That's an awfully optimistic anatomical statement when we're talking about robotic snakes. Just saying.

I just realized that this is a "dual-use" technology, if you know what I mean.

Probably a coincidence: http://cleantechnica.com/2015/05/06/teslas-next-big-supercha...

...probably.

Really? Is the need to get out and hook up the hose yourself really what's holding back electric cars? There is certainly a cool factor with this thing, but think about how it will work at a real fuel/charging station. The driver will only ever see it in a mirror. And it looks like the range of motion is very limited, requiring the plug to be within a 30x30cm box. A later model will probably have a greater range of m…

While most if not all "concept technology" has its roots in the "we can do it, even if we don't know why we should" school of thought, I imagine this will be valuable for self driving cars. Imagine a car that can drop you off at work, drive itself to the closest robo-charger, and return to pick you up with a full charge, all without needing an attendant. Given the current limited range of EVs, tech like this will lik…

That's how we end up with inflatable bbqs. This really looks like a rich person's toy, of no practical use.

Many people have talked over the years about self-driving cars dropping people off and heading home. That sounds great in terms of the number of parking spots, and might make sense in cities where parking costs more than rent, but I cannot see how doubling the number of trips can reduce traffic congestion. The far simpler solution would be to install simple (ie cheap) chargers at each parking spot.

> We are wired to be afraid of snakes and snaky things Are we really wired for it, though? I've personally never had that fear. Perhaps it's a little more nurture than nature?

"Experiment 1 results indicated that observer rhesus monkeys acquired a fear of snakes through watching videotapes of model monkeys behaving fearfully with snakes. In Experiment 2, observers watched edited videotapes that showed models reacting either fearfully to toy snakes and nonfearfully to artificial flowers (SN+/FL-) or vice versa (FL+/SN-). SN+/FL- observers acquired a fear of snakes but not of flowers; FL+/SN…

So, is it obvious that monkeys aren't afraid of snakes if they never see other monkeys act afraid before? Because that's what I'd test first.

Further, if there's a learned fear of snakes, that might not be coincidence, even if it's not genetic.

I bet if you exposed another mammal like a monkey or a cat to that recharging tentacle, it would be frightened by it too. We are wired to be afraid of snakes and snaky things. It's one of the most common phobias. Sci-fi horror merely tapped into that fear.

I wonder what fail safes it has to manage someone driving off with the arm attached. Like the terminator hanging from the side of the car swinging around like crazy. Can't wait ro see it in action. I know Shell petroleum worked on a similar system for gasoline cars around the year 2000. It was deemed too risky to use.

Kids and adults are OK with stuffed lions and tigers. How does that fit in with the wiring theory?

It just suggests that we've evolved fears of some, but not all, things which are dangerous to us?

An analogy might be, many people are afraid of heights, and fewer people are afraid of water. That's despite the fact that water is also dangerous. But none of this proves or disproves the notion that fear of heights may be "hardcoded".

The car won't shift out of park if there's anything in the charge port.

Edit: regarding the Shell attempt, one great thing about EVs is how safe they are to "refuel." You can literally have a four year old do it. I have.

Nice. Robotic fueling has been done before [1][2], but this is much less clunky. This looks like the OC Robotics snake robot.[3] Finally, a use for snake robots, which have been around for 25 years but are not used much. Tesla has a good application for this - the car end is cooperative and standard. The car's parking guidance system can be programmed to recognize visual targets and get itself into the proper positio…

Call me a pessimist but I look at that thing and I see it breaking. Drive over it, vandalism, one of the hundred little motors having a defect... Why not just have two or three axis of movement in a more static, 90° construction??

That could probably be made to work today, with the gear used by container cranes to slot containers onto ships, trucks, and railroad cars. It would be more complicated than the snake, because stabilizing a hanging load is hard. Once in a while it would probably scratch the car body. What a lot of people here aren't getting is that snake robots are mechanically simple. They're unusual, but neither complex nor expensi…

Would the claw still work if it was coated in soft rubber? Alternately, I'm imagining the cute-but-ridiculous solution of making the claw and the car magnetically repel one another, so as it the claw plumb-bobs downward and swings toward the car, it just sort of naturally veers away from the surface, rocking around it in an arc until it stabilizes.

Make it so that the magnet is recessed inside a rim of soft plastic or rubber. Then it will still be able to slot onto the charge port but will not be able to hit the car body.
