Calibration system and calibration method for horizontal articulated robot

Provided is a calibration system (10) for a horizontal articulated robot (1), the system is light, and the cost of the system is low. The system (10) comprises an installation surface (30) on which abase (2) of the horizontal articulated robot (1) is installed; two reference surfaces that are provided on the base (2), that intersect with the installation surface (30), and that intersect with eachother; and a positioning jig (20) that is attached to a front end (5a) of the horizontal articulated robot (1) and that has three positioning surfaces (21,22,24), which respectively and simultaneously come into contact with the installation surface (30) and the two reference surfaces. 本发明提供一种水平多关节型机器人(1)的校准系统(10)和校准方法，能够重量轻且价格低地校准水平多关节型机器人。该水平多关节型机器人(1)的校准系统(10)具备：设置面(30)，其设置水平多关节型机器人(1)的基座(2)；两个基准面，其设置于基座(2)上并与设置面(30)相交，且彼此相交；以及定位夹具(20)，其安装于水平多关节型机器人(1)的前端(5a)，并具有分别与设置面(30)和两个基准面同时接触的三个定位面(21、22、24)。
