 [Playerstage-users] help on reading position needed From: JBR - 2007-06-30 12:35:39 ```Hi I am reading position of a virtual robot in player using Position2dProxy pp(&robot, gIndex); ... etc ... robot_x = pp.GetXPos(); robot_y = pp.GetYPos(); the robot is moving, following walls but the readings make no sense even when the robot moves horizontally BOTH X an Y change (a LOT, I do not mean changing slightly because of movement oscillation, but really changing as if X and Y were changing fast while the robots follows an horizontall, or vertical wall) can anyone help me on this? This is an example of what I am saying: x,y = -7.06034 , -3.51814 x,y = -7.02499 , -3.55349 x,y = -7.02499 , -3.55349 x,y = -7.00731 , -3.57117 x,y = -7.00731 , -3.57117 x,y = -6.98963 , -3.58885 x,y = -6.98963 , -3.58885 x,y = -6.97195 , -3.60653 x,y = -6.97195 , -3.60653 x,y = -6.9366 , -3.64188 x,y = -6.9366 , -3.64188 x,y = -6.91892 , -3.65956 x,y = -6.91892 , -3.65956 x,y = -6.90124 , -3.67724 x,y = -6.90124 , -3.67724 x,y = -6.88356 , -3.69491 x,y = -6.88356 , -3.69491 x,y = -6.84821 , -3.73027 x,y = -6.84821 , -3.73027 x,y = -6.83053 , -3.74795 x,y = -6.83053 , -3.74795 these readings were taken while the robot was following the bottom wall of the room, perfectly horizontal and with the robot making an exact 0 degree angle with that wall (paralell) (moving left to right) so, why is Y changing?! ____________________________________________________________________________________ Moody friends.
