| (...) Here I go, tossing my 2 cents in to the fray: I would say that any differential drive on a flat surface has 3 DOF: -Assume it drives along the X axis (thats 1) -it can rotate around the Z axis (2 now) -once it rotates it can drive along the y (...)

| Andrea, Excellent model! Nice to see someone else also constructed a mixer truck. Seems that your model is fully operational. Did you have to cope come difficulties with the drumm?

So here it is: (URL) like how the Toa and Bohrok foot came together nicely to form the mouth without too much effort. And the red flag was (...)

| | | | | Re: articulation points?
|
| The main reason it would make sense to quote the total DOF is that is determines the volume the arm needs or is able to work in. For example imagine a snake-bot with a dozen 2 DOF joints. It can reach around objects to position it's effector. So it (...) (22 years ago, 21-Nov-02, to lugnet.robotics, lugnet.build.mecha, lugnet.technic)

| | | | | Re: articulation points?
|
| (...) I think you've hit the nail on the head here Eric. To me, the most logical way of looking at a robot arm would be from the point of view of the end effector, i.e. what it can and cannot do. The way the arm moves to get there may be of less (...) (22 years ago, 20-Nov-02, to lugnet.robotics, lugnet.build.mecha, lugnet.technic)
| | | | | Re: articulation points?
|
| (...) 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 (...) (22 years ago, 20-Nov-02, to lugnet.build.mecha, lugnet.technic, lugnet.robotics)

| 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 (...)

| (...) 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. (...)
