, it can be equipped with stereo cameras,
LiDAR, GNSS, IMU, manipulators and other equipment to beapplied in fields such as unmanned
inspection, security, scientific research, exploration and logistics.
