Volvo Ibex

Another contest, another build. LEGO Ideas posted a contest to build your idea of the Volvo construction vehicle of the future using LEGO Technic bricks. This was my entry for the contest, which did not win, but was a design I was happy to complete.

The design was inspired by the Volvo Sfinx and the Hyundai HFex Concept as I was interested in trying the various tracks, and a foldable boom. I started with the track sections, with four idetntical modules. Each are connected to the center turntable with a worm gear assembly for individual track movement. The system is enough to hold the full MOC, but not overly strong.

Next came the superstructure. I created a conventional cab on the left, and added some fuel cells on the back. These cells can slide out the back of the superstructure to be easily replaced. Next came the boom. I wanted a three section boom that would fold, and extend in a variety of directions. Each of the three pivots is operated by a worm gear mechanism. The best manage the length of the boom, the main boom used a worm and 48z gear, the second used a worm and 24z gear, and the final boom used a worm and 8z gear. I added a ball join at the end of the boom to allow for multiple attachments.

The entry did not win the contest, but I was happy with the result. It was creative, and functioned well. I like the way it looked, and was happy with the track setup.

Happy building.
