Title:
ROBOT MECHANISM AND PARALLEL LINK ROBOT
Document Type and Number:
WIPO Patent Application WO/2023/002641
Kind Code:
A1
Abstract:
A robot mechanism 1 using a parallel link, and comprising: a first output base 250; a first parallel link mechanism 13 disposed on one side of the first output base 250; and a second parallel link mechanism 15 and an end effector 500 on the other side of the first output base 250. The first parallel link mechanism 13 comprises a first drive unit 101 for generating a linear output, and a second drive unit 102 for generating a linear output. A tilting link mechanism 400 including a mass body 430 is connected to the first drive unit 101, and the second drive unit 102, the mass body 430 creating a second moment load in a direction of reducing a first moment load which is exerted on the first parallel link mechanism 13 by the weight of the second parallel link mechanism 15 and the end effector 500.
