Lego Wiggler Vehicle

This vehicle uses a back and forth wiggling motion in order to move forward, remotely similar to the way lizards move. Each of the four wheels will only turn in the forward direction, prevented from reversing by axle-end connectors. A Lego 9 Volt Micromotor is utilized in order to achieve the wiggling motion between the front and back halves, with a reinforced double hinge to allow only one plane of motion between the two halves.

If there is any extraneous motion, the movement of the entire vehicle will suffer, so the hinge joint in the center was reinforced and is smooth, while only allowing the side-to-side twisting. The geometry is similar to the pneumatic log loader, Technic set #8443 though my vehicle has only 4 wheels.

Here are some images: (with explanations)
