Unlike the "turtle" game, we are working with real-world components and surfaces that are not necessarily perfectly smooth. RotateAccurate(90,3000) will try to get you to exactly 90 degrees (as measured by PresentHeading()) but if it overshoots more than 3 times it will be satisfied with 8...

RotateAccurate() uses units of absolute degrees (not relative to present heading). In your second example (turtle_04), try changing RotateAccurate(90, 3000); to RotateAccurate(PresentHeading()+90, 3000); In your first example, ZeroNavigation() is resetting PresentHeading() to 0 each time so you get ...

NavigationXY() keeps track of x & y position. It has inputs GyroSensitivity and AccelSensitivity (100 and 800 are good values for most environments) which are used to determine if it is moving (global variable IsStationary). Kevin pointed out that this might be confusing so he is writing a funct...

RingoHardware updated from version 1.1 to 1.2 You can get it at https://github.com/dsoodak/Ringo Main changes are in "LookForEdge()", though there are also a few new examples for IR and one for gyroscope. The original edge detection algorithm was optimized for the hardware of the prototype...

It does have to be on to program(otherwise it is just charging). After HardwareBegin(); and PlayStartChirp();, its a good idea to put something like while(!ButtonPressed()); to prevent this issue. Maybe even follow it with while(ButtonPressed()); so it doesn't continue until you RELEASE the button. ...

A separate copy of MiscHardware (renamed RingoHardware) will be included in each example sketch (several examples should be ready for release this evening).
