(...) Thanks Ross. Hopefully the outriggers will not give way. I used the diagonal outriggers to minimize the complexity of the crane mechanisms, but they may give way under the wieght. I hope it is as good as your designs! I just realized (...) (19 years ago, 2-Aug-05, to lugnet.technic)

(...) Hi Nathan, looking good! I wish I could be at Brickfest to see it. WRT balance, the answer is that cranes are very rarely in total balance. That is why they need such strong accurately machined turntables - the turntable is generally taking (...) (19 years ago, 2-Aug-05, to lugnet.technic)

I have not finished the feet, but I was planning on providing an ankle that rotates about the Y axis, so that foot rotation is limited. A certain amount of sliding is expected. (...)

(...) I should say it would look more 'natural'. How easy will it be to install a normally closed (while the foot is in the air) touch sensor in the foot? 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)

(...) No. The central timer is unchanged by switching from forward to reverse, or walk to turn. The things that do change behavior are the leg sweep pistons. 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)

(...) Will it be necessary to switch anything at a specific time? 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" (...)
