SyncMotors

[sven]

Hello, everyone!
First of all: I am sorry for possible linguistic mistakes because i am from Germany.
My question is:
How can i control 2 Motors at the same time?
I have already heard of the class SyncMotors that is provided by icommand 0.5 , but i don´t want to use this outdated library.
Is there any other way?

Hi,

In the current release of Lejos each motor is synched against time. Time is the same for all. As a consequence all three motors are synched to each other. Only regulated motors are synched. There is no need to activate it.

Ok... but which classes or methods do i have to use to start or stop 2 Motors at exactly the same time?

[Aswin]

You'll have to apply the forward method and the stop method to each of the motors. If you make sure that you apply them right after each other then this so little time between them that this will not have any effect.

I´ve already tried this, but because of the little Time difference between the two Motors, the Robot turns ca. 10 degrees.

Set the immediateReturn param to true on the first stop().

Are you using Bluetooth to remote-control the NXT?

10 degrees is a lot. You should check the mechanics.
You could lower the maximum acceleration of the motors. There is a method to do so.
