Product Page

Astribot S1 is the product of Shenzhen's Astribot, marketed as an AI robotic partner rather than as a machine, and the company's pitch rests on a single unusual claim: that it is the first to mass-produce tendon-driven AI robots. The centrepiece of the product page is not a feature list but a comparison table that sets S1 against a normal adult male, and it wins nearly every row. It has 7 degrees of freedom per arm, matching the human reference, and carries 5 kg per arm at horizontal reach where the comparison puts people at 3 to 5 kg. Its end effector reaches at least 10 metres per second against a human 5 to 10, and accelerates at about 100 metres per second squared against 50 to 100. Its positioning repeatability is plus or minus 0.1 mm, an order of magnitude tighter than the plus or minus 1 to 5 mm given for a person. It stands 170 cm and weighs 80 kg, so it is slightly shorter and notably heavier than the 173 cm and 70 kg reference. The company reads that table as S1 mirroring an adult male's operational parameters, with the performance, stability and safety to let researchers and explorers bring their ideas to life. Underneath sits the architecture the company calls Design for AI, a software-hardware integrated system that couples AI capability with what it calls optimal operation, and which it credits with a breakthrough in embodied intelligence data acquisition so the robot can learn, think and work much like a person, interact fluently and use human tools. Its AI models are documented separately as Lumo 1, Lumo 2, Philia and SmoothRL, with S1 as the body that puts them to work.
