7.2 Power steering drive:

Both the wheels rotate forward during forward motion. While turning right, the right wheel rotates backward, while the left wheel moves forward. While turning left, the left wheel rotates backward and right wheel moves forward.

Power steering drive is faster and more effective than differential drive.

Below is a representation of Power steering drive:

For the deployment on the prototype the power steering drive has been used. With the Power steering drive, turns can be taken much faster.
