making a right turn

[ayilma]

I am trying to make a simple right turn. I tried setting the speed of the two motors to different speeds but then it just goes in circles. Does anybody have any idea?

Why don't you use pilot.steer?

[jmernin]

I use pilot.rotate(90) to cause a right turn and this works for me. There are of course issues with the accuracy of the rotation which are well documented on other threads of this forum. But nevertheless, the Pilot class is your best bet for this sort of thing.

Hi Jmernin,

Interesting. The rotate( int angle) method in Pilot assumes that a positive angle will increase the angle in which robot is heading. All the Pilot and Navigator methods use polar coordinates in which angle 0 is the direction of the X axis and +90 is the Y axis. So rotate(90) should cause a rotation to the left.

My apologies, you are correct. pilot.rotate(90) does indeed cause a left turn. However, I think you can use pilot(-90) to make a right turn instead.
