- stcredzero 8y agoLots of people in the robotics field might be making such an observation. Hopefully, this won't also apply to many production self driving vehicles.
- otakucode 8y agoThe first fully self-driving car to market will be from the company that cuts the most corners and compresses schedules the most. I'm sure it will be fine.
- stcredzero 8y agocuts the most corners and compresses schedules the most Only works for well-trodden paths where everyone is doing basically the same thing. Does this apply to self driving cars?

- sp332 8y agoSo if this fell on someone, would it electrocute them?
- godelski 8y agoDepends on a lot of things. But a big one is the amperage used. There's a parallel frequently used. Voltage is the reach, and amperage is how hard you can hit. This is why a lot of Tesla's demonstrations weren't fatal to people (and being high frequency). This device, probably not using high amperage anywhere that would really matter. But they are pulling high amps from the batteries, which is then converted to high voltage. So there is a distinct possibility that it could kill someone. But not likely in this small of a form factor.
- clort 8y agoI'm guessing not. More like an electric fence: volts are high but current is low.
- hermitdev 8y agoVoltage doesn't kill, current does. One can easily take 10s of thousands of volt across the the heart if the amperage is low, but a car battery putting out 12 volts and several amps can. Personally, I've taken leads from a 240V, 3KW solar panel array from hand to hand and not felt a thing. Have so same 2 leads touch the same hand, you're going to feel it. For me, felt like a snake bite, minus the venom. Left a few small red mark on my hand that cleared up in a few days. Mind this is all in reference to DC current. AC is another beast.
- hermitdev 8y agoEdit: it takes around, or less, than 1.5 mA across the heart to kill
- darkmarmot 8y agoAt 40kV and 600 watts, it's 15mA, so yes, it could definitely stop their heart...

- osrec 8y agoI find engineers are generally passionate, interesting people to be around, especially if they're masters in unintentional, deadpan humour.
