Why IMU data are sampled in irregular intervals，what is the expected fps of IMU data ?
for example, in Cooking_and_Kitchen_Clean/clean_bowl/00001/00001.mcap, the interval pattern is shown below.
2917000
6643000
3377000
12690000
3948000
3384000
6668000
3273000
6646000
3346000
7118000
2872000
6987000
Hello, the current hardware stores the IMU data through an automatic streaming method, which results in uneven data intervals. We have implemented some optimizations on the software side during the trajectory recovery stage. The latest hardware has been updated to use a PPS hardware trigger method, ensuring absolutely stable frame rates and time intervals. This portion of the data is currently being collected.
