Hi FP. I was watching old youtube videos, had an idea for a contest. I’m not going ahead yet, just throwing the idea around, seeing if people like it.
Amphibious car Mk II
Basically, it’s, well, an amphibious jeep (think schwimmwagen or seep). It has to be able to offroad decently, and race around a land/water track. The track will have timer, obstacles like a vehicle test course, etc. I’m right now working on a track. Judging is whoever is fastest.
The really simple rules
1.) Must be wheel/angforce/torque/engine/hamster powered. This means no cars able to go airborne (this will also limit speed and make it a bit more difficult)
2.) Maximum unparented weight is five tons (5000). Do whatever you want to your parented props
3.) Must be able to make it over basic obstacles on the course (so you’ll need decent off-road performance)
4.) The method of propulsion in water must be derived from the wheels’ propulsion (no separate motor). Wheels with water-cleats are ok although they may fuck up on land, and any linkage that connects the wheels’ power to that of a propellor, etc, is OK. (This is not hard, a simple linkage, propshaft, or gearing will do it. Look upxro’s excellent rope engine if you need a non-geared way to transfer rotational power 90 degrees)
5.) No Bouyancy tool–100% old-fashioned engineering needed. setMass() is allowed.
I can finish up a nice race/obstacle track real quick. Just throwing it out there, if ppl like the idea, I’ll change the post to “we have a contest!”
