The Armbot - Let me shake your hand!
This is an arm. What's more, this is a very proper, polite, and otherwise well-mannered arm. I have taught this piece of plastic to shake your hand, when it sees you near it, ad to wave good-bye when you leave. It can sense when you're shaking its hand, and if you say something, it wqill reply. It is my third Armbot, and so far my best. On all of them, the shoulder kept popping off, and it twised your hand. The hand wasn't very comfortable, and the wrist kept popping off, too. the shoulder wasn't strong enough, and it was very jerky. All of them, that is, exept this one. I solved several problem with the shoulder with this arm. On the last one, the stationary arm that wa connected to the nxt was the one that raised the shoulder. this made the rather large shoulder into a reverse third-class lever, for those of you who know what that is. In short, it made it work harder, which I didn't want at all. In this design, the stationary arm SWINGS the arm, not LIFTS it. this make the shoulder into more of like an axle, and the former swinging arm raised it, having it lift only what it had to. The shoulder is also more securely attached this time. The main pic is a full-view of the ArmBot, pic 1 is the extents that i had to go to to keep the shoulder attached, pic 2 is another view of the arm, pic 3 and 4 are pictures of the hand, which is actually quite comfortable. The hand has the touch sensor right where your thumb would normally go, and a little bar so that the wrist moves with the rest of the arm. I'm working on a Program for is, as well as an LDD so don't bother asking.

  • Does the whole arm use one NXT set? Because otherwise I can't build this project and I really want to. An LDD would also be helpful.

    What exactly do you mean? The arms uses pieces only from the NXT set, but not all of them. The arm uses a pretty good part of the retail set, but there still are lots of parts left over.

    For all of the people who have asked for videos and ldds, I made this robot before I got my video camera or downloaded ldd. Sorry.
