The invention provides a control apparatus, a robot and a robot system, and a robot controlled by the control apparatus may appropriately perform work in a target part. A control apparatus that controls a robot having a force detection part and a movable unit including an injection part that can inject an injected material to an object, includes a generation part that is configured to generate teaching data in a position of the movable unit when the movable unit is moved from the object by a first distance after sensing of contact between the movable unit and the object based on output from the force detection part.
