BODY · JOINTS · SUPPLY CHAIN

Fonta Robotics builds the whole solution behind a robot.

Body, joints and supply chain, for model companies and robot makers — sourced globally, integrated, delivered as product. Below: who makes the parts, what they cost, and who is buying.

BILL OF MATERIALS · READ THREE WAYS

Everything below is drawn against the same dollar axis, so a bar's length is the cost and a block's width is what that part actually costs. The first two rows are the same machine at two points on its cost curve; the third cuts the same money by where it sits on the body instead of by what it is.

$0$20K$40K$60K
28actuators in a unit
20coreless motors in the hands
14roller screws in the load-bearing joints
2.8×the cost without the Chinese base: $131K against $46K
01 · ROBOTICS SUPPLY CHAIN MAP

Who actually makes the parts inside a humanoid robot.

Where the — makers sit, by country and — where the data goes that far — by province. Click a bubble, or filter below: a subsystem and a country to see who makes that half of the robot there, a part and a buyer to see who supplies it to that programme. Export gives you exactly what is on screen.

02 · GLOBAL ROBOTICS COMPANIES

The global robotics companies, and where they sit.

The other end of the same table: a supply base is only worth what the demand behind it is worth. Every maker with a humanoid on file, turned on the globe — most of them one platform and a plan, a few already placing volume orders against the index above. Drag to turn it, click a country to filter.

03 · WHY BUILD HERE

A decade of capability, an hour apart, at half the price.

CARRIED OVER FROM CARS

The same firms, one industry earlier

Tuopu, Sanhua and Shuanghuan were inside Tesla's automotive supply chain first. A decade of precision manufacturing and cost control in electric vehicles carries across to joints.

ONE-HOUR CIRCLE

A cluster, not a list of vendors

Zhejiang, Jiangsu and Shanghai hold a base dense enough to move a sample in twenty-four hours. That density is what a new site cannot stand up quickly.

PRICE, PART BY PART

Where a $20K robot becomes arithmetic

Harmonic reducers at 40–60% of the Japanese price, roller screws at about half the Swiss one. Without this base, one estimate puts the same robot at 2.8 times the cost.
