 | | Recommendation for a robotics set.
|
|
Hi all, I am new to Lego, but from what I have seen and read in the newsgroup it seems an easy way to have some fun with robotics. I am getting a HandyBoard as a brain and I wonder which is the best set to get started, something with lots of gears, (...) (25 years ago, 29-Oct-00, to lugnet.robotics)

(...) While not directly related to Lego Software, ME *REALLY* slows down the machine. They must have used blocks of LEAD in their code... I'd recommend against it. Dean -- Coin-Op's For Sale!: (URL) Lego Workshop: (URL) Lego Club: (URL) (25 years ago, 29-Oct-00, to lugnet.robotics)

| | const int syntax
|
|
I cannot seem to find the right syntax for const int in NQC. For example, in trying to synchronize LEFTLEGS and RIGHTLEGS in a 6-leg robot, this piece of code does *not* work: int count; //declare a variable 'count' count = 0; //initialize 'count' (...) (25 years ago, 29-Oct-00, to lugnet.robotics)

Thanks to the efforts of a number of people, there is a raft of new documents up at the legOS site. Because of the growing amount of documentation, I've organized a new page to keep track of all the available docs: (URL) things up there now: *LegOS (...)

I'm new to this newsgroup so I don't know if this has already come up, but is the vision command camera the same as in the movie maker set? (25 years ago, 28-Oct-00, to lugnet.robotics)

(...) This is certainly true - but when I think "I need more I/O" - I also think "I/O should be modular and infinitely expandable". I don't want *any* practical limit to the number of motors and sensors. A mere 'Mark II RCX' with (say) 5 inputs and (...) (25 years ago, 28-Oct-00, to lugnet.robotics)

The approach I would take would be to use a splitter (ratchet or worm) and make one output shaft a gear selector for a transmission, and the other shaft the input power for the transmission. The transmission design would be tricky, because the (...) (25 years ago, 27-Oct-00, to lugnet.robotics)

I don't know if this will help, but i'm currently working on a device that lets one motor drive four seperate axles. Downside is that it's one direction only, and only one axle can be used at one time. Howerver, you could use an extra gear to make (...) (25 years ago, 27-Oct-00, to lugnet.robotics)

(...) I think it would be very difficult to get workable bidirectional control of 2 things from one motor. However, it is quite possible to multiplex motors so you can do many more then 2 things from 2 motors. For example, you can have one motor (...) (25 years ago, 27-Oct-00, to lugnet.robotics)
