MetaLimbs
Research on controlling additional robotic limbs through leg and foot movement
Keep in mind Historical research prototype; no production or present retail availability inferred.
Compare wearables
Compare up to 10 devices across categories. Keep the purpose and the source beside the numbers.
How price order works
Lowest recorded store prices take priority over announced or launch prices, within the selected source market. Currencies use the dated EUR reference rates. Deposits and recurring charges are excluded from price order; missing prices stay last. Original price records remain visible.

Battery claims use different conditions and are not a controlled benchmark. “Not verified” is an evidence gap, not a missing feature. Prices are dated regional snapshots. Deposits, bundles and historical launch prices are labelled. Brightness measurement methods and battery workloads vary by manufacturer.
