| (...) Yes, that was the problem Brian was having. And, because the LEGO motors are so efficent, they work really well as generators. So, if you hook two together, and try to turn 1 and stop the other, you will have problems. I'm not sure I explained (...) (21 years ago, 25-Nov-03, to lugnet.robotics.rcx)
| | | | | Re: Weird downloading error
|
| Just some general ideas. If you're not using the firmdl or lejosfirmdl that came with lejos, try using one of those. Some versions of some downloaders have trouble with the lejos firmware. If you haven't tried fresh batteries in your RCX, try that. (...) (21 years ago, 25-Nov-03, to lugnet.robotics.rcx.java)

| (...) I'm just thinking out loud here, but it seems that the problem with the two middle motors is that they are wired together. So even if the RCX is told to float the motor output, both motors will want to turn together. If one turns, it will act (...) (21 years ago, 25-Nov-03, to lugnet.robotics.rcx)

| (...) Well, I've never actually tried running six motors directly from the RCX. However, I have used three motors to drive a sumo robot. And I've also used four motors (two on each side) to drive six wheels (two on the right, two on the left, and (...) (21 years ago, 25-Nov-03, to lugnet.robotics.rcx)

|
| Hello ppl, I have this weird problem where I can't seem to download the lejos firmware completely onto the RCX. The counter on the RCX lcd counts up to 20 as the firmware is downloaded while the LCD also shows a weird 'V' sorta symbol on the far (...) (21 years ago, 25-Nov-03, to lugnet.robotics.rcx.java)

The devices have a power supply that is basically a big cap and a (...) (21 years ago, 21-Nov-03, to lugnet.trains, lugnet.robotics.rcx.pbforth)
