Product overview
About Booster K1
The Booster K1 is a 95 cm, 19.5 kg bipedal humanoid from Booster Robotics, positioned as a smaller and lower-cost sibling of the T1 for education, research and competitions. Its product page lists 22 degrees of freedom (2 in the head, 4 per arm and 6 per leg) and a peak joint torque of 60 N·m. Booster launched the K1 at its ecosystem summit and opened sales on 24 October 2025.
Three variants share the same body and differ mainly in onboard AI and battery. The product page rates the Geek at 48 TOPS with 30 minutes of walking runtime, and the Education and Professional at 117 and 200 TOPS with 80 minutes each, measured at 0.4 m/s. Sensors include a stereo depth camera, a 9-axis IMU and a microphone array with speaker. A Doubao large language model is bundled free for six months.
Reported launch pricing in China was a limited-time CNY 29,900. Booster's store page lists the K1 with an inquiry form and no fixed price, so buyers are routed to the company's sales team. Pricing and delivery terms therefore need to be confirmed with Booster.
“Weighs only 19.5 kg, stands 95 cm tall, easy to carry with you!”
