Algorithm Tuning
The final step was to get the algorithm tuning on-point. The first implementation was inconsistent. On some runs, the angle calculation seemed to be very accurate when run on the test rig. However, on subsequent runs, it seemed to be either offset (e.g. reads 90 degrees instead of 0 degrees) or inverted (e.g. angle decreases…
System Integration 3/3
After our hardware wizards worked their magic in reworking the boards, we ran through our tests again. First off was the GPIO toggling test. Finally some hope! Both SDL and SDA lines seemed to be toggling properly. Next, we tried getting raw IMU data from each of the BNO055s. And what do you know, suddenly…
A brief detour into fashion design
It’s easy to forget that FACTS is a wearable device, since most of our posts have been largely concerned with bring-up. However, we are proud to unveil our knee sleeve! It consists of two zippered pockets, each containing the enclosed PCB, as well as small holes to allow the motor wires (not pictured) to leave…
