We found an amazing video: how the Lego Technic Control system was used to run a real Liebherr R9800 hydraulic excavator.
The Lego company invited Paul Sariel, a polish graphic designer, to participate in a project that called for operating the Liebherr R 9800, one of the world’s biggest hydraulic excavators, remotely using Lego pieces and Control+ app.The issue of Bluetooth’s insufficient range was solved by transforming the Bluetooth signal into a wi-fi signal and then back again.
Paul job was to build the mechanism for controlling the foot pedals and then controlling the R 9800 remotely.
