Hi Zenta.

I have one question.

When phoenix doing roll from initial stance, does the coxa servo rotate also or

just femur and tibia?

Thanks

[ZentaOlbaid]

@gonzo110391 All servos rotate. But if one leg, ex. the middle leg are positioned perpendicular to the roll-axis the coxa servo won't rotate.

@ZentaOlbaid

One more Zenta, when we have obtain the Rx(alfa)*Rz(beta)*Ry(gamma) rotation matrix,

what we're going to transform with that matrix? The coxa position or the tip of the tibia position ?

I guess it has to be the coxa because the tip of tibia must stay still.

I've spent hours try to understand rotation kinematics and rather confused.

Sorry for the silly question

Thanks

@gonzo110391 Its the tars (tip of tibia). If you've more Q's I would suggest that you join the Lynxmotion forum. :)

Excellent body movements while walking! Nice work!

how long have you been working on that?!

just wow o.0

that is some kewl but creeeepy stuff.

[alexjr2424]

woah! that's AWESOME!!!!!! btw, doesn't that thing look JUST like the scarab from halo 3? not saying that's a bad thing, but that's INSANE!!!!!!
