The exhibit is a toy-sized tractor with a display on its trailer. Among rapidly passing plants, the player must recognize and tap the weeds on the display to destroy them in the game with the laser. The operation is simple, and the interactive game is thus suitable for all ages.

The idea: More environmental protection through laser technology
The background of the entertaining game is an important concern. Scientists at the LZH are working on an environmentally friendly method of controlling weeds in plant production. In the WeLASER project, among others, they are working in an international team to research how the growth center of weeds can be obliterated and thus lethally damaged through a precise laser beam. The project partners are developing an image processing system that uses artificial intelligence to distinguish crops from weeds. The goal is to be able to control weeds sustainably and without chemical products in the future. The chemical burden on food would decrease, surrounding, non-disturbing plants could increase biodiversity, and insects would also be spared.

German pavilion presents interactive exhibits
The World Expo 2020, postponed by one year due to the pandemic, will take place in Dubai from 01 October 2021 to 31 March 2022. In the German pavilion, interactive exhibits in the thematic areas of energy, the city of the future, and biodiversity will convey what sustainable innovations in these areas might look like. The "Food Farming Laser" is one of 36 exhibits that the German pavilion is displaying on behalf of the German Federal Ministry for Economic Affairs and Energy.
