| I have a CMPS03 Electronic Robot Compass installed on a Stinger robot and it doesn't get the angle right when I move my robot from 90 to 90 degrees until I reach 360.The corresponding value for 90 degrees is approx. 63 because the real value for 360 degrees is actually 255.When I get my compass out of the robot and make measurements with the compass on the table it seems ok, but when I do the same measurements with compass on the robot, angles are wrong. I try the same measurements with the compass on top of the robot because I figured that the compass will not detect earth's magnetic right if it's mounted inside robot's metallic chassis.Even so, the compass returns bad angles.Have to mention that I place the compass on the piece of material included in compass pack and i used tape to fix it on the robot.I didn't want it to make direct contact with metal and I didn't used screws.In one position compass returns 120 degrees and when I turn it to 90 real degrees it shows 123 ! The real value suppose to be 120 + approx 63 degrees corresponding to 90 degrees.Is it possible to interfere with the sensor panner ?
