… of Linköping. The purpose of this project was to investigate the ability of an industrial robot to drill holes in aeroplane structures using orbital drilling. How the project tests were carried out and the results of these tests are presented in the first part of this thesis …
… and produce according to customer demand. In order to reduce the cost of wages industrial companies are now considering moving the manufacturing to low-cost countries. To keep up with the competition in the market without moving the manu- facturing abroad, Lean Automation was …
… regulators that can increase the possibilities of rejecting disturbances on an industrial robot. The robot model used has three degrees of freedom, corresponding to the three main links on ABB:s IRB7600. The simulation environment is created using Matlab, Simulink, and Robotics …
IRB 340, Flexpicker is an industrial robot used for sorting, packaging and the handling of details up to two kg. The Flexpicker is a delta robot, meaning that it with three arms controls a triangular plate, swivel, in a work area shaped like a cylinder. Joints using plain …
… a method for experimental identification of the inertial parameters of an industrial robot, using measured torques and joint angles. A dynamic model of the first three joints of the robot has been identified. To achieve good identification results, it is important to carefully …
Design, simulering och experimentell verifiering
This thesis approaches the problem of estimating the arm angles of an industrial robot with flexibilities in joints and links. Due to cost-cutting efforts in the industrial robots industry, weaker components and more cost-effective structures have been introduced which in turn …
… thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of the robot, after …
… master thesis studies how much the cycle time, i.e. the time it takes for an industrial robot to perform a given task, can be reduced if an extra degree of freedom (DOF) is added to the robot system. The extra DOF consists of a linear track, which is supposed to be used in an …
… project in collaboration between Linköping University, Lund University, and industrial partners such as Combi Wear Parts and Smålands Stålgjuteri AB. The casting process creates random incurred burrs and defects, which must be removed during a cleaning process to make sure that …
… year. According to this thesis work the result is a 4x9 meter cell with two industrial robots of the type ABB IRB6650S. The cycle time to magnetize one translator was calculated to about 10 hours. This prototype of project can possibly be implemented in a full-scale production …

… the organization and its ability to create meaning-changing innovations. The industrial robotics is a market in need of, perhaps, if not other markets but of finding new ground that results in the change of meaning. What happens when you stand at the intersection of main areas …
… The demands for efficiency and reliability have been set very high in the industrial sector. Optimizing of the material handling will give the company higher cost-effectiveness. Around the robot there are different kinds of material flows, to optimize the cycle time, consisting …
… parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of …
This thesis studies path generation for industrial robots of six degrees of freedom. A path is defined by connection of simple geometrical objects like arcs and straight lines. About each point at which the objects connect, a region, henceforth called a zone, is defined in which …
In modern industrial robots the components in the transmission contain nonlinearities. These nonlinearities need to be to estimated either for better control or to use the parameters for diagnosis of the system. There is a lot of work done within system identification and mainly …
