First a line. Then a robot.

Hangyeol Robotics has designed and built industrial robots in Daegu, Korea, since 2009. We draw every part ourselves, down to the inside of each joint.

• Payload 10 kg (22 lb)
• Reach 1,300 mm (51.2 in)
• Repeatability ±0.03 mm
• Weight 33 kg (73 lb)
• Protection IP66

The drawing becomes real.

Design, assembly, and shipping all happen under one roof at our Dalseong plant. The 4,800 robots we have delivered so far are at work in 23 countries.

Hangyeol means the 10,000th time matches the first.

Our name comes from the Korean word hangyeol-gatda: steady, unchanging. Since we started building welding cells in a small shop in Daegu in 2009, one standard has guided us. Tens of thousands of moves later, the robot should still land on the spot it hit the first time.

HG-C10-13 collaborative robot

Repeatability ±0.03 mm

How far the tool tip may stray when it returns to the same point. Every robot is measured to ISO 9283 before it ships.

Payload 10 kg (22 lb)

The weight the wrist can carry, counting the gripper and tool.

Reach 1,300 mm (51.2 in)

How far the wrist reaches with the arm fully extended. Enough to cover a full workbench.

Model HG-C10-13

The name is the spec: collaborative (C), 10 kg payload, 1,300 mm reach. Axes 6, Safety 18 functions · ISO 13849-1 PL d / Cat. 3, Protection IP66, Weight 33 kg (73 lb).

Every joint is built the same way.

We fit each one with a motor, a reducer, a torque sensor, a brake and an encoder. Each joint measures its own load and stops itself if anything is off.

18 safety functions · ISO 13849-1 PL d / Cat. 3

Open up one joint.

3-1 Encoder and driver board

A dual encoder reads the angle on both the motor side and the output side, on the same board as the motor driver. The two readings are checked against each other, and the joint stops if they disagree.

3-2 Electromagnetic brake

When power is cut, springs press the plates together and hold the joint where it is. The arm does not sag in a power outage.

3-3 Frameless motor

A stator wound with copper and a permanent-magnet rotor. With no housing of its own, it sits right inside the joint and keeps the joint short and light.

3-4 Strain wave gear

An elliptical cam flexes a thin toothed cup into the teeth of the outer ring. The teeth mesh with no play, which holds repeatability to ±0.03 mm.

3-5 Joint torque sensor

Strain gauges on the spokes measure the load on the joint. Since our second-generation cobots in 2026, all six joints have one.

3-6 Cross roller bearing

Crossed rollers carry loads from several directions at once. The upper arm bolts to the outer flange.

3-7 Hollow shaft and cables

Cables run through the hollow shaft, so they never twist as the joint turns. With no exposed cables, the body is sealed to IP66.

Back to the same spot.

After tens of thousands of moves, it lands within ±0.03 mm of the same point. The thin lines trace every path the tool has taken. The paths vary a little. The point does not.

A robot for collaborative applications. A risk assessment is required before installation.
