Precision for Humanoid Robots

In a world where humans and machines are more integrated than ever, the JUNKER Group delivers the technologies that drive progress by offering high-precision grinding solutions for the key components of humanoid robots.

Transmission elements in humanoid robotics are mechanical components that transfer movements and forces from a drive to a joint or other movable parts. They are crucial for the efficiency, precision, and dynamics of movements. For the high-precision machining of these key components—such as joints and drives—the JUNKER Group offers specialized grinding solutions.

In complex robotic systems, linear and rotary drives are combined, such as rotary drives in hips and shoulders, and linear drives in fingers, arms, and legs. This combination enables high mobility and functionality.

Linear Drives

Straight-line movements are often used in gripping mechanisms, where higher force transmission occurs. Typical designs include ball screw drives and planetary roller drives.

Rotary Drives

Rotational movements are essential for joints, such as in robotic arms. Typical designs include cycloidal, harmonic drive, and planetary gear systems.

The production of these components requires grinding processes that ensure the necessary dimensional accuracy and surface quality to meet precision requirements and minimize noise emissions. Our machines guarantee excellent surface quality, process reliability, and flexibility with high output—ideal for the demands of modern robotics.
