[ros-users] [Discourse.ros.org] [TurtleBot] [TB3] Defectuous IMU?

[Matt Mgn]

Hello, 

I am working on turtlebot Buger and Waffle, but I get curious values from IMU.
Linear acceleration on z axis in not equal to ~9.8 m/s. And when the robot is static, I have non zeros values on x and y axis.
I have those strange values on both Burger and Waffle robots. Curiously IMU on Waffle was working fine last week. 

Some idea ?

Matt
