  We are pleased to present our new research project: HIRAC - Hardware Independent Robotic Assistance Controller. Cadida Software, in collaboration with the University of Applied Sciences Offenburg, has initiated this exciting project to sustainably improve the quality of life of persons with total body paralysis and persons with Locked-In Syndrome.
  
  

  Totally paralyzed individuals and patients with locked-in syndrome face significant challenges in everyday life. Even basic actions such as reaching for a glass of water are often out of their reach. The limited ability to speak also makes it difficult to use voice-controlled devices. The HIRAC project aims to help these people while relieving the burden on caregivers.

  The vision is to develop an assistance system consisting of artificial intelligence (AI), eye tracking control of the wheelchair, a gripper arm on the wheelchair and voice output. This system is intended to enable persons with total body paralysis to perform everyday tasks independently and significantly improve their quality of life.

  The development of such an assistance system requires complex technical solutions. In particular, it is crucial to develop a component that is compatible with and can control commercially available wheelchairs, robotic arms, gripping mechanisms and eye tracking glasses. This component is called HIRAC (Hardware Independent Robotic Assistance Controller).

  Our task is to develop this hardware-independent middleware that can solve the robot grasping tasks. This middleware integrates a powerful AI that merges and controls eye tracking control, image processing, sensor feedback and object manipulation. In doing so, HIRAC is designed to have a wide range of applications not only in the social sector, but also in industry. HIRAC relies on current machine learning methods, in particular Deep Learning and Reinforcement Learning.

  In addition, Cadida develops the software framework that integrates the various components such as user interface, robot control, AI, etc. We rely on valued solution in the robotics domain such as ROS2.

  We are proud to be able to work on this groundbreaking project with the support of the Central Innovation Program for SMEs (ZIM). This funding will allow us to move full steam ahead with the development and implementation of HIRAC.

  We are confident that HIRAC will make a significant contribution to improving the quality of life of persons with total body paralysis and persons with Locked-In Syndrome. We look forward to the challenges and opportunities this project will bring and will keep you informed of our progress.

  An international measurement equipment corporation needed our expertise to interface their thermal imaging cameras with LabVIEW. They were looking for a quality solution that would allow them to connect their equipment to the graphical programming system and achieve licensing by National Instruments, the manufacturer of LabVIEW.

  The project started with consulting on LabVIEW, device drivers, interfaces, and licensing. We performed the software architecture design, programming, extensive unit and system testing, and regularly demonstrated progress.

  The LabVIEW device driver for the infrared thermography cameras is now responsible for parameter exchange as well as real-time streaming and control of the cameras. The LabVIEW end user can now see the many options for device control on the user interface, as well as the analysis of the measurement data. We have been able to realize this through several examples, some straightforward and others more extensive. Extensive documentation makes the LabVIEW user's introduction to the product and device palatable and easy.

  The extensive system tests included several thermal imaging cameras for different versions of LabVIEW and resulted in over a thousand test cases for close examination, where the quality of the manufacturer's core device drivers could also be improved. Unit tests of the interface programmed in C++ were created and tested for each function and parameter, and were able to log both limit and timeout violations.

• read more

  As a B2B software service provider, we used our experience in CAD to modernize a software that had grown over 12 years. Our client, itself a large software company, developed this addon for AutoCAD and Civil for structural and civil engineering.

  Several hundred thousand lines of code were ported and modernized from C++ (COM, MFC, and ObjectARX) to C# (WinForm, AutoCAD's API). This was preceded by a feasibility study and financial calculation for this large project. In the financial calculation, we showed how the development effort with C++ for AutoCAD addons will behave over the next few years due to high migration efforts and in what timeframe the porting to a modern programming language will pay for itself.

  The porting concerned the user interface with main and context menu, ribbon, property window, commands and dialogs. The CAD part contained CAD elements (entities), reactors, Xdata, and much more. On the way it was already noticeable that the program code became shorter and simpler.

  After the porting, a three-day training period was conducted to prepare the employees for the change to AutoCAD .NET API with C#. Previously, they had already been trained by us for AutoCAD's ObjectARX and C++.

  For an international sensor manufacturer, we developed mathematical models and software algorithms for the evaluation of 3D scan data. For the evaluation, numerous filters were applied upstream to improve the calculations and optimize the output data.

  The task was to recognize and classify objects from the 3D scan data (point cloud), i.e. the recognition of the geometric shape (cylinder, cuboid, sphere, etc.). A subsequent calculation of the volume brought the desired results with fast performance.

  In the test phase, we installed the scanners at various positions in the laboratory, connected them to the embedded system and configured them. Data from a production plant was also used, to which the newly developed 3D scanners were pre-assembled. In order to produce an abundance of variants for the tests, we modeled a setup in 3D for a scan data simulation.

• read more

  For an international sensor manufacturer, we developed mathematical models and software algorithms for automatic calibration of 3D scanners. The goal of the project was to find a simple way to calibrate the scanners worldwide without using reference objects or measurement tools.

  The existing calculations were transferred to Matlab and the setup of the industrial scanner was also recreated and simulated in Matlab. In the process, the scanners could be freely rotated in space to simulate any orientation. For the calculations, the formulas were first optimized in Matlab and then implemented with Java. The user interface was expanded, the operating steps minimized and the ergonomics improved. Our developments are now used worldwide.

  For the tests, the scanners were installed at various positions in the laboratory, connected to the embedded system and configured. In a simulation that mimicked the production setup, scan data was generated and, after calibration, the calculated positions of the laser scanner were validated.
