(...) Ah - OK. But other things in the world (like people) are moving around - it's not always going to be possible to stop, capture a static image - and then reliably navigate based on it. I guess there are niches where such a robot could be (...) (23 years ago, 6-Jan-03, to lugnet.robotics)

| | brickOS with BricxCC
|
|
So far I have heard from two people who have successfully used brickOS with BricxCC. I'm interested in whether anyone else has tried using BricxCC to edit/compile/download programs to brickOS. Currently BricxCC requires that the cygwin bin directory (...) (23 years ago, 8-Jan-03, to lugnet.robotics.rcx.legos)

I'm working on a new release of BricxCC at the moment and I want to better understand the dll utility - specifically the RCX host address and RCX source port options. I think I understand the RCX host address part. Correct me if I'm wrong. Supposing (...) (23 years ago, 8-Jan-03, to lugnet.robotics.rcx.legos)

I don't have a 5292 motor or I would do this test myself, but it would be possible to get a more direct comparison with the 71427 gear motor. The 1700-RPM output could be geared down to 340 RPM at a gear ratio of 1:5 with 8- and 40-tooth gears. Tony (...) (23 years ago, 8-Jan-03, to lugnet.robotics)

Ok, here is an extrapolated result for the short circuit (stalled) test. The current at 9 volts would be 3.6 amps. Since I did not wish to burn up the motor, I checked current readings at both 3 and 6 volts and also measured the DC resistance and (...) (23 years ago, 8-Jan-03, to lugnet.technic, lugnet.robotics)

Many of the Logitec drivers will work fine with the LEGO cam (considering it's a Logitech cam to begin with). Conversely, the LEGO cam drivers work (...) (23 years ago, 8-Jan-03, to lugnet.robotics)

That figure was the normal operation (no load) figure. What concerned me was that it was a factor of almost 20 higher than the gear motors which normally run about 10mA. Of course, it is very easy to overlook the fact that the gear motor is (...) (23 years ago, 8-Jan-03, to lugnet.technic, lugnet.robotics)
