Astribot S1 Clocks 120 Slices per Minute in High Speed Kitchen Knife Prep Trials
- The Astribot S1 achieved cutting speeds of 120 slices per minute during kitchen trials.
- The robot processed 50 kilograms of produce with strict sub-millimetre slice uniformity.
- Visual and tactile sensors provide instant halt protocols if human hands enter the cutting zone.
- Make & Model / Release Finding: Astribot S1 leads this culinary capability, with expected rollout to early adopters by early 2027.

The Astribot S1 has achieved a major milestone in kitchen automation by mastering high-speed culinary knife prep. During extensive benchmark testing, the robot managed an impressive 120 slices per minute. It processed 50 kilograms of varied produce while maintaining strict sub-millimetre uniformity across every slice. This level of speed and consistency is a massive leap forward for humanoid robots operating in dynamic kitchen environments.
Stardust Intelligence equipped the S1 with rapid visual processing algorithms and highly responsive force-torque sensors. These systems work together to ensure blade safety and consistent thickness, regardless of the vegetable's texture. The robot securely grips round items like onions and tomatoes with one hand while the primary operating arm executes rapid chopping motions. If the visual sensors detect a slip or an unexpected hand entering the workspace, the cutting mechanism halts instantly to guarantee total kitchen safety.
The implications for both residential households and commercial kitchens are enormous. The S1 robot successfully standardises meal prep, removing the tedious burden of slicing and dicing from human cooks. Families can enjoy perfectly prepared ingredients in a fraction of the time, knowing the hardware operates with safety limits that far exceed human reaction times.
Astribot S1 in Action: High-Speed Culinary & Domestic Manipulation

Automating knife prep removes one of the most time-consuming and accident-prone tasks in cooking. This allows families to cook fresh meals faster while eliminating the risk of accidental finger cuts.
Always supply the robot with sharp, high-quality chef knives to ensure clean cuts and reduce unnecessary mechanical strain.
At a 40-hour workweek (173.33 hrs/mo), running this 15-minute task on 1X NEO Beta costs $0.73 per task ($2.93/hr on Factory RaaS) or $0.71 per task ($2.83/hr on a 48-mo 7.9% APR loan).
Humanoid robots are highly safe and fast at cutting vegetables. The Astribot S1 by Stardust Intelligence recently validated its kitchen knife prep capabilities by slicing 120 cuts per minute with sub-millimetre uniformity. It features instant safety halt protocols to stop the blade immediately if humans get too close.

Q: Is it safe for a robot to use a kitchen knife?
Yes, models like the Astribot S1 use rapid visual processing to track their environment. If a human hand enters the safety zone, the robot stops cutting instantly.
Q: How fast can humanoid robots chop vegetables?
Recent benchmarks show robots like the Astribot S1 can achieve 120 slices per minute, matching or exceeding typical human kitchen prep speeds.
