Electric cars are wonderfully simple and nice. They are: Battery -> controller -> motor -> wheels. No grease, no oil, no mess. Even when you run out of battery, it is not like running out of gas. You can still get off the road. The problem is the battery does not have much capacity, compared to gaso...

Re: AC Motor Control
I am buying a Toyota Prius. Its electric motors run on 500 volt AC. Its battery pack is 206 volts The electric motor also charges the battery pack when coasting. I thought it was time to go Tesla and learn AC motors. Now we have IGBTs to make inverters, but I don't know how to use them. I don't know...

Re: underwater ROV
In the early 60's I worked on a tethered underwater vehicle for the Navy. It was never bought and there are better ones now. This used two cylinders, one above the other with motors on outriggers between. A cable connected all this to the ship. I had fun dragging a garden hose in the Potomac(sp) riv...

Re: Underwater Robotics
Back in 1956 I worked on a vehicle like that for the navy. People are still working with the same concepts. This had a tether with camera and control. It was supposed to destroy mines.
It is an interesting area. I just don't have any handy water right now.
