All these posts about big outdoor GPS robots has me thinking about various chassis designs. I'll bet many of the "kids" here (born 1970 or later) have never seen the 6x6 amphibious Amphicat (circa 1972), let alone an AmphiCar!

Amphicar: The front wheels act as rudders!

    In the second video where they pull out of the water....

    ...is the ramp at Tega Cay Marina. I own Tega Cay Animal Hospital, so you could say it was filmed in my "back yard" on Lake Wylie.


    I don't know these guys but when I was growing up I mowed grass in the summers for a retired couple that had one exactly like that in their garage. Always hoped to take it out. Never got the chance.

    Thanks for sharing!
    Some times my mind seems to wander..... these days I just tag along.

    Last time I saw an Amphicat, the Banana Splits were driving it! How's that for dating myself?

    Fun story, but really shows how one mechanical device can't do two things well.

    Looking on eBay I came across another http://cgi.ebay.com/ebaymotors/1969-Amphicat-6x6-Amphibious-ATV-Boat-Custom-Paint-COOL-/121047224454?pt=ATVs&hash=item1c2efa1086#ht_500wt_1023 device that floats and drives.

    Maybe we should throw a bid on it - would be a useful contraption for Nick and Kevin to carry their quadcopters to the runway about a quarter mile from the office. There's mud and a creek on the way.

    I don't know if they were Amphicats or not but when I was in my early twenties we used to see a few amphibious cars every summer at Wasaga beach (Georgian Bay, Ontario). Even got a ride once in a while.

    Nab it, Ken! That would be a great Parallax runabout at Expo!

    Maybe a better design? This one seems to work just fine, for over half a century

    Might be overkill for your creek, you might need to find a river.

    We have an Amphicar club in the Stillwater, MN area. I've seen as many as 4 of them on the St. Croix River on a fine summer afternoon.

    I actually rode in this RUC (River Utility Craft) once when I worked for the Army Corps of Engineers, doing summer hydrographic survey in the Carolina marshland circa 1980. Just found these pics at http://www.amphibiousvehicle.net/amphi/Ch_Ch.html

    Chrysler - River Utility Craft RUC (1969)

    Disappointing results in the Marsh Screw tests did not end ambitions for screw-type mobility systems.

    In 1969 Chrysler produced the Riverine Utility Craft (RUC) for the Navy. The RUC travelled on two aluminium rotors, 39 inches in diameter.

    Engine: twin Chrysler 440-cubic-inch auto-mobile
    Length: 7000 width: width: 4750 height: 3900 mm
    Weight 5900 kg
    Speed land: 50 km/h water: 28 km/h (WES test program in south Louisiana)

    Speeds on firm soils proved disappointing, 23 km/h maximum and only 6.5 km/h in MUCK.

    Screw vehicles failed big time compared with the more conventional wheeled and tracked vehicles.

    When I was in the Army, the survey platoon was issued the M-561 Gama Goat for field operations http://en.wikipedia.org/wiki/Gama_Goat.
    We were assured the vehicle was amphibious and periodically we were shown a film of a crew prepping and swimming the 'Goat. However, we were never required to do this and I never met anyone who actually did. If you asked any of the crews, the response was always something like "Are you f*****g kidding?!".

    On dry land tho', it was a blast to drive. There were few places you couldn't take a 'Goat and on field problems we took every opportunity to go boonie-truckin' in the little beast. ("Follow the tank trail? But Sarge, it's much closer cross-country!")

    New amphibious vehicle QuadSki at http://www.youtube.com/watch?v=9HQZ_t1MSWk&feature=player_detailpage#t=66s

    see also tightwalking robot just before that, and lots of other cool stuff in there.

    Just found this video of the RUC, as they called it in Charleston (re: 3 posts back).

  • There's a farm about five miles from me, that claims they deal in Argo amphibious. The signs been up for years. but I haven't ever seen any evidence of them.
  • I want to drive sideways through a swamp! That looks like fun.

    How's this for a set of wheels:

  • The paint just about completely weathered away, can't figure out if they were a dealer or just like them.

  • One of my old coworkers has an Argo 8x8. I think it would float, but he mostly cruises around dry land. He thought it was a big nicer to ride around in than an ATV. Maybe he just wanted an excuse to buy another toy. The bad thing is that people sitting in the back can get whipped around a bit due to the slip steering.

    I would have never guessed the cameras were in the holes in the roof rack. The image on the screen looks decent for a sensor that small. I wonder where the IR illuminators were hidden. If those are light amplification cameras they'd be worth quite a bit more than the van.

    My guess is they wouldn't want IR illumination to give them away, in case someone had the tech. In twenty years we get this trickle down, what do you do with, it other than scare your neighbor.

    Not to forget about the Chinese amphibious ATV.

    They seem to take it a little too serious though.

    Also over crowding is dangerous, and limits the ability to just have fun.

    The British Army used to operate these. Absolutely fantastic machines, one of which I was lucky enough to drive. One even went across the English Channel (at which point the French thought they were being invaded and surrendered).

    Amphibious cars are made just down the road from me.
