How To Calibrate The Ev3 Gyro Sensor Software Solution First Lego Calibration. simply put you have a device that is making measurements. if there is a difference between a well known value and the value measured by this device then you need to calibrate the device. example you take a compass and get the direction of north measured by the compass. you compare this measurement with the real direction of north. Episode #088the ev3 gyro sensor is quite powerful, but there are some little tricks when using it. in the previous episode we showed a hardware solution to t.
Preview For How To Calibrate The Ev3 Gyro Sensor And Remove Its Drift Re: ev3 gyro sensor drift use the reset option in the gyro block (read the help file). it sets the gyro angle to zero. i've noticed this takes a short period of time, so don't trust the gyro angle reading for about 0.1 seconds after the reset. you do not want to do the rate zero (read rate read angle to calibrate the rate zero). There is a hardware and a software solution. in this video we are stopping at the hardware solution. in some of the next videos we would stop at different software solutions. more on the gyro sensor. check out the how to use ev3 gyro sensor of the lego mindstorms robotics set video tutorial. Learn what the gyro sensor does 2. learn about 2 common problems with using the gyro sensor (drift and lag) 3. learn what “drift” means 4. learn how to correct for drift with a gyro “calibration” technique 5. understand why it is important to consider multiple solutions to a problem such as gyro drift. Step one would be to remove the drift using the. hardware fix: unplug the gyro sensor, make sure the robot is still, and then plug in the sensor. software fix: gyro drift simple fix which should only need to be run once. however, i'm aware of several fll teams using this fix and even then, once in a while the robot goes crazy, because the gyro.
