90 degree turn

[rhitam01]

So i am buidling a rover and i have an intel realsense imu dept camera, which is mounted infront of it, now i want to change the direction of the rover turning left or right which is 90 degree turn, how do i calcukate the perticular turn?

Hi @rhitam01 Horizontal left-right turn of the IMU is called yaw. The gyro yaw is represented in the RealSense coordinate system by 'y'.

#4391 (comment) has a Python script for retrieving gyro x, y and z values.

The RealSense SDK's rs-motion example provides C++ code for accessing the gyro value.

It sounds from your question that you would like to know how to make the rover turn left or right though. The IMU will be turned by the rover (rather than the rover being turned by the IMU), since the IMU is mounted to the rover and so will be moved in whatever direction the rover turns in. So the rover turn must come first before the IMU values are changed by the turn - the IMU cannot make the rover turn.

Hi @rhitam01 Do you require further assistance with this case, please? Thanks!
