Crane Loader LEGO GBC 

The original had problems with loading balls where the loading time would be too short. This is also solved by the cam and clutch timing system. The sometimes jittery motion at the start of the movement I hope to overcome with a bit more tweaking after an event day by gathering more experience with the module.

I think the cause of the jittery motion is the better application of power. I built the type 1 before I did the gearbox for this one, and found that a lot of power was lost in the old version. Over time too, that became jittery as friction became an issue. Another aspect is that this version runs faster then the old type 1 so a reduction in torque is seen. I will admit its more jittery then I had expected. Its also worthwhile to note that in changing the geometry I found that the rubber wheel had to be removed from the rim that rides on the cam, as the new geometry somehow lowered the ball container more then the old one (and now the geometry didnt work). Perhaps removing the rubber part reduces the absorption over the bumps in the cam. Perhaps Its worthwhile to re install the rubber tire.

Yes, only one Powerfunctions M motor in the train and mechanical switches. The building instruction is for free, no Mindstorms in there. I will make a video soon with more explanation on how the train system works.
