Introduction

The handheld remote control is part of the Go2 remote control module, and the remote control handle has a installed digital transmission module and a bluetooth module. The robot dog communicates with the remote control through the data transmission module. The robot dog can be manipulated to achieve stable and full control of 3-axis posture and 3-axis position when standing. The users can manipulate the robot to move forward and backward, move left and right, spin turn and walk under certain rules (straight line, circle, rectangle), etc. on flat ground, and can even climb or walk downstairs and slopes. The remote control handle adopts a easy holding design, which makes the structure conform with ergonomic and feels more comfortable.

Handheld Remote Control Handle Rocker Calibration

Hold the remote control without touching the rocker, press the upper buttons F1 and F3 on the remote control and release them at the same time. At this time, the remote control will emit a continuous “beep~beep~” sound (1 time/sec) to indicate that it has entered the calibration mode. After entering the calibration mode, the users need to turn the left and right rockers to full rudder and rotate several times until the sound of “beep~beep~” stops, and the calibration is ready. Press F3 once to make the calibration take effect and complete the calibration.

Attention! When calibrating the remote rod, please do not touch the rocker before calibration. The rocker can only be moved after entering the calibration mode.

Handheld Remote Control Turnon/Turnoff

Turn on the handheld remote control: Shortly press the power button once, then long press the power button for more than 2 seconds, and hear a “beep”, which means the remote control is turned on.
Turn off the handheld remote control: Shortly press the power button once, then long press the power button for more than 2 seconds, and hear three “beeps”, which means the remote control is turned off.

Handheld Remote Control Charging

When the handheld remote control battery indicator shows low power, the handheld remote control should be connected to the charger, as shown in the figure below:

Charging

a) We recommend you to use a 5V/1A USB charger which meets FCC/CE standard.
b) Ensure that handheld remote control is switched off before charging it.
c) The power indicator light will flash at 1Hz (1 second/time) in charging status and indicate the current power level.
d) When the power indicator light is all off it means the battery pack is full, please remove the charger to finish charging.

Handheld Remote Control Basic Operation

For the first time to use handheld remote control, you need to bind it on Unitree Go App, [Settings] -> [Remote Control Settings] – turn on the remote control switch, enter the corresponding remote control code, and then you can bind it with the digital transmission module on the robot dog.

Basic Operation

The digital signal lights on the left side of the two-handed remote control are all on, which means that the connection is successful. Then you can use the remote control to control the robot dog to complete the corresponding action. When the handheld remote control is used to control Go2, the control mode of the rocker is divided into standing control and walking control.

Standing control

Walking Control

a) Rocker back to center/neutral position: The rocker of the handle is in the middle position.
b) Rocker amount: The deviation of the remote control rocker from the center of the rocker.
c) Walls, doors, and other obstacles greatly weaken the signal between the robot and the remote control module. Please be sure to operate the robot in an open space.
