Abstract:
1. A horizontal articulated robot comprising: a base; a first arm connected to the base; a first motor that rotates the first arm; a first velocity measurement section that measures a first rotational velocity of the first motor; a second arm connected to the first arm; a second motor that rotates the second arm; a second velocity measurement section that measures a second rotational velocity of the second motor; an angular velocity calculation section that calculates a first angular velocity of the first arm from the first rotational velocity, and calculates a second angular velocity of the second arm from the second rotational velocity; a single angular velocity sensor obtaining a detection value corresponding to at least the first angular velocity and the second angular velocity; and a control section that calculates a subtractive value by subtracting the first angular velocity and the second angular velocity from the detection value of the angular velocity sensor, and controls the first motor based on the first rotational velocity and the subtractive value, wherein the single angular velocity sensor is provided for the first and second arms collectively.
