How big are humanoid robots?

Built around human height

Most full-size humanoids stand between 150 and 185 cm. That is deliberate: a robot meant to work in a warehouse, factory or home has to reach the same shelves, open the same doors and use the same tools as the people who work there. 13 of the 59 full-size robots we track are taller than a 175 cm adult.

Smaller robots trade reach for safety and price

Robots around 120 to 140 cm, such as the Unitree G1, are lighter, cheaper and safer to fall over. They suit research labs, education and demos more than lifting work. Tabletop robots are smaller still and mainly serve as developer kits.

How to read the chart

All figures share one floor and one scale, set by the tallest figure on screen. Photo cut-outs come from the robot's best full-body image and are scaled head to feet. Robots without a clean full-body photo appear as grey silhouettes at their exact height. Use the link button to share a lineup; the link keeps the robots, the human height and the units.

Humanoid robot size FAQ

answers from sourced data

What is the tallest humanoid robot?

Dexmate Vega by Dexmate is the tallest humanoid robot we track at 220 cm (7 ft 3 in), weighing 135 kg (298 lb). Next comes HMND 01 at 220 cm (7 ft 3 in).

How tall is the average humanoid robot?

Across 59 full-size humanoids with a published height, the median is 170 cm (5 ft 7 in). Makers design most of them around human height so they fit doorways, stairs, workbenches and shelves built for people. 13 of them are taller than a 175 cm adult.

How tall is Tesla Optimus?

Tesla Optimus Gen 2 / v2.5 by Tesla stands 173 cm (5 ft 8 in) tall and weighs 57 kg (126 lb). That is about the height of an average adult man.

How tall is Figure 03?

Figure 03 by Figure AI stands 173 cm (5 ft 8 in) tall and weighs 61 kg (134 lb). That is about the height of an average adult man.

How tall is the Unitree G1?

Unitree G1 by Unitree Robotics stands 132 cm (4 ft 4 in) tall and weighs 35 kg (77 lb). That is 43 cm shorter than a 175 cm adult.

How tall is the Unitree H1?

Unitree H1 by Unitree Robotics stands 180 cm (5 ft 11 in) tall and weighs 47 kg (104 lb). That is 5 cm taller than a 175 cm adult.

How tall is 1X NEO?

1X NEO by 1X Technologies stands 168 cm (5 ft 6 in) tall and weighs 29.9 kg (66 lb). That is 7 cm shorter than a 175 cm adult.

How tall is Boston Dynamics Atlas?

Boston Dynamics Electric Atlas by Boston Dynamics stands 190 cm (6 ft 3 in) tall and weighs 90 kg (198 lb). That is 15 cm taller than a 175 cm adult.

How tall is Agility Digit?

Digit by Agility Robotics stands 175 cm (5 ft 9 in) tall and weighs 65 kg (143 lb). That is about the height of an average adult man.

What is the smallest humanoid robot?

Among walking humanoids, NAO by Aldebaran is the smallest we track at 58 cm (1 ft 11 in). Small humanoids like this are mostly used for research, education and robot soccer, where low weight makes falls cheap.

What is the heaviest humanoid robot?

HMND 01 is the heaviest humanoid with a published weight at 300 kg (661 lb). Heavier robots usually carry bigger batteries and stronger actuators for industrial payloads.

How is this size comparison drawn?

Every figure is scaled from the robot's published height, the same way as the human reference. Where we have a clean full-body photo (9 robots), we cut the robot out and scale it head to feet; otherwise we draw a neutral silhouette at the correct height. Poses differ between photos, so treat small differences of a few centimetres with care.
