Hello People I am working on a project where we are trying to use a compaq handheld with linux and a wireless card as the "brain" of robots. "Underneath" we have an RCX acting as a "spine", which is supposed to receive macro commands from the PC and (...) (23 years ago, 21-Nov-02, to lugnet.robotics.rcx.java)

(...) I was under the impression that a 6 head video recorder was a marketing concept, i.e. it has 4 video heads and 2 audio heads, so in this case (all things being equal) it would be exactly the same as the 4 head one. This is really what I've (...) (23 years ago, 21-Nov-02, to lugnet.robotics)

(...) Here I go, tossing my 2 cents in to the fray: I would say that any differential drive on a flat surface has 3 DOF: -Assume it drives along the X axis (thats 1) -it can rotate around the Z axis (2 now) -once it rotates it can drive along the y (...)

Andrea, Excellent model! Nice to see someone else also constructed a mixer truck. Seems that your model is fully operational. Did you have to cope come difficulties with the drumm? (shape, connection, motorization etc.). I'm curious to your next (...) (23 years ago, 21-Nov-02, to lugnet.technic, lugnet.robotics, lugnet.general, lugnet.modelteam, lugnet.loc.it)

(...) The trouble with this is that it's not necessarily true. Take 100 Lego turntables and connect them up into a vertical column. By this measure, it has 100 DOF - but as a mechanism, it has no more flexibility than a single turntable (1-DOF). (...) (23 years ago, 21-Nov-02, to lugnet.robotics)

(...) Yes. (...) Depends a lot on how much work your robot is doing. If it's just running the computer with no motors or sensors turned on - then probably 12 hours. If you are running lots of motors and sensors then it's more like 3 hours...but it (...) (23 years ago, 21-Nov-02, to lugnet.robotics)

Nick, Setting the timeslice to a low number (5ms is fairly low), negetively effects overall system performance. Time used by the operating system for task switching is taken away from applications. If a switch takes .5ms (for example) and you switch (...) (23 years ago, 21-Nov-02, to lugnet.robotics.rcx.legos)
