Mechanical design

We will start by dissecting the physical components that make this one-kit wonder tick. 

Drivetrain

Like the Omnilander and the Security Tank, the Timmyton uses tank-style steering to drive around. However, one glaringly obvious difference should jump out at you—the Timmyton does not have tank tracks! How can it have tank-style steering without having tank tracks?

Even though there are no tank tracks, the drivetrain is still classified as tank-style because the Timmyton steers by varying the power sent to each side. In place of tank tracks, the Timmyton has wheels. One wheel is directly connected to each EV3 large drive motor. The ports for the drive motors follow the typical EV3 convention: the left drive motor is plugged into port B, and the right drive motor is in port C. The two drive wheels are tucked tightly together within the chassis so that they do not disrupt the Timmyton's shark-like appearance:
