We have had the Vex IQ for a few days and having a blast with it but we have ran into a few errors.
I was wondering if my Vex IQ brain is bad, if someone else can try this and let me know if they have same issues that would be great. Thanks
- Program: RobotC 4 30 day free trail with Vex IQ update to 1.7
- Sample Program used: Gryro Display Values.c
- Problem on the Vex IQ the values will move a degree every second when the robot is sitting still
- I have 2 gryro sensor and this has happed to both.
I updated every thing and made sure gyro was on a firm foundation and gave it a 60 second delay at the beginning and it still changes the degree and heading values by 1 every second.
I spoke with one of the ROBOTC developers about the calibration functionality in the gyro. I believe that it may be part of the next release. You can chose a number of different levels of calibration. The longest one takes 60 seconds and will result in a drift rate of 0.035 dpm. However, very reasonable results can be achieved with just a 4 second calibration cycle, which results in a 0.56.dpm drift rate.
When the gyro API was first created, this functionality had not been published or exposed and so was not implemented.
I had this problem and may have been caused by a low battery as previously it was fine. Still trying to identify problem.
Any solutions to this issue? We have just purchased a brand new vex iq kit and a gyro sensor, we are using RobotC and the sensor just keeps decrementing. I see in RobotC there are some parameters for calibrating the gyro e.g. “gyroCalibrateSamples1024” but there is no documentation I can find or sample code I can find that can help me calibrate it. I tried lowering the sensitivity… all that does is slow down the rate at which the sensor decrements.
