| (...) That, to me (and according to all definitions I've seen) is "range of motion". However, without DOF's, an effector couldn't be positioned. (...) The more DOF's, the better the overall control and positioning *could* be. In the case of the (...) (23 years ago, 20-Nov-02, to lugnet.robotics)

|
| (...) Yeah, I missed that, I'll add that to the notes. (...) Too bad they didn't document the hole well enough to make it obvious to the people at Lego, who apparently had no idea. They use "mov.w rx,@0xf000:16" all over the place instead of the (...) (23 years ago, 20-Nov-02, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos)

| (...) Thanks for the suggestion... I think the change I made a few days ago included a note here also, but we might be talking about different spots. Let me know if not... kekoa@stanford.edu. -Kekoa (23 years ago, 20-Nov-02, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos)

| 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 (...)

| | | | | LegOS/BrickOS on Mac OS X?

| I was wondering if anyone had successfully ported the H8 compiler over to OS X? With an USB IR Tower, and the underlying Unix/BSD resources on the Mac, it would be an ideal development platform. I've tried compiling the H8 Cross compiler without (...) (23 years ago, 20-Nov-02, to lugnet.robotics.rcx.legos)

| | | | | Re: Jumping robot
|
| (...) 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)

|
| (...) 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)

| 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 (...)
