power

private int power

Constructor Detail

BasicMotor

public BasicMotor(Port motorPort)

Constructor

Parameters:

motorPort - port

Method Detail

setPower

public void setPower(int power)

Set power

Parameters:

power - new motors power 0-100

getPower

public int getPower()

Get power

Returns:

power

updateState

protected void updateState(java.lang.String newMode)

Update the internal state tracking the motor direction

Parameters:

newMode - mode

forward

public void forward()

Causes motors to rotate forward.

backward

public void backward()

Causes motors to rotate backwards.

isMoving

public boolean isMoving()

Returns true iff the motors is in motion.

Returns:

true iff the motors is currently in motion.

flt

public void flt()

Causes motors to float. The motors will lose all power, but this is not the same as stopping. Use this method if you don't want your robot to trip in abrupt turns.

stop

public void stop()

Causes motors to stop, pretty much instantaneously. In other words, the motors doesn't just stop; it will resist any further motion. Cancels any rotate() orders in progress
