Abstract
The integration of robotics in the process of production automation not only at large, but also at small-scale, lightly convertible, enterprises, has led to an increasingly widespread expansion of collaborative robotics (CoRT). In this case, the complete safety of the industrial robot in relation to a human located in the same workspace is provided, but the exploitation operations of the industrial robot, especially its programming, are simplified to the maximum. In fact, it doesn’t require from operator any additional knowledge or skills related to robot control. In most cases, the operator can simply move the industrial manipulator (IM) grip along a predetermined path and this movement will be remembered, i.e. IM programming is carried out by demonstration. Nevertheless, this method is still associated with a certain risk, when it comes to a sufficiently large IM. In addition, this method is not applicable when performing operations that require sufficient accuracy. Difficulties appear also when performing assembly operations. The application of the augmented reality interface for programming collaborative manipulation robots is proposed in this paper. The proposed method can be named virtual IM programming by demonstration. In this case motion programming occurs without turning on the IM and with use of the 3D model of the manipulator’s grip or an object held in the grip, the working tool etc. This model’s motion is performed by the operator, the last observes through miniature screen of transparent glasses. At the same time, the operator sees the surrounding reality, which is necessary for the correct choice of movement and allows avoiding possible collisions. In difficult situations, the operator uses their own intuition, experience when programming the movement, which allows us to call this method “intuitive programming”. After the operation is completed quite satisfactorily from the operator’s point of view and according to objective indicators, that can also be measured, the IM turns on and repeats the given operation or sequence of operations when the human operator has already left the operational field. A technical solution to the problem is proposed, as well as preliminary studies on the accuracy of this CoRT programming method.
