Abstract: A vertical non-parallel link type robot having a robot arm construction with which it is possible to increase a movement range easily and cheaply without making the moving arm longer, and to make the driving motor for an upper arm lighter. The robot has a base, a revolving table mounted on the base and rotatable with respect to the base about a vertical axis thereof, a vertical lower arm mounted on the revolving table and pivotable with respect to a first horizontal axis thereof, and a mounting structure whose upper portion is pivotably supported on one side of the tip or upper end of the lower arm with respect to a second horizontal axis thereof and whose lower portion depends from and extends at a right angle to the upper portion.
