1) Status Indication
Go2's head indicator light can emit different lights to show the current working status of the robot and the
current operating system, please refer to the following table to learn more about the operating status indicated
by different flashing modes and colors:
Color and Flashing
Low flash rate in red
Fast flash rate in red
Permanently on in green
Flash in green
Low flash rate in blue
Low flash rate in yellow
Permanently on in white
2) Intelligent Avoidance
Equipped with Unitree's self-developed 4D LiDAR L1 with 360° × 90° hemispherical ultra-wide-angle perception,
boasting ultra-low blind spot, the minimum detection distance is as low as 0.05m, which can help Go2 to achieve a
blind spot-free coverage, real-time access to three-dimensional information about the surrounding environment, and in
the process of travelling according to the radar data to carry out intelligent avoidance (only support forward obstacle
avoidance), to avoid collision and ensure the safety of the robot and the surrounding environment.
3) Intelligent Side-follow System 2.0 (ISS2.0)
By adopting the new wireless vector positioning and control technology, the positioning accuracy is
technically upgraded by 50%, the remote control distance is over 30m, and combined with the optimised
obstacle avoidance strategy, it can make the robot better traverse complex terrain.
4) Voice Interaction
Supports voice interaction and commands and built-in voice recognition module, and converts human language
into computer language to communicate with the main chip, so as to control the robot and achieve human-machine
language interaction. Reaches voice interaction response at millisecond level, using the industry's advanced voice
recognition technology with high recognition accuracy, fast literacy.
5) App remote image transmission
With the new Unitree Go App, it provides omni-directional ultra-wide image transmission, real-time viewing of
shooting images, built-in 4G and eSIM for more stable connection and remote control. It intelligent OTA upgrades,
which makes the operation in ultra-vision range as simple and convenient as being in the field.
6) Foot Force Sensor
The EDU version features an foot force sensor. The movement of the robot dog will compress the air inside
the foot pad, and transmit the pressure signal to the shoulder force sensor through the air tube, so as to judge
its surroundings, and adjust the movement of the robot dog accordingly.
7) Autonomous Charging
The EDU version supports charging at charging piles. Combined with visual recognition, 3D mapping and other
technologies, it can autonomously plan charging routes and realise autonomous charging, which can provide a strong
guarantee for 24-hour operation.
