the postion of the iRobot Create in its environnement.
In the odometry variable are stored :
val in mm) that the Create has
traveled since URBI server was launched
angle rotated since server launch
radius, angle
and velocity
You can use the odometry.move(velocity, radius) function to
control your robot. It is a direct access on command 137 in iRobot protocol.
odometry.move(40, -200);
This example will make your robot move at a global velocity of 40 mm/s and turn on the right following the arc of a circle of a radius of 200;
