  1. This product is not a toy and is not intended for use by persons under the age of 18. Keep out of reach of children and be careful when operating in the presence of children.

  2. You are obliged to be aware of the laws in your area and to comply with relevant laws and regulations.

  3. This chapter is an introductory chapter for new users to manipulate robots. New users can quickly master how to use the Remote Control to control the robot to show excellent movement performance by reading this section. This chapter is also a chapter that old users often need to refer to. Old users can read this chapter repeatedly to grasp the essentials of operating the robot, and then they can draw inferences from case, and know what kind of movements are not recommended.

  4. When the users run the program developed by themselves in the developer mode: The remote-control commands are still valid when the high-level (application layer) is developed. At this time, if the high-level API commands and the remote-control commands are sent to the robot, both commands will be executed by the robot. It may cause the robot to become unstable. Please be sure to judge whether the users need to use the remote control according to the running state of the robot. Remote control commands fail during low-level development.

  5. When using, please control the robot within sight, keep a certain safe distance from the robot, and do not touch the robot with your hands after the robot is powered on.

  6. When using complex remote-control commands, such as forward jumping, please make sure that there are no obstacles (especially people) within a half-circle with a diameter of 4 meters in front of the robot dog.

    If any casualties or property damage occur due to non-standard operations, Unitree Robotics will not be responsible for any resulting losses and consequences!

  7. Safety reminder for restoring standing position: Restoring standing position requires space for the robot dog to flip over. Please ensure that there are no people or objects within a 2-meter diameter circle around the robot dog to avoid unnecessary casualties and property damage. Otherwise, Unitree Robotics will not be responsible for any resulting losses and consequences.

  8. When the battery power is only one block left, please stop and turn off the robot dog in time, take out the battery to charge to avoid the damage of falling when the battery is low.

1. Operation Environment Requirement

  1. Run the robot in -20 degree C -55 degree C with good weather condition. Do not operate in bad weather, such as lightning and tornado weather. When operating in water, the users need to be sure to comply with the requirements described in the IP67 Protection level instructions.
  2. Please keep it under control in the users' view when using the robot and keep the robot maintain a safe distance of at least 3 meters from obstacles, complex ground, crowds, water, and other objects.
  3. Do not operate the robot in electromagnetic interference environments. Electromagnetic interference sources include but are not limited to high-voltage power lines, high-voltage substations, cellular telephone towers, and television broadcast towers.
  4. 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 turn off some or all Wi-Fi signal sources of other wireless devices before using the remote control to operate the robot.
  5. Due to varying levels of operational proficiency among personnel, for reliable and safe operation, please use the robot in open, unobstructed, and flat ground environments. When operating the robot, note that steps must be lower than 20cm and slopes less than 20°. Failure to meet these conditions may cause the robot to fall. When the robot walks on complex terrain with uneven surfaces or inclines, operators should reduce its walking speed and maneuver cautiously to prevent tripping over obstacles.
  6. Legged robots have specific ground requirements. Do not use the robot on surfaces with extremely low friction, such as ice. Avoid using it on soft ground, including thick sponge surfaces. When operating on smooth surfaces like glass or tiles, please control the robot's movements gently and smoothly, avoid abrupt motions, and reduce its walking speed to prevent foot slipping and potential falls.
