A training session involving Unitree’s G1 humanoid robot has gone viral for all the wrong—and funny—reasons. The clip, first uploaded to China’s Bilibili on December 25, shows a human trainer controlling the G1 using a motion-capture suit. The setup allows the robot to mirror the trainer’s movements in real time, a common method used to teach humanoid robots complex actions.

Things are going smoothly at first. The trainer throws a few punches and kicks, and the G1 follows along without issue. But during one sequence, the robot appears to misjudge a rotation and delivers a kick straight into the trainer’s groin.

The reaction is immediate. The trainer doubles over, clutching himself before dropping to his knees. Seconds later, the robot copies the same posture, bending forward as if reacting to the pain itself—a moment that has turned the clip into a meme across social platforms.

The video quickly spread beyond Bilibili, appearing on X (formerly Twitter) the next day. It was shared widely, including by Tesla Cybertruck chief engineer Wes Morrill, and has since picked up traction on Reddit and other forums.

The humanoid robot has previously been shown playing table tennis, shooting basketballs, and performing martial arts routines. This incident, however, highlights one of the risks of close-range teleoperation, where small timing errors or misread movements can lead to unexpected results.

Despite the mishap, teleoperation remains an important tool for training humanoid robots, especially for tasks that are too complex to pre-program. Still, the clip serves as a reminder that even advanced robots are far from flawless.

For now, the G1’s accidental kick—and its perfectly timed imitation of human suffering—has given the internet a good laugh.

The post Humanoid robot’s hilarious mishap goes viral: kicks trainer and mimics the pain appeared first on Gizmochina.

Unitree Robotics has officially introduced the G1-D, its first wheeled humanoid robot designed for advanced data collection and model training. The robot serves as the centerpiece of a full-stack solution that combines high-performance humanoid hardware with a scalable software platform for data acquisition, AI training, and real-world deployment.

Specifications

The G1-D is available in two versions: Standard and Flagship. Both models stand between 1260 mm and 1680 mm tall and weigh up to 80 kg. The Standard version is stationary, while the Flagship version features a mobile base that supports differential drive and can move at speeds of up to 1.5 meters per second. The mobile base includes sensors such as LiDAR, depth cameras, and collision detection units.

Unitree has equipped the G1-D with 17 degrees of freedom on the Standard model and 19 on the Flagship model, excluding the end effectors. Each arm has seven degrees of freedom and supports a payload of up to 3 kg. The robot’s waist joint allows motion along the Z-axis up to ±155 degrees and along the Y-axis between -2.5 and +135 degrees. The platform supports a vertical working range of 0 to 2 meters.

The robot features a high-definition binocular camera on its head and an additional HD camera on each wrist. It supports various end effectors, including a two-finger gripper, three-finger dexterous hands with or without tactile sensors, and a five-finger dexterous hand. Unitree has powered the G1-D with an Nvidia Jetson Orin NX module that delivers up to 100 TOPS of AI performance. The Flagship version offers a battery life of up to six hours.

The G1-D is designed for a wide range of real-world applications. It can perform repetitive manual tasks in industrial and service environments, assist in warehouse automation, collect and annotate data for AI training, and even interact with retail or consumer settings using its onboard vision and mobility. The robot’s dexterous hands and mobile base allow it to manipulate objects, conduct inspections, or serve as a data-gathering agent in complex environments.

Alongside the hardware, Unitree has launched a comprehensive software stack that manages the entire AI workflow. This includes data acquisition tools, task management, annotation systems, and real-time tracking. The platform supports distributed training and integrates with popular open-source frameworks such as GROOT and PI. It also includes a simulation environment for model evaluation and supports seamless export and deployment of trained models.

In related news, Alibaba has recently unveiled its first self-developed AI glasses featuring swappable batteries, a POV camera, and the Qwen assistant. Meanwhile, an LSE study predicts that by 2028, Gen Alpha will rely on voice rather than keyboards at work.

The post Unitree launches its first wheeled humanoid robot that can see, grip, and learn appeared first on Gizmochina.

Robots are not new, they are here since the last decade, and we are talking about them for the last many years. However, now they are more advanced thanks to the evolving technology and continuous research. Many new countries have now become part of the robotics revolution in industrial, farming, and various other sectors. Different robots specializing in different aspects are now becoming a reality. Similarly, a Chinese robotics company Unitree has unveiled a new four-legged robot dog. Unitree A1 resembles the features of Boston Dynamic’s robots and is available for under $10k.

Unitree A1 is a fully functional four-legged robotic dog debuted earlier this year at Consumer Electronics Show (CES) 2020. It is robust and can perform jumps, flips, and can travel ten feet or seven miles per hour. The strong motor and flexible joints are some primary reasons behind such rapid actions.  The robot features different sensors assisting it efficient in decision making.

The primary features include excellent performance, and speed while maintaining stability. It features a multi eye intelligent depth camera for better precision and supports Real-Time HD Video transmission. Moreover, it can follow any human being with any issue assisted by dynamic obstacle avoidance. The robot can even understand gesture recognition.

Technical Aspects of Unitree A1 Robot

Unitree A1 has a payload capacity of 5KG, 1-2.5 hours of endurance time along 2 protection modes. It uses 2 real-time operating systems to efficiently run without any issue. There are 4-foot pressure sensors making itself walk reliably, efficiently, and conveniently.

4X Electric Motors Specifications

The robot packs 4X Electric Motors producing joint torque of 22.5nm, and maximum joint velocity of 21 rad/second. It can be quickly assembled without any major maintenance. Each motor can work separately in a different position, speed, and torque.
