Popular Post Giles Posted December 19, 2020 Popular Post Share Posted December 19, 2020 There isn't really a topic for automation per se, so in Modelling Musings seems as good a place as any. I've been having a play with the concept of people moving. Not just the arm moving or whatever, but whether anything much more is possible (leaving aside the question of whether it's desirable or or not for another time.....). Not so much because I want a figure striding down the street particularly, but someone might, and also, when you find a way to do things, it very quickly opens the way to doing other things you hadn't even thought of...... I considered a moving track underneath the baseboard in a similar way to the magnetic cyclist, but of course it becomes much more complicated when you have two feet stopping and starting alternately. Also, do you have magnetic connection or a mechanical linkage? I came down of a self-powered under-baseboard tractor, which is geared to the same speed as the 'step' , so one foot will always appear stationary to the ground as the other advances. 1 28 5 Link to post Share on other sites More sharing options...

That's actually quite spooky! 1 Link to post Share on other sites More sharing options...
RMweb Premium Dave John Posted December 19, 2020 RMweb Premium Share Posted December 19, 2020 A very impressive demonstration. 1 Link to post Share on other sites More sharing options...

RMweb Gold Happy Hippo Posted December 20, 2020 RMweb Gold Share Posted December 20, 2020 Many years ago there was an article in the 16mm NGM journal about making a man that pushed a slate wagon along. It looked quite realistic, but was achieved by the legs being jointed at the knees. When you see someone walking, there are lots of individual joints working in unison which is incredibly hard to recreate in such a small scale. What you have achieved so far would certainly work if the subject was hobbling back from his Spitfire. 1 1 Link to post Share on other sites More sharing options...
eastwestdivide Posted December 20, 2020 Share Posted December 20, 2020 Would the effect be improved if he was leaning forwards just a couple more degrees? Hard to tell against the background, but I got the impression he was tilted back a little. Pretty impressive though! Link to post Share on other sites More sharing options...
Giles Posted December 21, 2020 Author Share Posted December 21, 2020 He could tweak forward a couple of degrees without problem - he's about vertical at the moment. The chap pushing the wagon was driven with a mechanism in the wagon, and relied on him 'leaning' whilst pushing - very clever it was This version could certainly be done in 4mm, but of course it has the inherent drawback of the Scalectrix slot required..... 1 Link to post Share on other sites More sharing options...

Giles Posted December 23, 2020 Author Share Posted December 23, 2020 New cams fitted to reduce the step slightly, and this is now about as good as I can make this method work. 3 7 Link to post Share on other sites More sharing options...
Giles Posted December 30, 2020 Author Share Posted December 30, 2020 Grass is the best medium I've found for disguising the slot he needs to walk in. This is it, experiment concluded - it is possible to have walking people, though it's complicated. It can be done in a straight line or a curve. This is 7mm, but a 4mm version would just mean changing the cam wheel and the drive wheel and putting a smaller figure on...... I shall be interested to see if anyone ever does anything similar. 2 2 1 Link to post Share on other sites More sharing options...
