Still tough! Domestic-made humanoid robots are mischievous and cost under $90,000

Recently, a video of a humanoid robot overcoming obstacles has become very popular

In the video, the humanoid robot successfully passed the obstacle formed by wooden boards and discs

You will stagger if you get kicked, but you won’t fall down

When the load increases to 30kg, the walking speed slows down:

Go up a few steps and then come down one step at a time:

Add some challenges, allowing people to pull forward and push back, and still pass obstacles freely

Finally, perform forward and backward, and you can pass the obstacles under your feet:

This humanoid robot is a well-known robot in China The universal humanoid robot H1 launched by the company Yushu Technology. Compared with the first version released in August, the humanoid robot in this viral video is the latest 2.0 upgraded version launched by Yushu Technology.

In appearance, H1 is about 1.8 meters tall and weighs about 47 kg. Like other independently walking robots, H1 has no face, just sensors and cameras for modeling its surroundings. H1 doesn't have hands yet, and the arms end in small pads.

Due to the M107 joint motor developed internally by Yushu, the robot's dynamic performance has been significantly improved, including movement flexibility, speed, endurance and load capacity. The single leg joint has 5 degrees of freedom, and the single arm joint has 4 degrees of freedom. The walking speed reaches 1.5 meters per second, which is equivalent to the walking speed of an adult. Unlike Asimo's walking posture on stilts in the past, H1's steps are smooth and steady, and it can even run quickly in small steps

##M107 joint motor.

Compared with the Tesla humanoid robot joint motor, the M107 is smaller, lighter and more powerful. The maximum joint torque is 360N.m, which can support the robot to complete more complex actions and adapt to different terrains and walking states, but the weight is only 1.9 kg. Dual encoders are integrated inside the joints of H1. No matter what the initial posture of the robot is, it can resume normal operation at any position and posture, providing a better experience.

Parameter comparison with Tesla humanoid robot joint motor.

The "kick" seen in the video reproduces the "violent" challenge that Boston Dynamics robots faced back then. Although H1 staggered after being kicked, he was still able to move forward quickly. This is worth mentioning

In order to achieve smooth walking and obstacle avoidance, as well as interaction with the environment and users, and complete corresponding tasks, H1 is equipped with a 3D lidar and a depth camera , thus achieving 360-degree panoramic depth perception

The depth camera is very suitable as a sensor for terrain perception and short-range safe obstacle avoidance of legged robots. It uses TOF (time of flight) technology to generate close-range, high-precision three-dimensional point cloud information based on traditional two-dimensional RGB imaging. Combined with attributes such as slope, span height, ruggedness, and the robot's own motion limitations, the robot can immediately Get an accessible map of the area to avoid or overcome obstacles. 3D lidar can realize the construction of dense point cloud maps of the environment, providing a basis for precise interaction between the robot and the environment.

The H1 universal humanoid robot currently sells for less than $90,000, making it relatively affordable for tech company buyers.
