| (...) Very interesting thread. A bit OT (and picky ;) mabye, but about the human arm: If you examine your arm closley you'll find that the rotation of the hand actualy comes from the elbow witch rotates the under arm. The wrist only actes as a dual (...) (23 years ago, 20-Nov-02, to lugnet.build.mecha, lugnet.technic, lugnet.robotics)

| Not to be a goof, but, OMG! Bram is Crazy Smart! I gotta go a take some more vitamins and drink Carrot Juice! Ahhh! I see the concept much the same, I figure if we refer to a POA in a Mecha model as the counting scheme, we won't get alot of run away (...)

| You present interesting aspects of the term, could it be that the term has many meanings and really if we understood it correctly we would do justice to the proper meaning. Context is everything, yet you raise ideas and examples that indeed (...) (23 years ago, 20-Nov-02, to lugnet.robotics)

It's pretty interesting, although I never really thought about it seriously before, I just build stuff. ;) (...) Well, more so (...)

| o.k. so let me get this right: poa doesn't necessarily dictate dof. poa refers to the axes a given object can rotate around, but dof refers to the limitations (or lack thereof) in space a given object can move around in. according to eric, i may use (...)

| Everything I've ever seen mentioning DOF refers to absolute reference points (a focus, if you will, or origin) that the range is controlled by. In terms of articuation, each DOF corresponds to a joint, which is a fixed focus point that the range (...) (23 years ago, 20-Nov-02, to lugnet.robotics)

| (...) However, a device is made up of several objects. Each component, if treated separately, has six degrees of freedom. Thus each component of, for example, the human arm (reduced to an upper arm, lower arm, and hand) has 6 DOF, for a total of 18. (...)

| (...) Oh? Hmmm...do tell. (...) Right! I see. In my own way I work around certain "movements" or joints by making two separete joints cover the same envelope or Area or Control. I mean in that, for example. The Arms of my Super Mech-Bot don't have (...) (23 years ago, 20-Nov-02, to lugnet.build.mecha, lugnet.technic, lugnet.robotics)

The maximum number of degrees of freedom an object can have in three dimensional space is six; translation in the (...)
