Service Examples
AI/ML/NN tools for rapid development of vision based robotic systems
Goal: Automation of industrial processes involving large number of objects with unpredictable positions/locations.

Description: A lot of industrial processes involve operation with large number of different objects. It is hard to automate these kinds of processes because sometimes it is impossible to predetermine the positions for these objects (For example when objects are distributed chaotically in some container). To overcome this issue, we integrate 3D and 2D computer vision solutions with robotic systems for object detection, localisation and classification. In experiments we are using Microsoft Kinect V2 depth sensor for 2D and 3D information acquisition. For object detection and classification, we are developing algorithms based on artificial neural networks. One of the challenges for artificial neural network-based methods is the need for large amount of labelled data. We are exploring methods how to generate this kind of data procedurally, to allow generation of such data for various objects a lot faster with reduced amount of manual work allowing faster adaption of this method for different scenarios.Contribution to increased agility in production: Provided algorithms and methods, which are based on artificial neural networks, will allow to generate labelled data for various objects a lot faster with reduced amount of manual work allowing faster adaption of system which is capable of randomly dropped object detection, recognition, classification and pick-up by a robotic arm for different scenarios.

Super-stable impulse generator producing extremely low jitter
Impulse generator with extremely high stability and wide frequency range. It is implemented in two modifications: supporting NIM signal output and supporting LVTTL signal output (therefore it is possible to use them together with Event timers). Generator period stability in range up to 25000 ns is smaller than 1 ps (RMS). For wider ranges the reference signal is needed. Generator applications include measurement system testing (e.g. Event timers), calibration etc.

Universal Event timer producing extremely high measurement resolution
Together with Eventech Ltd the Event timer is developed capable to measure single pulse within 3 ps resolution (RMS) and maximum measuring rate up to 20 MHz. The various modifications of the timer are available (with increased measuring rate but lowered resolution). Event timers are used in SLR (Sattelite Laser Ranging) systems and have potential in LIDAR, 3-D scan, Laser Link communication systems.
