Lego GBC Rover is a simple bucket lift module designed by Lawrie George.
It uses an excavator bucket and a simple crank setup to lift balls from the input tray up to next GBC module.
The inspiration came from challange to build a simple module using the bucket element, from here it was a process of experimenting with different lever combinations to find one that tilted the bucket from a down to up position.
Even after I was happy with the basic mechanism it took quite a bit of experimenting to get a the loading gate and input ramp geometry just right so that balls would be picked up and transfered to the next module.
After the module had passed my workbench testing and completed a few shows I was ready to create instructions and a video of its operation (see below).
