Unitree G1 Humanoid Robot Jumps and Punches in Human Training Demo

January 21, 2026

Unitree Robotics recently shared a video of their G1 humanoid robot jumping and executing punches during a training session alongside a human trainer. Priced from around $13,500 (approximately 200万円), this compact machine showcases athletic feats like a 1.4-meter broad jump, fueling talks of household potential while raising safety flags in close-quarters demos.¹ Replies to the post affirm the footage is genuine, though some note the robot's head design feels off-putting, and others hail its sci-fi caliber athleticism.

Unitree Robotics and the G1 Launch

Unitree Robotics, a Chinese company, develops high-performance humanoid robots such as the G1 for research, education, and light industrial tasks.² The G1 debuted in May 2024 as a smaller counterpart to the company's taller H1 model standing at 180 cm.⁸ Available via distributors like RobotShop and TechShare, it starts at $13.5K, making advanced humanoid tech more accessible.¹

The G1 measures 127-132 cm tall, 450 mm wide, 200 mm deep, and weighs about 35 kg.² Its basic configuration offers 23 degrees of freedom — six per leg, one at the waist, and five per arm — upgradable to 43-45 joint motors.¹ Knee joints deliver up to 90 N·m torque in base form or 120 N·m enhanced, with arms handling 2-3 kg loads.⁶

Technical Foundations

G1 employs force-position hybrid control paired with a dual encoder system for precise motion and balance.¹ Joints use low-inertia, high-speed PMSM motors with internal rotors for quick response and efficient heat management.⁶ Large joint ranges include waist Z-axis at ±155°, knees from 0-165°, and hips with pitch ±154°.¹

Sensors comprise a depth camera like the D435i, 3D LiDAR such as LIVOX MID360 for 360° mapping, plus a multi-mic array and speaker.² Computing power comes from options like NVIDIA Jetson Orin modules for real-time AI tasks.² The Unitree Robot Unified Large Model (UnifoLM) drives advanced control and operations.⁵

Impressive Demonstrations

Recent footage captures the 132 cm G1 leaping 1.4 meters broad — a standout for its size.⁴ A kickboxing demo pits two G1 units in a ring, trading punches and kicks with agility from secondary development and imitation learning; they sport faceguards and gloves.⁵ Basic moves include walking, turning, sitting, standing, squatting, waving, and voice responses in English or Chinese.¹

Body twists and splits highlight the joint motors' flexibility.⁵ The training video emphasizes human-robot collaboration, with the G1 matching human punches and jumps fluidly. Observers note its mind-blowing prowess evokes sci-fi, though the head design on related models draws mixed aesthetics feedback.

Practical Applications and Gaps

G1 suits research, education, prototyping, and dynamic light industrial work.² It supports secondary development via imitation and reinforcement learning to hone skills, ideal for algorithm testing and environmental adaptation.² Leg length totals 0.6 m, arm span 0.45 m, enabling human-like reach.⁶ From a practical view, it navigates warehouse floors well, but lacks dexterous hands for final manipulation tasks — the last mile of value.dexterous hands

Safety and Comparisons

While athletic demos impress, close human proximity in training raises flags on collision risks and control reliability. The G1's compact form aids home use prospects, but safeguards need bolstering for real-world deployment. Compared to Unitree's H1, the G1 prioritizes affordability over height at 127-132 cm.⁸

Paths Forward / Looking Ahead

The G1-D wheeled variant signals Unitree's push into data collection and AI training, blending mobility with intelligence.⁵ Ongoing UnifoLM integration promises smoother operations across varied settings, from labs to factories. Developers can leverage its open platform for custom behaviors, accelerating adoption in education and prototyping where cost barriers once loomed large.

As humanoid preformance scales — think fleets in warehouses or homes — hand dexterity emerges as the pivotal upgrade, unlocking chores like folding laundry or precise assembly. Safety protocols must evolve alongside, embedding fail-safes in dynamic environments to mitigate mishaps seen in early demos. Unitree's trajectory positions the G1 lineage as a benchmark for affordable, capable robotics, urging competitors to match on price and agility.
