Rectilineal movement speed enhancing apparatus of an orthogonal coordinate robot

摘要

A robotic mechanism includes a horizontal base, a vertical support mounted on the base, and a horizontal arm mounted on the vertical support. The vertical support is movable horizontally relative to the base. The arm includes a body which is movable horizontally relative to the vertical support and carries a member which is movable horizontally relative to the body. When the body moves horizontally relative to the vertical support, the member moves horizontally relative to the body to increase the effective rate of movement of the arm.
