Both vision and force control are used to program a robot so that a tool having a tip can follow a desired path visibly marked on a workpiece when the tool is to perform work on the workpiece. There is a force sensor, a camera positioned to view the visibly marked path and a computing device. When the tool tip is in controlled contact with an area of the workpiece that includes the desired path, the camera and the force sensor each provide information to the computing device. The information is used to develop a program to move the robot to cause the tool tip to follow the desired path when the tool is to perform work on the workpiece. The tool can move in relation to the workpiece and the camera is mounted on the robot or the workpiece moves in relation to the stationary camera and tool.
