AgileX Hunter 2.0

This guide provides essential information for getting started with the AgileX Hunter 2.0.

Pre-requisites

Before operating the Hunter 2.0, ensure you have:

• Completed safety training (see General Safety)

• Access to the robot’s CAN interface

• A compatible RC transmitter (if using remote control)

• Adequate workspace with proper clearance

Robot App

The Hunter 2.0 supports development via CAN bus interface. AgileX provides:

• Open-source SDK

• C++ and ROS packages

• CAN bus protocol documentation

Robot Webserver

If configured with an onboard computer, the robot may have a web interface accessible via the robot’s IP address.

Charging Robot

The Hunter 2.0 is equipped with a 10A charger by default.

Charging Procedure:

1. Ensure the Hunter 2.0 chassis is powered off (Q3 switch in OFF position)

2. Connect the charger plug to the Q6 charging interface on the rear panel

3. Plug the charger into a power outlet and turn on the charger switch

Charging Times:

• 30Ah Battery: Approximately 3-4 hours

• 60Ah Battery: Approximately 6-7 hours

Battery Voltage Levels:

• Fully charged: ~26.8 V

• Normal operating: 24-26.8 V

• Low battery warning: < 24.5 V

• Critical (auto-shutdown): < 24.0 V

Warning

Always monitor the charger and battery during charging for safety. Do not charge in temperatures outside -10°C to 40°C range.

Charging Controller

The battery charging status should be monitored via the charger’s own status LED. The chassis does not have a dedicated charging indicator light.

Emergency Stop

The Hunter 2.0 has an emergency stop button located on top of the chassis.

Activating Emergency Stop:

• Press the red emergency stop button to immediately halt all movement

• The robot will engage the parking brake automatically

Resetting Emergency Stop:

1. Twist the emergency stop button clockwise to release it

2. Reset the SWA switch on the RC transmitter before movement is possible

Power On

Pre-Startup Checks:

• Inspect the robot for any visible damage

• Ensure both emergency stop buttons are released

• Check that the Q3 drive power switch on the rear panel is not pressed down

Startup Procedure:

1. Press the Q3 button to turn on the chassis

2. The voltmeter should display the battery voltage (normal: 24-26.8 V)

3. Both front and rear lights should illuminate

4. If the beeper emits continuous warnings, the battery is low - charge before use

Power Off

1. Press Q3 to cut off power supply

2. Wait for all lights to extinguish

3. For extended storage, ensure the battery is charged to at least 50%

Basic Operation

Remote Control

Setup:

1. Ensure the chassis is powered on

2. Turn on the RC transmitter (press and hold POWER button)

3. Move SWB switch to remote control mode (middle position)

4. Release parking with SWA switch (up position)

Controller Mapping:

Network Interface

CAN Bus Connection:

The Hunter 2.0 uses CAN bus for communication. Connect via the USB-to-CAN module:

1. Connect the USB-to-CAN adapter to your computer

2. Connect the CAN interface to the robot’s expansion port

3. Configure CAN interface:

   sudo ip link set can0 up type can bitrate 500000
   

4. Verify connection:

   candump can0
   

SSH Connection (if onboard computer is installed):

1. Connect to the robot’s network

2. SSH to the robot:

   ssh user@<robot_ip>
   

First Test

1. Power on the robot following the Power On procedure

2. Turn on the RC transmitter

3. Set SWB to remote control mode

4. Release parking (SWA up)

5. Gently push S1 forward to move the robot

6. Test steering with S2

7. Engage parking (SWA down) when finished
