(...) That is the exact thought I had the last time I was at your place and saw the alternate model for the semi tow truck sitting there. Nice to know great minds think alike ;) But being short 1 semi-tow truck, I can't do that at the moment. John (17 years ago, 8-Jan-07, to lugnet.org.us.laflrc)

(...) Well look whose back to being able to post on LUGNET :) As to rotating the motor, that would require either elongating the wheelbase, or raising the NXT up to make room. Neither option is desirable. Raising the NXT puts the COG too high, and (...) (17 years ago, 8-Jan-07, to lugnet.org.us.laflrc)

(...) Brian, This sounds like a good suggestion. How is your rock crawler progressing? :) I actually spent last night working on a transport vehicle for my Rock Crawler. Hopefully, by the end of the week, I'll have an RC hauler that can be used for (...) (17 years ago, 8-Jan-07, to lugnet.org.us.laflrc)

(...) Very nice! I like the compact rear differential and gearing. I wonder if you could rotate the rear motor 90° so it lays under the chassis, to (very slightly) improve the center of gravity. Very nice looking. What happens if it gets lifted at (...) (17 years ago, 8-Jan-07, to lugnet.org.us.laflrc)

I think we need to have another meeting. Mainly so I can test this... (URL) links (URL) suspension or rear steer in this one, but it is 4wd, with both axles linked so all 4 wheels will spin before the motors stall, and it can climb a sanded plywood (...)

It appears Science Central has added this year's First LEGO League challenge to their list of events for Feb 24th. So, for those of us who've been playing around with the idea of building a robot, here's your chance... (URL) (17 years ago, 2-Jan-07, to lugnet.org.us.laflrc)

(...) That's how they do it in "real" rock crawling. It will be a little different for us, because you don't actually have to "put it into reverse". I think having a penalty for backing up may be good. In the "real" event, there is also a penalty (...) (17 years ago, 2-Jan-07, to lugnet.org.us.laflrc)

Steve, I just had a thought on scoring. You mentioned that you wanted to make the course tough enough so a perfect score (no penalties) would be nearly impossible. How about giving a penalty every time someone backed up? I can't remember a single (...) (17 years ago, 2-Jan-07, to lugnet.org.us.laflrc)
