Quadruped Legged Robot

Because the legs of field robots need enough torque to be able to support the weight of the robot and move the robot, hydraulic actuators are an excellent fit. KNR teamed up with KITECH in the development of the Korean quadruped robot ‘Jinpoong’. KNR designed the actuators and legs for the field robot, which also increased the possibility of KNR’s actuators being used in defense. KNR provided optimized designs for leg modules by combined use of linear and rotary actuators to drive the multi-leg robot. KNR is also part of a consortium with Hyundai Motors and Hyundai Rotem which manages the research and development ‘Hydraulic Wearable Robot’ project. In that project, KNR is currently developing actuators and other components for the upper- and lower-body sections of the robot, and is also developing the upper-body structure. This research can be beneficial for developing other various walking robots. Much of the research is still ongoing, and there are opportunities for a wide variety of applications.

Wearable Robot

We developed wearable robots that use hydraulic actuators for the lifting of heavy objects. KNR worked in consortium with Hyundai Motors and Hyundai Rotem on the ‘Hydraulic Muscle-Enhancing Wearable Robot’ project, in which actuators are developed for integration with the upper body of the robot. The robot will enable the wearer to lift and move objects of up to 80 kg with both arms without straining the muscles. We developed optimized rotation, torque, and bending force on an upper body structure designed to fit human movements naturally.
