 | | Gearing down a lego motor
|
|
Hi, Before I invest a lot of time on this, what is the minimal gearing I need to do in order for a Lego motor to let itself up. How about a lego motor lifting itself and another motor up? I want the motor to be powerful but at the same time fast... (...) (24 years ago, 20-Jan-01, to lugnet.robotics.rcx, lugnet.robotics)

(...) I cleaned up my code (found one bug!), the patch follows. As you may see now there are two semaphore, because two are the resources to give access to: the LNP buffer and the IR port. I modified the calling of the handlers to avoid race (...) (24 years ago, 20-Jan-01, to lugnet.robotics.rcx.legos)

| | Vison Command & W2K
|
|
I bought a Vision Command set and found that the LEGO software installer detects NT & 2K and refuses to go further. However, the CD for VC has 2k drivers and the QUICKCAM program works fine. Anyone have a way around this problem? (24 years ago, 19-Jan-01, to lugnet.robotics.rcx)

(...) With regards to this, it appears that Markus left out two necessary functions in lib/mint. Specifically, cmpsi2 and ucmpsi2.

| | Another way to avoid Float
|
|
For the navigation of my robot, I do not plan to use float or trig function. I will use long integer (32bits). the high 16 bit are the true integer value. the low 16 bits are 1/65535 value. let say 1 = 0x00010000 2 = 0x00020000 2.5 = 0x00028000 2.25 (...)

|

to overcome limitations of the prog. size in my CM, and my experience with Java, I decided to have the applications running on the host laptop. In the mean time things are looking very good. I'm only running Java on the host. I didn't touch the CM. (...) (24 years ago, 19-Jan-01, to lugnet.robotics.rcx.java)

| | legOS v2.5 merge-map utility still using perl ?
|
|
I read somewhere that perl was no more needed in v2.5. And as I began with this v2.5 version, I didn't install perl. So when I try to use merge-map to get a symbolic disassembled file of my code, it fails. Should I install perl or is there any way (...) (24 years ago, 19-Jan-01, to lugnet.robotics.rcx)
