3.3 Status indication
Users can identify the status of robot through the voltmeter, the buzzer and lights mounted on Giraffe.
Status | Description |
---|---|
Current voltage | The current battery voltage can be read from the voltmeter on the rear electrical interface and with an accuracy of 0.1V |
Low voltage alarm | When the battery power is lower than 15% or the voltage is lower than 22V, the car body will emit a harsh sound of "beep-beep-beep" as warning. When it is detected that the battery power is lower than 10% or the voltage is lower than 21V, in order to prevent battery damage, Giraffe will actively cut off the external expansion power supply and driver power supply. At this time, the chassis will not be able to perform motion control and accept external command control |
Power on | TWhen powered on, the buzzer will make a "beep" sound, and the power display module and the screen will light up |
3.2 PS3 controller tutorial
The PS3 handle remote control is an accessory of Giraffe products. Using the PS3 handle can easily control the Giraffe robot. In this product, we use the left-hand throttle design. The functions of the buttons are defined as: the left joystick controls the movement of the chassis, and the right joystick controls the movement of the top servo.
Tutorial:
- Before starting the PS3 controller remote control, you need to insert the receiver into Giraffe's USB port
- Make sure the chassis emergency stop switch is turned on, the emergency stop switch pops up to control mode, press it to enter safe mode
- Press and hold Lai Shida's logo button to power on
- Giraffe runs the chassis driver and the ps3 handle driver (HandsFree WiKi tutorial PS3 control chapter)
- The left joystick controls the movement of the chassis, and the right joystick controls the movement of the top servo

- Make sure that each device has sufficient power.
- Make sure Giraffe does not have any obvious defects.
- Check if the remote controller battery has sufficient power.
3.3.2 Check
- Please charge in time when the device is low battery alarm.
- When Giraffe has a defect, please immediately stop using it to avoid secondary damage.
- When device has had a defect, please contact the relevant technical to deal with it, do not handle the defect by yourself.
3.3.3 Operation
- When using, make sure the emergency stop switch has been released.
- In remote control operation, make sure the area around is relatively spacious.
- Carry out remote control within the range of visibility.
- The maximum load of Giraffe is 20kg, when in use, make sure the payload does not exceed 20kg.
- When installing an external extension on Giraffe, confirm the position of the center of mass of the extension and make sure it is at the center of rotation.
3.3.4 Charging
- Giraffe products are equipped with a charger by default, which can meet the charging needs of customers;
- We recommend that you turn the robot off before charging. And there is no indicator light provided on the site while charging. For specific indicator lights, please refer to the description on the charger.
- Make sure that the Giraffe chassis is in a power-off state;
- Please make sure the main switch is off before charging;
- When charging, make sure the ambient temperature is greater than 0°C;
- Insert the plug of the charger into the charging port of the chassis;
- Connect the charger to power supply and turn on the switch in the charger. Then, the robot enters the charging state;
3.3.5 Maintenance
- According to the IP protection level of the device,please use Giraffe in the environment with the protection level requires for the equipment.

7 Q&A
Q: Giraffe is started up correctly, but why cannot the RC transmitter control the robot body to move?
A: First, check whether the E-stop switches are released; then, check whether the controlmode selected with the top left mode selection switch on the RC transmitter is correct.
Q: Giraffe gives "beep-beep-beep..." sound while running, how to deal with this problem?
A: If Giraffe give this "beep-beep-beep" sound continuously, it means the battery is in the alarm voltage state. Please charge the battery in time.
Q: Why is the Giraffe on but the screen remains black?
A: The shaking during transportation may cause the signal cable to become loose. We recommend that you try pluging the cable back in.
