Overview

Unlike traditional wheeled and tracked inspection robots, quadruped robots feature discrete footholds for adapting to different terrains—stairs, slopes, steps, and mountains, among others. Quadruped robots have GPS, lidar, robotic arms, testing equipment, and other instruments, which allow them to complete a variety of work—from surveying, search and rescue, and security patrol to intelligent construction and more. They also provide various work and services, like patrol inspection, material transportation, and exploration, for electric power, petrochemical, mineral collection, and railway.

Unitree Robotics has introduced consumer-level quadruped robots—the Go1 series. Among the series is the mid-range Go1 Pro, which boasts 3 processors, 5 depth cameras, a side-follow system, and adaptive joints.

Design

Go1 Pro measures 645 × 280 × 400mm at stand position and 540 × 290 × 130mm when folded. It weighs 12kg and has a payload weight of 3kg. Sloped at 35 degrees, it has a maximum speed of 3.5m/s.  The processor includes a built-in AI 16-core CPU plus a 384-core, and the GPU is of 1.5TFLOPS type.

Joints & Motors

The joints exhibit a 12 degree of freedom, increasing stability, especially when moving through stairs. The Body/Thigh Joint Motor design can adapt to various mechanical equipment as it can achieve an instantaneous torque of 23.7 N·m. Meanwhile, the Knee Joint has a 35.55 N·m instantaneous torque.

The low-noise and lightweight yet durable power joints require no wires since the motors already connect joints seamlessly to the body. The industrial grade cross roller bearing contradicts the axial impact for extremely high precision. There is also a patented heat dissipation system built around the knee joint motor. Lastly, the Omnidirectional flexible buffer structure acts as an impact absorber, freeing the device from injury when dropped 1.5m high.

Sensory System - Stereo Depth Cameras & Voice Module

Creating the omniscient view of the robot are 5 stereo depth fish-eye cameras. These cameras work together to capture the view, which is accessible in the mobile app Unitree Robotics Go1. AI post-processing is also available, along with 3 sets of hypersonic sensors with 150 x 170° lens angle. The voice module functions act like a walkie-talkie linking the robot's surroundings and the controller. It also paves the way for receiving audio data from areas that are unfit for human exploration. The same app, Unitree Robotics Go1, allows this communication feature.

Battery

Go1 Pro has a lithium-ion power cell with a 6000mAh capacity and an endurance time of 1-2.5 hours—enough to meet every need of the robot’s routine operation. The battery management system (BMS) keeps track of the battery status, ensuring a stable and safe operation.

Intelligent Side-follow System

Go1 Pro adopts the patented wireless vector control and positioning technology. It walks alongside a human, positioned across the lateral peripheral vision for harmonious and safe human-machine interaction. The robot acts respectively on the user's position and obstacles. The side-follow system helps the robot choose better routes, especially in complex environments.

APP Top View

Aside from an omnidirectional view, Go1 Pro’s ultra-wide angle video image transmission gives users a view of the surrounding terrain—leading to a simple and convenient operation as if being present on the scene.

Software

A user PC will directly connect Go1 Pro with Ethernet, controlled by the airborne dual master and the bottom controller. The open high-level control is capable of sending high-level motion commands, like forward, backward, left, and right movement to the robot. Developers also have the convenient visual perception call mode for possible secondary development. The open-bottom control reads and controls every robot motor and sensor. Combined with low-delay data and image transmission, the robot can realize mutual data transmission in real time.
