Using gears, levers, pulleys, and ramrods, corporations have been able to create many devices. When made out of an acid-resistent substance that can withstand high pressure, a mechanical machine may work. The only problem with a mechanical machine is that once on the planet, sure it can do work, but it would be unable to transmit and data findings back to a receiver on a ship or earth. There would be a point where some sort of electronics would be needed. And as of right now, there is not an effective enough invention that could put humans on Venus to live and research.
