| Advantages of Hydraulic Robot |
Hydraulic robot is useful for Dynamic, High power, High torque systems.

A system capable of flexible processing of diversified designs, high payload & extensive operation domains without any restrictions
Whereas hydraulic actuators & components have no restrictions and allow extensive design & flexible processing of payloads & operation spaces, motor-driven systems have limitations in payload ratio based on the size, with the payload being proportional to size in general.
Since KNR¡¯s hydraulic actuator has an excellent power in reference to weight of more than 10 times compared with standard motors coupled with harmonic gear, it is suitable for robots handling heavy weights.
An optimum system applicable to hazardous environments.
Hydraulic system is suitable for dangerous environments such as underwater, high temperature, etc. that are normally inaccessible by humans.
A system allowing application of a small controller irrespective of actuator¡¯s capacity.
Hydraulic System allows high-precision control, with a remarkably small control system compared with Electrically driven motors, and allows application of small products irrespective of capacity. Power supply & signal line also allow small & simple configuration irrespective of actuator¡¯s capacity, making it particularly advantageous for application of Multi Axis or Articulated Robots such as Manipulator or Walking Robots.
A system suitable for high-speed & high-frequency response performance.
Robot driving element with application of KNR¡¯s hydraulic servo valve has a speed & frequency response performance of a few 10Hz to a maximum of 100Hz, which is a range sufficient for application to robots.
