You and me - staring at our computer screens.
There are a great many things in the world that are being done to save Pandas. Shirts are being sold to raise money for this purpose for example.
Most of the modern imaging from space is done with optical lenses with CCD's, charge coupled devices. See link below.
An example of work being done on an object is when a painter paints a canvas. The canvas is the object on which the work of painting is being done. The action of applying paint to the canvas is the work being performed on the object.
Sony corporation of Japan has created ASIMO as an example of what is being done in Robots. They will be able to help you understand the details of what is being done in that field
One example of positive work being done in physics is the development of renewable energy technologies, such as solar panels and wind turbines, to address climate change and reduce reliance on fossil fuels.

It cannot be done, sorry. That is one of the features that Einstein had to deal with in coming up with his relativity theory. There is no way to tell if the Earth is spinning, orbiting the Sun, etc . . . there is nothing that prohibits the entire universe from rotating around a fixed Earth. So, we choose to say that Earth moves, not absolutely, but relative to the other heavenly bodies around us.
