Meadow’s Status Report for 3/22/2025

This week I learned more about how to interact with the BNO055 and the necessary code. I managed to calibrate the acceleration that was posing issues from last week and successfully configured the x, y, z acceleration and rotations about the x and y axis. The setup is stable and my output values are consistent every time. It seems easy to visually confirm the accuracy of the orientation angles, but I will confirm them with a protractor or something later. I’m unsure about the accuracy of the acceleration values because they seem to lag in changing (or not change at all) for a variety of short movements. However, this may just be an inability to comprehend what these values should be reporting. So far I’ve been analyzing this data straight through the Arudino IDE and using its serial plotter and monitor. These will not be sufficient to test against the ground truth (mostly because the plotter is pretty frugal),  so I was trying to find a reliable serial plotter software to run my experiments. But I couldn’t find one that works. Still looking for that fix. Unfortunately I was unable to test against ground truth for this reason and it will have to be postponed another week. But the sensor readings have made reassuring progress! Next week I want to implement the feature to save calibration status so I don’t have to redo it every time I want to test something and I want to figure out the plotting software situation to challenge the sensor accuracy. I also need to look into getting sensor velocity; I was under the impression this sensor calculated its own velocity (part of the reason we chose it), but we have yet to find documentation on this.
