The Astribot S1 is a humanoid robot from Astribot (Stardust Intelligence), a Chinese company focused on dexterous manipulation. The S1 is notable for its dual-arm manipulation capability — it has drawn attention for demonstration videos showing fast, fluid, human-like handling of objects. Unlike many humanoids that emphasize bipedal walking, the S1 prioritizes dexterity and coordinated dual-arm work, often mounted on a stable base.
Price Range
A robotics aggregator lists an estimate around $99,000 for the Astribot S1; treat this as indicative. The S1 is reported as being in production, targeting service, AI-training, logistics, and research applications.

Model Breakdown
The Astribot S1 is offered as a single dexterous-manipulation platform. Its design priority is coordinated, fast dual-arm manipulation rather than dynamic bipedal locomotion — it is built to perform tasks demanding careful, precise control.
Buyer's Guide: What to Know
The S1 is a manipulation specialist. Its strength is fast, fluid, coordinated dual-arm object handling — it is built for dexterity-demanding tasks, not athletic walking.
The hybrid cable-and-motor drive enables its speed. That transmission design underpins the S1's notably quick, smooth arm motion.
VR demonstration learning is the training method. The S1 learns tasks from human demonstrations via VR — relevant for AI-training and data-collection use cases.
It is a service-and-research robot. Logistics, service automation, and AI training are the intended domains; confirm exact configuration and price directly.
S1 vs Similar Robots
- S1 vs Rainbow Robotics RB-Y1: Both prioritize dual-arm manipulation over bipedal locomotion (the RB-Y1 on a wheeled base).
- S1 vs Figure 02: Both emphasize manipulation; Figure 02 is a full bipedal industrial humanoid, the S1 a manipulation-focused platform.
- S1 vs Astribot's bipedal peers: Within the Chinese humanoid wave, the S1 stands out for treating dexterity — not walking — as the headline capability.
