Gears are the main method of circular motion since the dawn of time, and a huge part in horology (which nowadays is a study of and a hobby of collecting timekeeping devices). However, you will tend to see more gears in mechanical watches than quartz watches.
That varies. Different devices are designed differently. Somewhere on outside (usually on the back) of every electrical device there should be a kind of permanent sticker stating the voltage and current it uses.
A robotic device can do whatever it's designed to do. There are robotic devices that are designed to paint vehicles in an automobile manufacturing facility, and those robotic devices simply paint vehicles. There are robotic devices that are used to cut metal shapes and others that are designed to cut wooden shapes. There are robotic devices that are used to laser etch, and others that are designed to carve shapes. So far, there are no true "general purpose" robotic devices.
All devices can work, if they are designed properly and are well-maintained.
