Case

A robotics startup in South Korea developing humanoid robots for healthcare and education needed gears that could deliver lifelike, silent movements. Standard gears created noise and backlash, making the robots appear less natural and less reliable for interaction.

DDGear designed precision small-module joint gears with micron-level tolerances and polished surfaces. These gears minimized backlash, reduced noise, and supported smooth torque transfer in elbow, wrist, and actuator assemblies.

With DDGear’s solution, the robots achieved 30% better movement stability and significantly lower noise. This improvement enhanced the robots’ acceptance in sensitive environments such as eldercare facilities, helping the startup secure new clients.
