Changelog

Added to the census.

Scope correction. The census adds only robots a buyer can acquire now (on sale, pre-order, contact-to-order or active crowdfunding); a listed robot that is later discontinued stays, marked retired. ASIMO, Phoenix and GR-2 were added already retired, never qualified, and have been removed. Their earlier changelog entries stay.

Correction to today's scope note. The census lists robots that exist, on sale or not, so prototypes and concepts may be added. Only a product already retired or discontinued before we listed it is never added; a listed robot its maker later withdraws is kept and marked retired.

Added to the census.

Active DoF (Total) corrected from 33 to 31 on official spec page

Added to the census.

Battery runtime is now one row on robot pages and /compare. Robots whose maker publishes a runtime range (or one figure per usage mode) show it there, in hours, instead of under a separate "Battery life" row; no figure changed.

Spec fields that described one concept under two names are now one row each on robot pages and /compare — Dimensions (all in mm), Max joint torque, Range, Weight, Payload and Deposit. Published weight and payload ranges now sit in the Weight and Payload rows, and the AiNex's 21 cm/s walking speed joins the walking-speed row as 0.76 km/h. No figure changed.

More spec fields consolidated, one row per concept — Onboard compute (the robot's own computer; compute performance in TOPS and expansion sockets have their own rows) and a single set of load rows (Payload, Max standing load, Max load, Peak payload, Arm payload, Lift capacity), now stored as numbers. Kit-edition weights live in the Models line. No figure changed.

Added published figures from the spec page — standing size 820 × 430 × 570 mm, unloaded range 15 km

Commercial → discontinued, confirmed by ROBOTIS. No current price.

Battery runtime marked as a maximum — AgiBot states "up to 10 hours"

Degrees of freedom marked as a minimum — AgiBot states "40+"

Generation clarified — figures describe the deployed generation (payload 35 lb, battery 4 h, from Agility's 2026-09-03 page, no longer published); Digit 5, in development, added to Models with Agility's preliminary estimates

Max speed marked as a minimum — EngineAI states "≥2m/s"

Battery runtime marked as a maximum — Hiwonder states "up to 60 minutes"

Degrees of freedom changed from 31 to 33 — the spec page states "Active DoF (Total) 33" (31 body joints plus 2 gripper DoF); the overview page's "up to 31 DoF" counts body joints only

Weight, height and battery runtime marked as maximums — LimX states "≤20kg", "≤…845mm" and "≤2h"

Sale price reduced from $599.00 to $479.20

Battery runtime marked as a maximum — MAB states "up to 2 hours"

Generation clarified — price and specs describe 4NE1 Gen 3.5 (on reservation); Gen 4, unveiled 2026-10-22, added to Models with specs and price not yet published

Added to the census.

Weight marked as a maximum — Pollen states "under 800 g", an upper bound, not a measured weight

Payload and range marked as minimums — RIVR states "over 30 kg" and "over 30 km"

Battery runtime marked as a minimum — Unitree states ">5 hours"

Stair height marked as a maximum — Unitree states "up to 25cm"

Payload and running speed marked as minimums — Unitree states "> 40kg" and "> 6m/s"

Standard Kit with Raspberry Pi 5 (8GB) price reduced from $589.99 to $560.99

Price reduced from $519.99 to $467.99 (10% discount, $52.00 savings)

Max speed added — 2 m/s walking (7.2 km/h), from the rebuilt official page.

Max peak joint torque added — 60 N·m.

Edition battery figures updated to the rebuilt page — Geek 2 Ah / 20 min, Education and Professional 5 Ah / 1 h 10 min walking runtime.

Sale ended; price changed from $459.99 to $519.99

Payload range revised from 10-100 kg to 10-20 kg

Max speed now records the walking figure, 1.4 m/s (5.0 km/h); the max run speed, 6.2 m/s (22.3 km/h), is recorded separately.

Official spec: 31 active degrees of freedom

Max speed recorded as the walking figure, 1.8 m/s (6.5 km/h); the maker's running speed, 5 m/s (18 km/h), is recorded separately.

Max speed (2.7 km/h) labelled as a walking figure.

No legged speed is published, so max speed is now empty; the 5 m/s (18 km/h) lab-tested maximum is recorded as rolling speed.

Max speed (8.64 km/h) labelled as a sprint figure, as the maker states it.

Max speed (9 km/h) labelled as a running figure.

Max speed now records the fastest speed on legs, under 1 m/s (3.6 km/h, walking); the wheeled-mode figure, up to 3 m/s (10.8 km/h), is recorded separately as rolling speed.

Builder price changed from $144 to $154 (KS Late Pledge, after the Kickstarter campaign funded successfully)

No legged speed is published, so max speed is now empty; the 14 km/h maximum is recorded as rolling speed.

Max speed (21.6 km/h) labelled as a running figure.

Max speed is now empty — Unitree publishes no rated speed for the H1 (only a 3.3 m/s world-record run, kept in the record's notes); the "<2 m/s" figure on the spec page belongs to the H1-2.

Max speed (6 km/h) labelled as a running figure.
