Hello players... I am experiencing some trouble with the laserobstacleavoid demo. We want to show our robot hardware just wandering around not really doing something with a new patrol bot. This has a sicklms on board but it is installed upside down so we use the invert 1 option for the driver. The problem is, that the robot is driving backwards with the laserobstacleavoid program where the robot HAS NO laser. Has anyone experienced the same problem with player 2.1.1 ?! With playerv all data are correctly displayed and in command mode the robot will drive in the correct direction... Best Frederic |

I suspect that you're getting some very short, possibly zero, range readings. These may be spurious; if they're real, they may be do to a cable or something else obstructing the sensor. The laserobstacleavoid example is really simple. If it gets a short reading, just one, it will drive backward. brian. |
