Safety Instructions

Go2 is a globally high-performance, consumer-grade interactive quadruped robot that requires practice to master the skills of manipulation.

1. This product is not a toy and is not intended for use by persons under the age of 14. Keep out of reach of children and be careful when operating in the presence of children.

2. It is your responsibility to be aware of the laws in your area and to comply with them.

3. This chapter is an introductory chapter for new users to manipulate robots. New users can quickly master how to use the handle to control the robot to show excellent movement performance by reading this section.

4. Do not lift the robot after it is powered up to avoid the robot performing unanticipated actions that could cause damage to itself!

5. Go2 is a purely electric quadruped robot with certain anti-jamming, but the energy density of the motor is much lower than the hydraulic pressure. Do not push the robot suddenly and vigorously, nor to kick the robot, so if the robot falls and is damaged due to a sudden and strong push or kick, it will not be covered by the warranty.

6. Robot dog mounted with devices like docking station and LIDAR is prohibited to do side rolling. Side rolling can only be done in case there are no external devices on the back of the robot dog.

Requiring Environment:

1. Please do not run the robot in an electromagnetic interference environment. Sources of electromagnetic interference include but are not limited to: high-voltage power lines, high-voltage transmission stations, mobile phone base stations, and television broadcast towers.

2. Please do not run the robot in the Wi-Fi signal interference environment. Wi-Fi signal interference is usually caused by co-channel interference. In case of interference, be sure to turn off some or all Wi-Fi signal sources of other wireless devices before using the remote control to operate the robot.

3. Please keep it under control in the users' view when using the robot and keep the robot maintain a safe distance of at least 2 meters from obstacles, complex ground, crowds, water, and other objects.

4. Run the robot in $ 5^{\circ} $C -35°C with good weather condition. Do not run in inclement weather, such as fog, snow, rain, lightning, sandstorms, windstorms, tornado weather, etc.

5. The robot is not waterproof, so do not run it with water on the ground, in rain, snow, or wet conditions! The robot is not dustproof, please do not run it on gravel floors, dusty environments!

6. The legged robot has certain requirements for the ground on which it walks. Do not use the robot on very low friction ground, such as ice. Do not use the robot on soft ground, such as thick spongy ground. If the robot is used on smooth ground, such as glass and ceramic tile, the users need to control the robot for movement carefully and smoothly, avoid violent movement, and reduce the walking speed of the robot to prevent the robot foot from slipping and falling.

Understanding Your Go2

Introduction

Unitree's new upgrade interactive bionic quadruped robot Go2 has 12 degrees of freedom (composed of 12 aluminium alloy precision joint motors), and employs force-control technology to provide composite control of force and position for each joint, in order to achieve force-control of the whole machine to achieve excellent motion performance. The whole robot is made of aluminium alloy and high-strength engineering plastics, which greatly improves the stability and reliability of the machine dog; the maximum running speed can reach 5m/s (measured in the laboratory). Equipped with 4D LIDAR L1 with $ 360^{\circ} \times 90^{\circ} $ hemispherical super wide-angle sensing, which can help Go2 to achieve no blind area coverage. It reaches the leading level at home and abroad both in terms of structure, motion performance, environment perception, and side following.
