(...) I'm not so sure about motor design, there are quite a few motors that block (one in ten for me). Since wou use RoboLAB it may rather be the LEGO firmware that protects your motors, it contains code to limit the speed of switching the motor. (...) (23 years ago, 27-Apr-02, to lugnet.robotics)

| | 4 Legged Robot; Steering Help
|
|
I am working on a project to build a 4 legged robot. The legs will be fairly articulate although I have not yet figured out how to turn a 4 legged robot. I have read information suggesting to put a turntable in the body, but without a working model (...) (23 years ago, 20-Apr-02, to lugnet.robotics)

I have yet to see a single problem with RIS 2.0 software on Windows 2000. I have done VB development with the tower/rcx on the same platform. I have used exclusively Windows 2000 for all of my development and robotics without any problems. The only (...) (23 years ago, 27-Apr-02, to lugnet.robotics)

(...) The 'on-brake-on' method of speed control is VERY useful. When implemented it looks and acts like a stepping motor. For an example, go to my website at (URL) and navigate to my Injection Molding Factory. There is a motorized air valve with a (...) (23 years ago, 26-Apr-02, to lugnet.robotics)

(...) Oh, it probably does have that option; if nothing else, you can change the code to do it that way. I simply find the ON/BRAKE modulation to be more useful, so haven't bothered looking for an alternative. - Alex (23 years ago, 26-Apr-02, to lugnet.robotics)

Wow! I hope LegOS has the option to use On and Float too. I was planning on migrating to LegOS soon, but if it does On and Brake, it is to be avoided. That technique simply burns battery power! JB (...) (23 years ago, 26-Apr-02, to lugnet.robotics)

Fredrik, I notice you are planning on using MATLAB/Simulink for simulating transition diagrams and testing your design. Did you know that if you have Real-Time Workshop you can generate auto-code for the MindStorm it self without having to recode or (...) (23 years ago, 26-Apr-02, to lugnet.robotics.rcx.legos)

(...) The standard firmware does pulse-width modulation alternating between ON and FLOAT. What I think Jerry is suggesting is pulse-width modulation alternating between ON and BRAKE (which does control speed quite handily, and is what legOS does). - (...)
