Move the Robot forward for 1 rotation




Move the Robot forward and rotate the head together for 1 rotation





How to use “turn motor () on” block?

This block allows to turn on the motor continuously until you use “turn motor () off” block.





Rotate the Robot right side continuously

How to use “turn motor () off” block?

This block allows to turn off the motor.





How to use “set motor () speed () %” block?

This block allows to set the motor speed to specific %


.



How to use “set motor () direction ()” block?

This block allows to set the direction. There are 3 directions available – this way, that way and reverse


This way:

This direction allows the robot to move forward


That way:

This direction allows the robot to move backward


Reverse:

This direction allows the robot to move opposite direction of previous direction
