Abstract Real-time, three-dimensional (3D) visualisation technology can be used at construction sites to improve the quality of work. A 3D view of the landscape under work can be compared to a target 3D model of the landscape to conveniently show nee

Road map for implementing AI-driven Oulu Smart excavator

Autor: Susanna Pirttikangas, Mikko Hiltunen, Hassan Mehmood, Tomi Makkonen, Matti Immonen, Rauno Heikkilä

Publikováno v: Proceedings of the 38th International Symposium on Automation and Robotics in Construction (ISARC).

Evolving machine control systems for excavators are getting more capable every year in civil engineering, now they are usually equipped with hydraulic motion control, localization, and design models in form of building information modelling (BIM). Ma

The aim of this research is to create a 4D point cloud map from a trench through a solid-state 2D profilometer. The profilometer is integrated with an 8.5-ton medium-size excavator's machine control system with pose calculation. Accordingly, the poin

Model-Based Control of SMA Actuators with a Recurrent Neural Network in the Shape Control of an Airfoil

Autor: Tomi Makkonen, Kalervo Nevala, Pekka Isto, Tomi Lindroos, Jari M. Ahola

Publikováno v: Solid State Phenomena. :278-283

This paper describes the development of a neural network control for shape memory alloy (SMA) actuators as well as the control tests. Precise control of SMA actuators that are integrated in the composite structure is difficult because of the hysteret
