The Move Tank block can make a robot drive forward, backward, turn, or stop. Use the Move Tank block for robot vehicles that have two Large Motors, with one motor driving the left side of the vehicle and the other the right side. You can make the two motors go at different speeds or in different directions to make your robot turn.

　

＊Robot vehicles with two drive motors can also be controlled by the Move Steering block. The Move Steering block is similar to the Move Tank block, but has a different way of controlling turns.

　

Select the two motors (A, B, C, or D) that you want the Move Tank block to control by using the Port Selector on the top of the block. Click on each motor letter to choose the port for that motor. The first port should be the motor on the left side of the vehicle, and the second port should be the motor on the right side.

　

Use the Mode Selector to select how you want to control the motors. After selecting the mode, you can choose values for the inputs. The inputs available will change depending on the mode. The modes and inputs are described below.

　

[Modes] : On , Off , On for Seconds , On for Degrees , On for Rotations
