accelerometer and gyro plotting movement?

Other Hardware Sensors

I'm trying to figure out if I can plot the 3d movement of a hand held object over a 1 second period. the object starts from a stationary point then moves on an arc a little bit like a hammer. once the movement has stopped I want to be able to plot the movement in space. Would it be feasible to use an Accelerometer and gyroscope to acheive this?

Theoretically, if you can read the devices fast enough, you could record a list of vectors[direction, acceleration] that could be summed to generate the resultant. The question is of course how fast you can read, and how accurate these reading are.

If the object is spun, all bets are off. Now the gyro angular readings would have to be used to null the centripetal acceleration.

If you can read and sum the vectors at 1khz maybe it would be accurate enough, at 10hz probably not.

thanks Chuck, that's pretty much what I guessed, I don't envisage much rotational spin.

There is an example of what I would like to do here GitHub - xioTechnologies/Oscillatory-Motion-Tracking-With-x-IMU
however it uses very expensive hardware I was thinking I could achieve something similar with a Bosch BNO055, which has onboard maths.
