Parts of a robot

Even though Shakey was built 50 years ago, it still had the basic components of a mobile robot. That is:

Newer robots may also have features like

Batteries are a surprisingly critical part of the design. Even now, they are heavy compared to how much power they deliver. So they can be a significant percentage of the robot's weight.

A robot usually has several redundant sensors because they fail in different ways, e.g. whiskers operate only at very short distances, IR sensors fail on dark surfaces.

There is a tradeoff between extra features and better safety. Robots working close to humans have to be less ambitious so that they are more reliably safe.
