Control device, robot system, and robot

A control device that controls a robot including a robot arm, a dispenser provided at a distal end of the robot arm and configured to discharge a discharge object, and a plurality of distance sensors configured to detect distances to a target in a direction in which the discharge object is discharged,

• the control device comprising a control section configured to control a motion of the robot arm using values detected by the distance sensors, wherein
• the plurality of distance sensors include a first distance sensor and a second distance sensor,
• the first distance sensor is disposed between the dispenser and the second distance sensor,
• the second distance sensor is disposed along a first direction orthogonal to an axis of the dispenser and extending from the axis of the dispenser toward the first distance sensor, and
• the dispenser discharges the discharge object when a first condition that a first value detected by the first distance sensor is included in a predetermined range and a second value detected by the second distance sensor exceeds the range is satisfied.
