VARIABLE LINK FOR WALKING ROBOT AND VARIABLE LEG ADOPTING THE SAME

摘要

PURPOSE: A length-variable link of a walking robot and a length-variable leg of a walking robot equipped with the same are provided to improve walking efficiency, since the leg length of the walking robot can be adjusted in real time. CONSTITUTION: A length-variable link(10) of a walking robot comprises a length varying unit. The length varying unit is formed of first and second connectors(20,30). One end of the first connector is opened. The first connector is hollow. The first connector comprises a motor(22) and a rotating rod(24). The rotating rod connects to the motor. One end of the second connector is inserted into the first connector. The second connector comprises a nut portion(32) and a receiving part(34). Threads are formed on the inner circumference of the nut portion so that the nut portion can be thread-combined with the rotating rod. The receiving part accepts the rotating rod.
