I am working on a new smart ball concept. I have the equations that govern the trajectory of a spherical ball in motion. To calculate this i have two variables, Velocity vector and Spin vector. I need to measure them using sensors placed inside the ball.
Can you please help me identify if there are such sensors that can measure these variables or group of sensors that can together do the job.
Thanks
You can use a gyro-accelerometer sensor to measure the orientation of the ball in space thus measure the change of the orientation which is the spin vector along with the constant diameter of the ball you can measure the velocity
Mostafa Alakhreety Thank You very much for responding.
I am new in using sensors, so if you are able can you please explain your answer and also provide some links for some helping material.
For spin you can use some 3-axis gyroscope(it might be rather demanding on the angular rate), however you may need rather high range g acclerometer, perhaps https://www.analog.com/media/en/technical-documentation/data-sheets/ADXL377.pdf
To convert acceleration to velocity you will need to perform integration in time. That however results in zero-drift/offset problem which you need address, I am not sure it is easy to do.
Alternatively, you can employ something like Decawave (Quorvo) Real-Time Location System but that requires external receivers or transmitters.
