Rear Panel OverviewRear Panel Overview

Battery Switch​

The Battery Switch is used to cut off the Battery voltage from the robot's electrical circuits. Use this switch for long-time storage and shipping. In the event of a robot malfunction, setting the Battery Switch to the OFF position will turn off the robot immediately, without waiting for the operating system to shutdown.

Battery Switch positionKnob positionPower state
OFFleftbattery disconnected
ONrightbattery connected
DATA LOSS

Cutting off power using the Battery Switch may cause data loss on the Built-in Computer as well as on User Computers.

danger

Cutting off power by putting the Battery Switch in the OFF position is NOT the same as taking out the Battery. When it is necessary to interfere with the internal components of the robot, it is important to remove the Battery from the robot first!

Power Button and Status LED​

Power Button action is triggered with a press and hold of the button for 1 second.

Battery Switch positionRobot statusPower Button action
OFFpowered OFFno action
ONpowered OFFpower ON

The Power Button is equipped with an LED that indicates the robot's status:

LED stateStatus of the robot
ONpowered on
blinkingshutting down
OFFpowered off
SHUTDOWN TIMEOUT

When the Power Button is blinking the shutdown process is ongoing. Normally the button should stop blinking after about 10 to 20 seconds. The robot is waiting for the Built-in Computer to indicate a graceful shutdown. In case of an error of Built-in Computer hardware logic will timeout after 140 seconds and cut off the power anyway.

CONFIGURING GRACEFUL SHUTDOWN

The behavior of the robot after pressing the Power Button can be modified to suit your needs. See Panther Manager for more information.

Emergency Button​

The Emergency Button is connected directly to the Emergency Management Unit, and it is one of the inputs triggering the E-stop signal. Pushing it runs several actions on the robot. There is a possibility to program the behavior of the platform in emergency situations, however, the default actions are:

  • Activate the E-stop signal and latch it.
  • Actively brake the robot using motors.
  • Toggle an SPDT relay (external E-stop output).

You can read more about the E-stop in the chapter Safety.

USB for Gamepad​

There is an EDAC 690-W04-260-014 connector, which provides a direct USB connection to the Built-in Computer. It is dedicated to connecting the Logitech F710 Pad with a modified waterproof USB receiver, but the port can be used to connect any USB 2.0 device to the computer. Information on how to use the Gamepad with the robot can be found in the chapter Controlling Panther Robot.

Charging Socket​

There is a Weipu SP2112/S7 connector mounted on the Rear Deck of the robot with a waterproof cap. The necessary details on charging can be found in the chapter Charging Panther.

Battery & Charging​

Battery​

The Panther power supply is available with a couple of options for easily swappable battery packs. While purchasing the platform, you can choose the basic 720 Wh Battery (BAT01) or the doubled version of 1440 Wh (BAT02). Read more about it in the section Panther Options.

The Battery packs are made of Lithium-Ion cells with a rated voltage of 36 V and 20 Ah or 40 Ah capacity, which gives the Panther enough energy to move around in demanding terrain and perform calculations for about 3.5 hours in the standard version and 7 hours in the doubled version. Moving the robot in friendly terrain allows for a significant extension of the robot's working time, up to 8 hours (standby time up to 40 hours) for the single Battery variant. You can check more specific information about Panther power consumption calculated for the basic version of the Battery.

When the Battery level is low, the Bumper Lights display this status through two distinct animations that are shown periodically. If the Battery level drops below 40% (36 volts), the bumper light displays an animation of two orange stripes moving toward the center. If the Battery level drops below 10% (33 volts), an animation consisting of two red stripes moving towards the center is displayed.

For more information about the Bumper Lights, please see the Panther Lights and Bumper Lights sections, respectively.

Battery Swap​

To remove, insert, or replace the Battery, you require access to the User Compartment. You will learn how to do it in the chapter User Compartment.

The Battery is attached to the inner walls of the robot with DIN 912 M5x12 bolts (4 mm Allen key). After removing the bolts (2 pcs for BAT01 and 4 pcs for BAT02) holding the Battery in place, slide the Battery out of the electrical connector by sliding the package towards the front of the robot by approximately 10 mm. After that, the Battery can be lifted by the handle located on its upper surface.

There are retaining pins pointing out of the Battery, be careful not to damage the seal on the surface of the robot. The Battery is heavy and can damage electronics and wires placed on the User Shelf if not lowered carefully. After lowering (1) the Battery to the bottom of the User Compartment, slide it towards the right side (2) of the robot and then along this wall to the rear (3) of the robot. The locating pins should finally position the Battery, which will slide smoothly into the power socket. The bolts holding the Battery in place should be tightened to a torque of 4 Nm. The steps described above are marked in the figure below.

Charging Panther​

In the set with the robot, we provide a dedicated Charger, which can charge the robot to 80% in 4 hours, and to 100% in 7 hours. The dedicated Charger can be connected directly to the robot's Charging Socket on its housing. There are two types of chargers available. By standard, Panther is shipped with a wired Charger - single or dual (in case of BAT02 option). On the top of these Chargers, there are LED indicators. If all of them are green, that means the Battery is fully charged or not connected. When at least one LED is red, that means the Battery is charging.

Another type of charger is a wireless charger. You can read more about it in the Panther Options section. The wireless charger has also a separate page in manual: Wireless charger.

CHARGING TIME

The charging time for the double Battery (BAT02) should be very close to the single Battery (BAT01). This is possible due to the dedicated Dual Charger for BAT02.

DRIVING THE ROBOT WHILE CHARGING

It is forbidden to drive the robot during the charging process!

MAINTAINING THE LONG BATTERY LIFE

To maintain the long battery life, it is recommended to disconnect the charger after it finishes the charging process (the green LED(s) are ON).

Mounting Rails​

Sensors, equipment, and payloads can be attached to the profiles 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 profile, such as T-nuts, fittings, and angles.

Rails on top of the RobotRails on top of the Robot

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 the User Compartment, top rails can be pivoted by removing 2x shoulder screw M6x30 and 2x DIN 986 M6 nyloc nut in either the front or back. The maximum opening angle is 160 degrees with the 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 the chapter CAD models.

info

The presence of the Mounting Rails has no effect on the water and dust resistance of the robot.

Bumper Lights​

The robot's Bumpers are made of a profile with the same cross-section as the Mounting Rails. They are 0.5 meters wide, and, in addition to buffering shock and reducing potential damage when the robot collides with an obstacle at high speed, sensors can be mounted to them. By default, the signaling lighting is mounted on each Bumper in the form of 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 charge or other detected errors, signal the status of the charging process, or even to illuminate the area in front of the robot. More details regarding Bumper Lights and their control are available in the section Panther Lights.

User Compartment​

The robot's volume has been divided into five parts. The central space, called the User Compartment, is dedicated to the user's components and electronics. The User Computer (for example, PC02 from Panther Options), the RUTX11 router, as well as the robot's Battery are located there.

Access to the User Compartment​

To access the User Compartment, pivot the Mounting Rails by removing 2x ISO 7379 M6x30 shoulder screws with DIN 986 M6 nyloc nuts. Then unscrew the Cover fastened with 8x (IP54) or 18x (IP66) bolts DIN912 M5x12.

caution

To ensure the tightness of the robot, make sure that there are no foreign objects on the seal when assembling the skin element and tighten the bolts with a torque of 4 - 5 Nm.

User Shelf​

The volume of the User Compartment is approximately 13.6 liters (3.6 US gallons) with the BAT01 option or 10.0 liters (2.6 US gallons) with the BAT02 option. This part of the robot has the same water and dust tightness class as the robot. At the bottom of this volume is an easily removable User Shelf to which devices located in this space are attached, excluding the Battery.

User's spaceUser's space

The usable space above the User Shelf is 150 mm high. The top surface of the BAT01 Battery module is 72.5 mm above the User Shelf. The usable space above this Battery is 77.5 mm high. There is no usable space above the Battery when the BAT02 is mounted.

To remove the User Shelf, loosen the DIN912 M5x12 bolts located around its perimeter and move the User Shelf towards the back of the robot, then lift it up. When planning to place components on the User Shelf, keep clearance around the heads of the mounting bolts to allow the User Shelf to be pushed back into place later. Usually, 4 out of 6 bolts are enough to fix the User Shelf properly.

On the front and rear walls of this User Compartment, above the User Shelf, there are connectors that provide power and allow the user to communicate with the robot.

User Power Panel​

The User Power Panel distributes electric power for user applications. The image below shows its labels and arrangement:

User Compartment Front Wall - Power SupplyUser Compartment Front Wall - Power Supply

To meet the user's needs, the robot is equipped with 10 high-current electrical connectors that are able to provide up to 720 W of electrical power to the user's devices. The supply voltages available on the User Power Panel are:

  • 5 V limited to 15 A (3x female XT60),
  • 12 V limited to 25 A (3x female XT60),
  • 19 V limited to 10 A (3x female XT60).
  • AUX Power which is the Battery voltage (32 - 42 V) rated at 10 A max. This output is disabled by default. AUX Power can be enabled and disabled separately from the Built-in Computer via ROS (Service /panther/hardware/aux_power_enable). See section Panther ROS for more details.
TOTAL POWER OUTPUT

The total power from 5 V, 12 V, and 19 V outputs is limited to 360 W of power.

