  • Arm structure and transferring apparatus
    Patent number: 10926405
    Abstract: According to one embodiment, an arm structure includes a base, a first link, a second link, a connecting member, and a gravity compensation mechanism. The first and the second links are rotatable in a vertical direction. One end side of the first link is pivotally attached to the base via a first rotating shaft. One end side of the second link is pivotally attached to another end side of the first link via a second rotating shaft. A length of the first link is same as a length of the second link. The second link rotates around the second rotating shaft. A rotation angle of the second link is twice a rotation angle of the first link. A rotation direction of the second link is opposite to a rotation direction of the first link. The gravity compensation mechanism compensates for torque generated around the first rotating shaft by gravity.
