Hi, if you have a LEGO serial port IR-tower and and you also got a RoboSapien, you can now easily control it from the PC. (URL) to Linux and USB tower coming later...) Feedback is appreciated. Enjoy, Pavel. (19 years ago, 6-Jul-05, to lugnet.robotics.rcx.legos)

(...) You don't need advanced math for navigating, but sin and cos for calculating coordinates in an X/Y coordinate system. This you need independently from your steering system.

Hello, according to informations that brickOS is the most powerfull of all Mindstroms OS's, I have tried to start it. I work with a Linux 2.6 (Fedora Core 3). I have compiled it with rcx-egcs cross compiler C and C++ cross compilers (version 1.1.2) (...) (19 years ago, 19-Jun-05, to lugnet.robotics.rcx.legos)

(...) We have worked with a big chart with black crosses on a white wooden surface. This works pretty well, since with the reflection of the light of the LED, black and white can be easily recognised. Then the ambient light has not a big influence. (...)

(...) From something I read 12 years ago for my university project (a Lego robot of course, but pre-RCX), I think it required differential equations (ugh!). Probably a bit too memory-hungry for an RCX. Perhaps you could use the PC's computing power (...) (19 years ago, 26-May-05, to lugnet.robotics.rcx.legos)

Thanks Thomas for your idea. The matter is that I was thinking of using angle sensors in order to calculate the number of the turns that each wheel has driven (I am talking for a robot with 2 wheels). I think that some advanced maths are required (...) (19 years ago, 26-May-05, to lugnet.robotics.rcx.legos)

(...) In theory you can find position by having a 'giant pantone chart' on the floor - a sheet of paper like the test pad with coloured squares on it, and use the light sensor to detect which square the robot is on. Has anyone tried this? It will be (...) (19 years ago, 25-May-05, to lugnet.robotics.rcx.legos)
