A mobile high-tech observation trolley was completed in Eckartsau Castle Park at the end of 2021. The bionic support structure made of Kerto / LVL was manufactured by Leidorf Holztechnik. 
 

Robot joinery ideal for the project

The observation trailer has a support structure that looks like it has grown. Such complex and very sophisticated projects are ideal for our robot CNC system. The bionic structure was made of laminated veneer lumber. The design of the "Spähikel" was created by Maik Perfahl/mostlikely on behalf of the Austrian Federal Forests.
 

Experience nature with all senses

Experience, discover and explore nature on site with state-of-the-art technologies: With the mobile high-tech observation vehicle "Spähikel", the Austrian Federal Forests (ÖBf) are breaking new ground in nature education in the Danube Floodplain National Park.
The Spähikel offers space for up to twelve people and is at the cutting edge of science and technology. From animal voice recognition systems and wildlife cameras to drones and virtual reality goggles: The Spähikel has a network that sends high-resolution virtual reality video and audio files to the observation van.

With the so-called BESO method, the kerto-structure of the observation trailer was statically optimised. This made it possible to reduce the weight of the spähikel. This video explains the BESO method for material optimisation of static structures.

Bidirectional Evolutionary Structural Optimisation (BESO) is a structural optimisation method used in engineering. BESO is an iterative process based on the application of topology optimisation that aims to design structures with optimal stiffness and minimum mass.

BESO uses evolutionary algorithms to optimise the structure based on criteria such as strength, stiffness, vibration characteristics and material distribution. The algorithm successively removes the structural elements with the least impact on the overall stiffness and adds new elements to create an optimal structure. The load conditions and boundary conditions are taken into account to ensure a realistic structure.
