Thanks, Yes, it's the maximum dimensions... We have already seen the shrimp and we think to build something like that (maybe also with tri-star wheels)... But if somebody find a better solution, because we don't know the comportement of the shrimp (...) (23 years ago, 28-Sep-02, to lugnet.robotics)

The frequency of the RCX's IR does not change at all: " The RCX uses a 38kHz carrier, which is pretty typical for TV remotes. As for the sampling rate, the RCX runs at 2400 bps, which makes each bit approx 417us " (URL) think the only way you could (...) (23 years ago, 28-Sep-02, to lugnet.robotics.rcx.legos)

(...) Is that the *initial* dimensions - or the *maximum* dimensions? If it's just one of those things like "the robot must start off in a box no bigger than 30x60x30" - then it can just fold itself up into that space when they are doing the (...) (23 years ago, 28-Sep-02, to lugnet.robotics)

Thank you for your idea... but I forgot to say you that I have restriction for the dimensions... Dimensions : height : 30cm Lenght : 60cm width : 30cm And we can have 620 Euro's... Bye Vincent ----- Original Message ----- From: "Mike Thorn" (...) (23 years ago, 28-Sep-02, to lugnet.robotics)

Vincent, (...) Without knowing the limitations of your resources, I would vote for a legged vehicle. You can make if large enough that even if a leg did go in the hole it wouldn't fall in or get stuck, you could make it with as many legs as you like (...)

Hello everybody, For my university, we must construct a bot with LEGO Mindstorms. This bot has to be able to climb a step, to ride above a (little) whole and to have left and right wheels at different height. In fact, he might be able to go (...) (23 years ago, 28-Sep-02, to lugnet.robotics)

duh... guess i was kinda wrong here.. IR is in reality a frequency defined from A to B. any messages sent within this spectre is said to be IR messages. so in theory sending an IR message closer to A than B from one RCX. and at the same time sending (...)

Well, after browsing through the H8 reference another, oh 20 (?), times; and some messing around; it is now working. Basically, I had declared the Control Status Register as an 8 bit value. Since this is a special register (8 bit) that requires a 16 (...) (23 years ago, 28-Sep-02, to lugnet.robotics.rcx)

Has anyone been able to make use of the Watch Dog Timer on the RCX? The H8 documentation seems to spell out the workings quite well. BrickOS (LegOS) has minimal support (a vector is declared for both NMI and overflow) and pbForth files list the WDT (...) (23 years ago, 27-Sep-02, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos)
