Automatic Robot-Guided Form Scan and Coating

September 20th, 2022 | by

 

In this project, the forms are detected and their edges are realized by a laser scanner mounted on the end effector of the robot. The collected data are synchronized and filtered, and a suitable trajectory is created for coating the inner surface of the forms. Several variables, such as the speed of the nozzle, distances and gaps, the size of the nozzle and the outlier for a homogeneous coating can be selected during the trajectory planning.

Motivation

The project was initiated with the motivation to increase flexibility in scanning and coating various molds.

Method

In the context of this project, synchronization is required between three systems

The sensor software, which is responsible for the acquisition of the data (synchronized with movement of the robot).

The program, which is responsible for post-processing the data and calculating the trajectories for the robot.

The Robot control system, which receives the information of the trajectory and executes it immediately.

IGMR Consensus In Sensor Robot Network

August 24th, 2022 | by

Agile and freely networked assembly systems are characterised by the sensoric-supported cooperation of several mobile and stationary robots. However, the dynamic transformation of the production lines demands especial control strategies for robotic manipulators. Fast and reliable motion planning and control schemes should be developed that appropriately react to the changes in the environment and setpoints, and produce feasible motions. These assembly systems can then be mapped into the structure of a meta-model that leads to the creation of digital shadows of the factories of the future.

A multi-layered task sequencing approach

August 22nd, 2022 | by

Cobots are highly sought by manufacturing companies in contrast to fully automated production lines, as they provide the additional benefit of flexible operations. A major hurdle with current collaborative setups is tedious setup times for efficient and robust co-working as well as poor support for random interruptions.

This project focuses on enabling autonomous collaborative operations for serial manipulators where interruptions from human agents occur at random while ensuring minimal setup times. To this end, two primary aspects that impact task execution are addressed, namely execution time and co-working as enumerated below:

  1. A method is developed to minimise the total distance travelled, by following the most optimal sequence for the given task while retaining online operational capabilities
  2. A real-time replanning and co-working algorithm for randomly interruptive environments is developed and implemented to ensure continued operation even when regions of the workspace are occluded while guaranteeing safety of the human agents in the workspace. The co-working controller operates fully autonomously.

An example of the working of the deployed on a prototype platform consisting of a collaborative UR10e arm, a stereo camera for static environment mapping and a laser scanner for mapping of dynamic obstacles is shown in the video.

IGOR Tper: The Robot with non-spherical wrist

August 3rd, 2022 | by

The next generation of our robot is designed. The new robot is called IGOR Tper. This robot has a non-spherical wrist, that makes the motion planning for the robot rather challenging.

The IGMR visits the Automatica in Munich

July 27th, 2022 | by

After a long, involuntary break, IGMR was able to visit Automatica in Munich for the first time again. Together Jan Wiartalla, Amir Shahidi and Sophie Charlotte Keunecke explored various innovations and presentations and had many interesting conversations. In addition, some final year students of RWTH and IGMR presented their extremely interesting projects at Automatica and offered an exclusive view even beyond the exhibited possibilities.

On the last day of the fair, June 24. 2022, Sophie Charlotte Keunecke represented IGMR at a panel discussion on “Automation and robotics: what drives the new generation?” at the Automatica Forum. You can find the video here on the Youtube channel of Automatica.

Haptic Feedback System RePlaLink

July 22nd, 2022 | by

The videos are also available on our Youtube channel:

Humans interact with hand-actuated products on a daily basis. Examples are car doors, manual presses, furniture doors, machine housings, fitness equipment, or reconfigurable types of furniture. The RePlaLink can be used for the simulation and haptic representation of such mechanisms based on virtual prototypes. This makes it possible to improve the development process of such systems and reduce the use of physical prototypes.
The RePlaLink consists of a servo-driven kinematic structure with a handle as haptic interface. Due to its structure, it is particularly well suited to simulate planar mechanisms. The system measures, among others, the user forces, takes them into account in a real-time simulation of the virtual mechanism and displays its reaction. This allows users to directly feel the mechanism’s haptic properties while operating the system. Users can change them interactively by modifying the mechanism’s parameters and get direct haptic feedback. This enables fast, inexpensive, and frequent validation and evaluation of haptic properties, even at early development stages. The videos introduce the structure of the RePlaLink and show the haptic simulation and synthesis of an exemplary hand-actuated mechanism.
