A Matlab toolbox/program for processing IMU data using a Kalman filter based zero-velocity aided INS algorithm has now been released. The framework allows the user to process the IMU data using different error state space models and zero-velocity detectors. The OpenShoe C implementation is a special case of the possible settings.

Thursday, December 15th, 2011SSH problems — no upgrades
Thursday, December 15th, 2011We are currently experiencing some local problems with SSH service. This mean that a lot of code and documentation has not been upgraded lately. The SSH issue should be resolved by tomorrow (has our computer support told us) so then we should be able to update all repositories.
Casing Rev 2
Friday, December 9th, 2011Today we got a batch of updated casings:
The casings are essentially the same as the old ones. The changes we have made are:
1) Changed some tolerances to make things fit without adjustment.
2) Made the lid 0.5mm thicker to improve the mechanical stability.
3) Added holes to the bottom identical to those on the top to make it possible to screw it to something (if needed).
4) Changed the placement of the exit hole for the cable to the middle of the side to make it symmetric for left and right foot shoe integration.
5) Some minor changes such as edge rounding radius etc.
