Mechanical design

First, we will be taking a look at each of the mechanisms that allow the Security Tank to do its job.

Drivetrain

The drivetrain is the mechanical system that allows a robot to move. The drivetrain on the Security Tank is actually quite simple. It uses caterpillar tracks, also known as tank treads.

Tank treads consist of a belt or a chain that runs across at least two wheels or pulleys. They work in pairs, with one on each side of the vehicle. The treads essentially make two large, continuous surfaces that the robot drives on. This provides a large contact area with the ground and allows a tank to have maximum traction over all surfaces. Changing the power split between the left and right tracks allows the...