USED CONNECTORS

One 19 V output is used by an optional User Computer and one 12 V output is used by a Router.

These CAD models are applicable to Panther v1.2/v1.21/v1.22 robot revisions.

Software Guide​

Panther is equipped with a Raspberry Pi 4 (Built-in Computer) running a custom Ubuntu-based OS with everything needed for ROS. Each Panther robot includes a microSD card with this OS, which contains drivers for all components.

The primary way to interact with Panther's hardware is via the Robot Operating System (ROS), with all drivers written in ROS. You can find the source code in the GitHub repository husarion/panther_ros. The robot supports both ROS and ROS 2, with similar APIs and behavior.

ROS

ROS is a set of software libraries and tools for building robot applications, offering a common framework for development. It is open-source, making it free to use and modify.

Software Resources​

By default, Panther ROS is deployed using Docker, which simplifies deployment, management, and updates of the ROS system. While the default setup is within a Docker container, you can run Panther ROS drivers natively. Instructions are available on the panther_ros GitHub page.

Autostart Native ROS Driver

Natively built ROS packages do not include autostart functionality. Users need to add it, for example, by creating a systemd service.

The provided Panther ROS system is designed to compose all the basic functionalities of the robot. It allows to control of the robot with velocity commands and provides the user with odometry information, which can be used for robot localization. The Panther ROS system is also designed to monitor the robot's state and perform safety features that will prevent any hazardous behavior. The basic states of the robot are represented by the Bumper Lights signals. This allows the user to recognize if the robot is ready to operate or in E-stop mode, informs about the Battery state, or displays an animation indicating the occurrence of an error in the system. More detailed information about the state of the robot can be acquired using ROS topics. Errors in the system are also logged into the system and can be easily accessed using the Docker interface. The Panther ROS system includes a robot description, which can be used to visualize the robot with all its components.

The Panther ROS system is designed to be easy to use and maintain. It is also designed to be extensible so that it can be easily customized for different applications.

Network​

By default the network mask is 255.255.255.0 and the devices' IPs begin with 10.15.20.XX. The default static IPs are:

  • RUTX11 10.15.20.1 - an internal router with an access point and a DHCP server,
  • Built-in Computer 10.15.20.2 - a SBC with Panther's driver,
  • Additional: User Computer 10.15.20.3 - look at Computer (PC),

Safety​

The robot has been equipped with solutions for the safe use of the equipment, both in the software and hardware layer.

warning

Please take this chapter seriously. Inadequate and irresponsible using of the robot may cause damage to the device, the workplace, and people in the vicinity.

The robot is equipped with an Emergency Management (EMU). It is a system that takes control of the robot's components as well as its power in crisis situations. The EMU can stop the robot's movement, turn off the power of the user's device, or even turn off the entire robot if so configured. It also provides a dedicated electrical User Safety Interface (USI) led out to the User Space.

Due to the appearance of any trigger, such as a Built-in Computer's CPU crash or Emergency Button press, the EMU will call and latch the E-stop signal. This means that in such situations, for the further work of the robot, the problem should be resolved, and then the E-stop latch should be reset.

ADVANCED EMU CONFIGURATION

This chapter describes only the basic default EMU configuration, however, the system is configurable. To learn more about the possibilities and how to configure them, visit a separate article: Emergency Management Unit.

Hardware​

Emergency Button​

On the rear side of the robot, there is a red push button. Pushing the Emergency Button causes:

  • activate the E-stop signal and latch it,
  • actively brake the robot using motors,
  • toggle a SPDT relay (external E-stop output).
ADVANCED EMU CONFIGURATION

These actions are the default EMU configuration. To learn more about the possibilities and how to configure it, visit a separate article: Emergency Management Unit

User Safety Interface (USI)​

USI is an electrical hardware interface for EMU designed to integrate Panther with the user's equipment. This thread is covered in detail in the Emergency Management article in the chapter User Safety Interface.

Transporting Panther​

Panther is shipped in a wooden box for two reasons: to protect the robot itself, and to comply with transportation safety regulations for batteries. Li-Ion batteries with a capacity of over 100 Wh are considered dangerous goods. As long as the product with such a battery is properly packaged and marked, it can be transported by various means, including air transport.

If you consider transporting Panther to a remote location, we recommend that you keep the wooden box with the UN3481 marking and Class 9 (batteries) symbol. You will also need to confirm with your carrier that you are working with dangerous goods. For more details, please contact us on support@husarion.com

Before shipping, disarm Panther by setting all switches to the OFF position and pressing the Emergency Button. Also, the Battery charge level should be below 30% (35V). The tires pressure shall be about 1.5 bar for air transportation and 1 bar for ground/sea transport.
