... is there any chance you could share these walking motion sequences files so that I could somehow translate it into Bioloid Motion file?


Hi Mic, any luck with that?, I mean if you was able to use the wallking sequences from cosa (witch are greats btw) with a regular motion file?

also kind of confuse here, the cosa movements are calculated by a s-curve and then values send to the servos step/frame by step/frame right?

thanks..

ok thats your answer limor?, I know that link and it is a very usefull collection of links for severall bioloid resources, but I made a specific question about the cose wallking motion sequences using a regular motion file, can you tell me where is the answer to that in the link?

Well, there is the information or the knowledge

"how to use the motion sequences from cosa with regular mtn files" is probably your work or the work for anyone thta is interested in it...

Amateur robotics is still very much a 'create your own solution'. I doubt anyone here has yet got motion files working with Cosa's software. It'll be down to you to try to patch bits of software together.

Thanks StuartL, sure I going to make the bits that I need, just asking in case it was allready done..

In cosa's plots I believe the axes are servo position on the vertical and time interval on the horizontal. If timing is as it is in the CM-5 then each interval is 7.8ms.
