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 (...)

(...) 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)

(...) 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)

(...) 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)

(...) 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)

(...) I've now found that as long as I go to my junk mail folder, I can usually find the "authorize post" email. Weird, about 1 time in 5 it gets into my normal inbox, and the rest of the time it ends up sorted into "junk". (...) Yeah, I can see (...) (17 years ago, 8-Jan-07, to lugnet.org.us.laflrc)

(...) At this point, there really aren't limits on LEGO parts. Bryan hasn't posted (publicly) about his robot, but I think he's using the controller from the RC buggy for his, along with four motors. Both John and I have robots that look very much (...) (17 years ago, 8-Jan-07, to lugnet.org.us.laflrc)

(...) My vehicle does use 4 RC buggy motors. I have a motor drive assembly for each *wheel*. The drive assembly is outside the suspension components so no linkage is required. The vehicle actually uses 2 RC buggy receiver units and steering units so (...) (17 years ago, 10-Jan-07, to lugnet.org.us.laflrc)
