Unitree B2-W Remote Control

User Notice

• Starting from December 2024, the R.l remote control has been fully upgraded to the new R3 remote control. The operation method of the new remote control remains consistent with the old version, ensuring a seamless transition and allowing you to enjoy the convenience brought by the upgrade.
• Both the new and old versions of the remote control will be shipped randomly, please refer to the actual product received. Thank you for your support.

Introduction

The R3 remote control is part of the B2-W remote control module, and the remote control handle is equipped with a digital transmission module and a Bluetooth module. The robot dog and the remote control are bound through the Unitree Explore App, and once successfully bound, they can be connected upon powering on. It can control the robot dog to achieve 3-axis posture and 3-axis position stability when standing, and can also control the robot to move forward, backward, left, right, turn in place, and walk according to certain rules (straight line, circular, linear, rectangular) on flat ground, as well as go up and down slopes/steps. The remote control handle adopts a more ergonomic design for easier grip, providing a more comfortable feel.

Remote Control Handle Rocker Calibration

• Hold the remote control without touching the rocker, press the upper buttons Fl 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—tt sound (l 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—I’ 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.

Remote Control Turn on/Turnoff

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

Vibration/Sound Toggle

• Switching vibration: Quickly press the F3 button 3 times to switch to vibration mode.
• Switch sound: Quickly press the F3 button 3 times to switch to sound mode.

Vibration/Sound Switch

• Turn off vibration/sound: Quickly press the Fl button 3 times to turn off vibration/sound.
• Turn on vibration/sound: Quickly press the Fl button 3 times to turn on vibration/sound.

After modifying the remote control feedback function, it is not saved by default. If you want the changes to  take effect the next time you turn on the remote control, hold the Fl button during shutdmul to save the current mode.

Remote Control Charging

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

• We recommend you to use a 5V/2A USB charger which meets FCC/CE standard.
• Ensure that remote control is switched off before charging it.
• The power indicator light will flash at KHz (l second/time) in charging status and indicate the current power level.
•  When the power indicator light is all on it means the battery pack is full, please remove the charger to finish charging.

R3 Remote Control Basic Operation
For the first time to use remote control, you need to bind it on Unitree Explore 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.

After the remote control is turned on and successfully connected to B2-W, the right DL indicator light will turn on, indicating that the remote control is connected to the B2-W data transmission module. At this point, you can control B2-W using the remote control. When using the remote control to maneuver B2-W with the joysticks, the control methods are as follows:

• Rocker back to center/neutral position: The rocker of the handle is in the middle position.
• Rocker amount: The deviation ofthe remote control rocker from the center of the rocker.
• 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.

Remote Control Instructions

• Stand-up recovery safety instructions: The stand-up recovery function requires space for flipping over. There : should be no people or objects within a 3-meter radius around the robot dog to avoid unnecessary personal injury and property damage. Othenyise, Unitree Robotics will not be liable for any resulting losses or  consequences.
• For the forward jump function, please access the Unitree Explore App to trigger it. The forward jump function is considered a dangerous action. When activated, ensure that there are no obstacles within a semicircle with a 4-meter diameter in front of B2-W (especially no people). If non-standard operations cause personal injury.
• If the R3 remote control is not connected to the robot dog or phone after turning on, it will automatically shut within 10 minutes if there is no operation. If you need to connect and use it, please turn it on again.
