Medieval 2-Wheel Drive

thingiverse

We've all seen those super-cool, tough-to-print & assemble, 3D vehicles... Thinking of working with tinier hands & attention spans, the mission for this holiday season is to see just how simple I might make a powered driving experience. To keep things as simple as possible, the technique demonstrated here is how - whenever we see forward motion in one direction - that the exact same direction of motion can be found, in transition. One forward clockwise, the other forward, counter-clockwise. Equal yet opposite: 'Tre Newtonian? 0:-) So whilst the need to demonstrate the same made for an eccentric wheel alignment, I am looking forward to seeing what you might be inspired to share with the rest of wee gear-geeks, out here on the 'nerd-a-net. =) Come to think of it, if I was going to make a cart using hewen logs, this is how I would have done it ... Was not too surprised to discover afterwards - when a 'pop historian reviewed a medieval mileage machine, declaring the be-geared movement impossible -- that it works just fine! Misc: * The "TopBox" is designed to hold your battery. Print with support. * The motor is the same metal-geared N20 that we used on the Mark I Tri-Rover. ( https://www.thingiverse.com/thing:4002840 ) * Add a rubber-band or four (#32) for tractions. We used epoxy to keep them. * Extremely tight fitting, but it will snap together w/o glue. Thine rubber mallet mayest come in handy, methinks.
