Hi, Skip the rambling and go strait to the pictures: (URL). After building this new set (in about 5 hours), I noticed two things that could be improved: - The boom move up very quickly and came crashing down! My first fix was to install a restricted (...)

Will the feet be required to do much rotating and/or sliding while taking a step? (I assume it (...) (19 years ago, 1-Aug-05, to lugnet.technic, lugnet.robotics)

Does anyone who makes cranes have some easy math such as geometry for crane design? The problem I see is that for a crane to be always balanced the weight in the back needs to move according to the load weight. The boom on mine bends, but when (...) (19 years ago, 1-Aug-05, to lugnet.technic)

These will do their best to accommidate the change, which may not have any affect until the (...) (19 years ago, 1-Aug-05, to lugnet.technic, lugnet.robotics)

For example, if SSC is walking forward, and it takes 3/4 of a step, then levers are flipped to make it turn (which would be reversing the legs on one side), to complete the "current" (...)
