MTV3 (pronounced “em-t-ee-vee-three” or “em-t-E-V-3”; get it?) is a Multi-Terrain-Vehicle in a super-compact package. It may look like TRACK3R but don’t be deceived; it is not at all related to TRACK3R. MTV3 features torsion-bar suspension, terrain-conquering tracks, Remote-Controllability, loads of sensors, and much more! I was inspired by Audiultra‘s NXT TROV tank with suspension, and I thought if he could do it, so could I. So here it is: my first tank with suspension. Although MTV3 does not incorporate shock absorbers in its suspension, it uses a unique type of suspension called torsion-bar suspension.
Here is the best part about MTV3: its torsion-bar suspension! A torsion-bar suspension features torsion bars. For torsion bars I used long axles fixed to the internal structure but not elsewhere, and I attached a gear-wheel assembly at the end of the independent torsion bars. This allows the torsion bar (gear-wheel assembly) to bend under stress, which would be obstacles.
Here is MTV3 with the body shell removed. The base is very sturdy with Technic frames interlocking each other.
