How to read this comparison
This comparison is prepared by MALONI, which offers robotics services and may have commercial relationships with some listed manufacturers. We disclose these relationships; technical information and ordering follow the same methodology.
Alphabetical order by manufacturer, model and variant. No overall score. Services and commercial relationships do not confer a technical advantage.
A manufacturer statement is not an independent physical test. Video does not establish autonomy or operational reliability. A MALONI MuJoCo simulation is not a physical robot test.
Autonomy requires evidence for a specific task, environment, operator interventions and software version. Missing data is not zero or “no”. Conflicting values are excluded from filters.
Prices and availability require review after 30 days, other parameters after 90 days. Overdue values are marked; overdue prices are excluded from budget filters. Budgets are compared in the same currency without automatic conversion.
“From” prices are lower bounds, not total deployment quotations. Authorization, warranty repairs, stocked parts and response times require separate evidence.
The technical table separates weight without hands from weight including the battery, single-arm load from two-arm handling, and walking runtime from standing. Ah and Wh, or TOPS and TFLOPS, are not directly compared. Dimensions retain the manufacturer’s axis order.
The owner confirmed manufacturer image permission for the MALONI website on 21 October 2026. Every image has a source credit. An image shows a particular configuration or demonstration; it does not establish another configuration’s contents or autonomy.
