In the first reference, there is a formula to find x-axis of 2 intersection spheres have same y-axis and z-axis

Depend on the above formula, we can use a points as origin and 3 points on 3 axis, then we can use origin and 1 in 3 of them to find the corresponding axis

Config TEST_MODE to True

Config data in data.txt as format

0, 0, 0 , distance

x_axis, 0, 0 , distance

0, y_axis, 0 , distance

0, 0, z_axis , distance https://github.com/tritdm/test

python3 position.py data.txt

Config x_axis, y_axis, z_axis

Anchor positions will have format

0, 0, 0

x_axis, 0, 0

0, y_axis, 0

0, 0, z_axis

Config TEST_MODE to False

Connect serial (remember to adjust baudrate) and transmit data, change data format to fit the use
