I don't know of any other source for the flex axle. I found that they did not turn smoothly. Tend to loft. Maybe they can be contained at several points to stop the whipping action. Micromotors seem to work well in pairs, I guess they unlock each (...) (23 years ago, 10-May-02, to lugnet.robotics)

(...) You should be able to get 3 sensors to control 3 motors like this: Sensor A not pushed = forward Sensor A pushed = reverse Sensor B pushed and not C = Motor 1 Sensor C pushed and not B = Motor 2 Sensor B and C pushed = Motor 3 -Kyle (23 years ago, 10-May-02, to lugnet.robotics)

(...) Thats the exact problem I'm having. I would like to have 1 RCX be able to control the direction of 2 motors. So what I trying to make is a 4 button controller using 3 touch sensors. For instance, I want to have 1 RCX control the opening and (...) (23 years ago, 10-May-02, to lugnet.robotics)

(...) Yes - I agree. I'd avoid using micromotors anyway because of their tendancy to lock up when you put any kind of strain on them. Micromotors are good for little decorative features or small one-time operations that don't need much power. So (...) (23 years ago, 10-May-02, to lugnet.robotics)

(...) I've used a collection of four Scouts driven by IR commands from an RCX to drive a total of eleven motors. Just program the scouts to read simple 1-byte messages sent from the RCX - use the top two bits to select which Scout you are talking (...) (23 years ago, 10-May-02, to lugnet.robotics)

I am not a big fan of Lego pneumatics either, but they are so light weight and a perfect solution in your application. The micromotors have so little power, that you would have to gear them down to get any holding power for your grippers. Then (...)

(...) Don't know. Just made a quick download from sourceforge. Didn't install, just looked through with mc. Seems that in the mint-lib, both cmp2-files are missing. And no printf in the c library path. Regards, Michael (23 years ago, 9-May-02, to lugnet.robotics.rcx.legos)
