The companion remote-control is part of the GO2 remote-control module, which can manipulate GO2 to achieve stable and full control of 3-axis position when standing and to achieve forward and backward movements, turning in place, and other actions on flat ground. It can also activate the intelligent accompanying mode with one click, without the need for remote-control, and enter the autonomous following state. During the forward process, it can intelligently avoid obstacles based on radar data, ensuring the safety of the robot dog and the surrounding environment. The companion remote-control adopts a new buckle design that conforms to ergonomics, making it more secure and comfortable to touch.

Unitree Go2 UWB is a vector positioning module developed by Yushu Technology, which can achieve centimeter level positioning within the plane of the aircraft body. Built in 3-axis accelerometer and 3-axis gyroscope IMU, providing labeled posture. This module is applied to the accompanying functions of Go2 integration and can also be used for user secondary development.

The label joystick belongs to a two axis joystick, and by moving the joystick, the robot can be controlled to move forward and turn. The corresponding relationship between the direction of joystick movement and the direction of robot motion is shown in the following figure.
After Go2 is powered on and stands up automatically, the accompanying remote control can be used. By default, the companion function is disabled, and functions such as joystick control can be used normally. If you need to use the companion function, please follow the procedure below to switch to companion. The specific process is as follows:
Wearing and activating companion mode [Important steps!!!]
Turn obstacle avoidance on/off
