COSMEcopter. Prototype P04

Almost a year and a half ago, COSMEcopter was presented in this blog. During all this time a few preliminary prototypes have been developed. Now we are currently working in prototype P04.

P04 is a substantial milestone in the project. It can be described with these three points:

• RQ01: "the thing" shall be able to elevate a few centimeters above the ground, 
• RQ02: it shall be able to stay stationary for a few seconds
• RQ03: it shall be able to land softly (that is: without crashing)

COSMEcopter attached to the "jamonero", ready to perform another batch of One Axis Integration Tests.

Well, only three short one-line-requisites shouldn´t be very hard to achieve, should they?

By now, Eugenio Alcalá is struggling with a series of one axis integration tests, where two motors are running in a coordinated fashion for the first time in the project.
This test is meant not only to validate the control algorithms, but also to answer an even more important question: Is the realtime performance of the combo "Raspberry-Pi-computer + Linux-Preemptive-RT-kernel-patch" good enough for this kind of tasks?
