-UART and USB interface
-LSM6DSL for gravity compensation
-8 strain gauges
-easy to make (CNC machine required)
I am currently designing a 3-axis force sensor with gravity compensation as a part of postgraduate course. The idea is, that the unloaded sensor will show no force applied in all three directions for which I will use LSM6DSL to measure orientation.
All files (hardware, PCB, software) will eventually be available when I decide that the project has come to a stage where it will be usable (repeatable results in desired tolerances) and easy to make by (almost) anyone.
