Power supply

The Panther is equipped with a set of battery cells in Lithium-Ion technology with a rated voltage of 36V and 20Ah, which gives it 720Wh of energy to use for calculations and move around in demanding terrain for about 3.5 hours. Moving the robot in a friendly terrain allows for a significant extension of the robot's working time up to 8 hours (standby time up to 40 hours). You can check more specific information about Panther power consumption here.

Low battery level will be indicated by a change in the bumper light - both lights will fade in and out orange to indicate that the battery voltage has dropped below 35 volts. Read more in the Bumpers and signal lights section.

To meet the user's needs, the robot is equipped with 9 high-power electrical connectors that are able to provide a total of 505W of power to the user's devices. The supply voltages available on the user Power panel are 5V with a total current limitation up to 15A (3x female XT60), 12V limited to 20A (3x female XT60) and 19V limited to 10A (3x female XT60).

Note: *Each of the voltage sources has an independent overcurrent switch, but the total power consumed by the devices plugged into the Power panel cannot exceed 360W.

Charging Panther

In the set with the robot, we provide a dedicated 42V @ 5A charger, which the robot will charge to 80% in 4 hours, and to 100% in 7 hours. The mains-operated charger is connected directly to the robot's charging connector on its housing.

Warning! It is highly recommended not to use the robot during the charging process! When the charger is connected to the robot, the robot should be turned off completely.

Warning! Please do not leave charger connected to the robot after the charging process is completed (the red LED and charger fan will turn off).

Mounting rails

Sensors, constructions and payload can be attached to the profiles on top of the robot.

Rails on top of the RobotRails on top of the Robot

The profiles used are aluminum V-slot 2020 profiles. The best way to attach the elements to them is to use mounting elements dedicated to this type of profiles, such as T-nuts, fittings and angles.

V-slot aluminum extrusionV-slot aluminum extrusion

These profiles are fixed to the robot with four ISO 7379 M6x30 shoulder screws with DIN 986 M6 nyloc nuts.

Top rails fixingTop rails fixing

To enable access to user space, top rails can be pivoted by removing 2x shoulder screw M6x30 and 2x DIN 986 M6 nyloc nut in either to the front or back. Maximum opening angle is 160 degrees with built-in stop.

Top rails openTop rails open

For more useful information in the field of mechanics, please see the document Panther Overall Dimensions and chapter CAD models.

Note The presence of railings has no effect on the water and dust resistance of the robot.

Bumpers and signal lights

The robot's bumpers are made of a profile with the same cross-section as the railings. They are 0.5 meters wide and, in addition to buffer shock and reducing potential damage when the robot collides with an obstacle at high speed, additional sensors can be mounted on them. By default, the signaling lighting is mounted on each bumper in the form of an aluminum profiles with 46 programmable RGB LEDs.

These lights may be widely used - to indicate the status of the robot, the direction of movement or the intention to change direction, warn about low battery or other detected errors, signal the status of the charging process or even for illuminate the area in front of the robot. More details regarding lights and their control is available in ROS API section.

Access to the interior

The robot's volume has been divided into three parts. The central space is dedicated to the user's components and electronics. Here, by default, the Inter NUC computer, RUTX11 router and the robot's battery are located. Two user panels has been led to this space. A panel distributing electric power for the user:

User Panel - Power SupplyUser Panel - Power Supply

And a panel for communication with the rest of the robot - as standard it is an Ethernet connector to the internal SBC):

User Panel - Communication PortUser Panel - Communication Port

The front and rear spaces are occupied by motors and built-in electronics. For these spaces it is usually not needed to access by the user. Opening these spaces is mainly used for service work.

To access the components inside the user space, pivot the top rails by removing 2x shoulder screw and 2x nyloc nut. Then unscrew Cover (18x DIN912 M5x12).

The bolts must be re-tightened with a torque of 4-5 Nm.

Warning! A necessary condition to meet the protection rate for external conditions and the faultless operation of the robot is lack of foreign objects on the seal.

Warning! A necessary condition to meet the protection rate for external conditions and the faultless operation of the robot is the correct tightening of all screws fixing the Cover and both Decks!

Space inside the robot

Inside the robot, there is a dedicated volume of approximately 14.5 liters (3.8 gallons) for the user's equipment and devices. This part of the robot has the same water and dust tightness class as the robot. By default, there is the Intel NUC on-board computer and the RUTx11 router responsible for both the communication of the robot with the inner world and the connection of computers and sensors within the robot.

Data frequency is 1Hz and can be interacted ether with GPSD daemon (gpsd -N udp:// or directly with ROS package redirecting signal to ROS topic.

After cloning this package [IMPORTANT: use branch decode-udp-line] into your workspace (~/husarion_ws/src) use following command to run:

rosrun nmea_navsat_driver nmea_socket_driver _port:=5000 _local_ip:=

or use launch file:

<arg name="port" default="5000" />
<arg name="local_ip" default="" />

<node pkg="nmea_navsat_driver" type="nmea_socket_driver" name="nmea_socket_driver_node" output="screen">
<param name="port" type="int" value="$(arg port)"/>
<param name="local_ip" type="str" value="$(arg local_ip)" />

You should be able to see data on /fix topic (rostopic echo /fix).

Lights pattern could be set by calling appropriate message to /set_panther_lights service, to change animation to BLINKER_LEFT:

rosservice call /set_panther_lights "animation: 1
custom_color: ''"

To change animation to BLINKER_LEFT with custom colors (front is green, rear is red):

rosservice call /set_panther_lights "animation: 1
custom_color: '0x00FF00 0xFF0000'"

More details regarding lights control could be found in panther_lights documentation.

More details regarding driver could be found in panther_driver documentation.

Disable autostart ROS nodes

Brand new Panther launches some ROS nodes, you can disable them just by sending systemctl commands.


By default roscore starts at main computer and can be disabled by logging (default ssh husarion@ pass:husarion) and executing following command:

systemctl disable roscore.service


Panther driver starts at RPI SBC and it's responsible for controlling motors, and also sync time from main computer it's not recommended to disable this because you can end up with timestamp problems. Instead we recommend to customize launch file by setting appropriate arguments. If you still want to disable this use:

sudo systemctl disable launch_driver.service
