I'm doing a thesis where I basically try to make my own stability system using the IMU and FSRs. I am reading the accelerometer values okay however when I move the robot backwards for example, the AX accelerometeter value changes as expected. However, the value stays to that amount, which doesn't make sense as an acceleration. This does not effect my ability to use the device or make a system, however I want to be clear on what I write about my project. What is this value supposed to represent? It should return back to 512 once movement has stopped but does not. If I were to read the data using the getting started information, apparently the Darwin is experiencing a constant acceleration.
Perhaps my understanding is wrong, but I have asked a couple of people and want to be clear. If anyone could help it would be a godsend.
Thank you so much in advance, Brendan.
I'm sorry about the late reply.
The accelerometer provides a direction of gravity while the gyroscope provides angular velocity.
Therefore, gyroscope value will return to its median point when stationary, while accelerometer values are unchanged.
