The lockout provides a secondary e-stop for periods during which Husky will be left unattended.
When in lockout mode, the robot will still power on, but the motors will not drive.

Electrical System

Husky is powered by a single 24V sealed lead-acid battery, similar to the type found in electric
wheelchairs, golf carts, and other devices. Husky’s battery is capable of delivering 1800W—
similar to wall mains. This gives Husky’s motors their great performance, however, it is also
enough power to cause severe bodily harm. Please observe the following precautions:



Do not tamper with the plug attached to the battery.



Do not tamper with the fuse panel, except to check and change the fuses, and to connect
and disconnect the battery plug.



Do not operate Husky without the battery door in place. The battery is insufficiently
restrained without the door, and will come loose, damaging the fuse panel.



Charge the battery only with the charger provided by Clearpath Robotics.



Please dispose of the batteries properly, or return the battery to Clearpath Robotics to do
so.

Lifting and Transport

For the safety of users and to maximize the lifetime of Husky, please observe the following
when manually transporting the robot:



Husky should be lifted by two persons, firmly gripping the front and rear bumper-bars. The
battery can be removed to lighten the load of a manual transport.



Ensure that Husky is e-stopped when transporting short distances and powered off when
transporting longer distances.



Note: It is not advised to push Husky, as this can cause damage to the motors

Performance Recommendations

Included in Husky are native software checks and limits to protect the vehicle. However, it is
recommended to monitor the system’s status during usage with

/diagnostics/rqt_robot_moitor

It is also advised to have your software subscribe to the

/husky/data/system_status

topic.

This topic provides useful information regarding voltages, currents and temperatures of the
system in the following form:

Voltages: [battery voltage, left motor driver, right motor driver]

Currents: [total draw, left motor driver current, right motor driver current]

Temperatures: [Left motor driver temp, right motor driver temp, left motor temp, right motor temp]
