The chain is not necessary. It was just a quick way of hooking the motor to the differential. There is sometimes a delay in the system because the pump is such a small load even when the valve is closed. One way around this is to give the output (...) (14 years ago, 11-Aug-10, to lugnet.technic)

Hello Nathan, Is there a technical reason you use a chain link between the motor and the differential grear? Would it be unsave to engage the gears directly in this case? With friendly greetings, M. Moolhuysen. (14 years ago, 11-Aug-10, to lugnet.technic)

I haven't posted in this forum since 2008 and haven't built much, but upon looking at the new 8043 Excavator set at Toy's R'Us, it became apparent that although the new linear actuators dramatically simplify the process, they are not the only (...) (14 years ago, 10-Aug-10, to lugnet.technic)

(...) There exist programs (not sure where) that can convert a video file into a series of still images. From there, it could be converted into a set of building instructions. (14 years ago, 17-Jul-10, to lugnet.technic, lugnet.robotics.cybermaster)
