Using quat output from Sentral chip

Question

Using quat output from Sentral chip

Opened this issue 6 years ago · 12 comments

Hi Kris, I want to do find the rotation from quat1 to quat2. I used some standard lib like pyquaternion but got wrong result. When I use your function to convert from quat to rpy and rads, everthing is good. So it seems like the quat output from Sentral may have something special that makes it not working with pyquaternion. I wonder if you can give us some pointer to solve this problem. More specifically, we need to operation: quat multiplication and inverse. Thank much.

Not sure what the trouble is, except that maybe you need to make sure which is Qw and which is qxyz? Maybe these are reversed or something.

True, the output of Sentral is qxyz, qw, which seems to be reversed of standard normal.
BTW, can you share with us the reference to your formula to calculate rpy from quat? Thanks.

Hi Kris, do you have discount if I buy 10 items? We want to created a glove like this one. We want to do it by ourselves first. Appreciate any advice. Thank you. On Fri, Oct 26, 2018 at 10:19 AM Kris Winer <notifications@github.com> wrote:

I can offer 10% discount, so buy 9 get 1 free if you pay direct via paypal to tleracorp@gmail.com. Please include US shipping $3.50 or Internaltional shipping $14.95. Please send your shipping address including phone number. The EM7180 breakouts have only one I2C address so it will require an I2C multiplexer to get data from 10 of them on a single I2C bus. Also, this is new and might help: https://github.com/gregtomasch/EM7180_SENtral_Calibration On Sun, Feb 24, 2019 at 8:26 AM robotdreamers <notifications@github.com> wrote:
