The current version is aimed mainly at research and AI data collection.","sections":[{"h":"What it is","p":["Astribot was founded in Shenzhen in December 2022. It calls its approach \"Design for AI\" (DFAI): hardware and software designed together so the robot is well suited to data collection and model training. S1 is its first product.","Unlike bipedal humanoids, S1 has a human-like torso, head and two arms but moves on a mobile base. Astribot itself describes it, in the Lumo-1 write-up, as \"a bimanual mobile manipulator with human-like dexterity and agility\"."]},{"h":"Hardware","p":["Astribot's spec table lists S1 at 170 cm and 80 kg with a 194 cm arm span. Each arm has 7 DoF and lifts 5 kg at horizontal reach. The end effector reaches at least 10 m/s and about 100 m/s² acceleration, with ±0.1 mm positioning repeatability. Astribot compares this with an adult man (5-10 m/s in an arm swing, ±1-5 mm accuracy).","The robot runs 4-6 hours on battery and can also work plugged in. Astribot notes that the figures are for the research version and some can be unlocked for higher performance. The 10 m/s figure is arm-tip speed, not driving speed."]},{"h":"Software and AI","p":["S1 ships with APIs, developer guides, a visual development interface, support for major simulators and a full pipeline from data collection to model deployment. Data can be recorded through VR teleoperation.","Astribot develops its own models. Lumo-1 combines vision-language reasoning with physical action, trained in three stages (continued VLM pre-training, co-training on cross-embodiment robot data, and action training on trajectories collected on S1), followed by reinforcement learning. The company also publishes Lumo-2, Philia and SmoothRL."]},{"h":"Use cases and price","p":["Astribot targets universities and research institutes, companies building robot AI models and data-collection centres, with industry and home use as longer-term goals. It does not publish a price or sales numbers."]}],"timeline":[["2022-12","Astribot founded in Shenzhen."]],"faq":[["How fast is Astribot S1?","Its end effector moves at 10 m/s or more; that is hand speed, not driving speed."],["How much does Astribot S1 weigh?","80 kg at 170 cm, according to Astribot."],["Does Astribot S1 walk?","No, it moves on a mobile base, with a human-like torso and two arms."],["How much does Astribot S1 cost?","No price is published."]],"sources":[{"title":"Astribot S1 product page and specifications","publisher":"Astribot","url":"https://www.astribot.com/en/product","date":"2026-10"},{"title":"Astribot home page (About)","publisher":"Astribot","url":"https://www.astribot.com/en","date":"2026-10"},{"title":"Lumo-1","publisher":"Astribot","url":"https://www.astribot.com/en/AI/Lumo1","date":"2026"}],"updated":"2026-10-10"},"mera":{"rental_with_operator":false,"sale_in_offer":false,"availability":"confirmation_required","shop_url":null},"url":"https://merarobotics.com/blog/humanoids/astribot-s1","inquiry_url":"https://merarobotics.com/en/start?service=purchase&robot=astribot-s1"}
