| (...) Try Google with "hopping robots" or "jumping robots" for a start. I think you might have difficulty getting a Lego-only robot to jump, though. It's hard to get enough force, and just as hard to "wind up" to build enough force to launch an RCX (...) (23 years ago, 20-Nov-02, to lugnet.robotics)

| | | | | 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 (...) (23 years ago, 20-Nov-02, to lugnet.robotics, lugnet.build.mecha, lugnet.technic)

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.

| | | | | Re: articulation points?

| 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. (...)
