1.is it possible to substitute the new type flex system connectors for the old type? and 2.does anyone know a good current substitute for the Tyre 20 x 30 Balloon Solid from set 8074? Will the Tyre 20 x 30 Balloon Medium be a sutable substitute? (22 years ago, 22-Nov-02, to lugnet.technic)

(...) 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 (...)

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)

i never really gave it a thought about the hand not having rotation of its own accord, but rather gets it from the elbow. that solves a huge problem i'm having with my mech. you see, i'm having difficulty with my mech holding his weapon because it's (...)

(...) 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)

(...) 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.

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. (...)
