I was fortunate enough when studying mechanical engineering to get to learn programming on some robotic arms.
These are very precise and powerful, coming in at a cool $250 000 each.
We programmed them to draw pictures with a pencil, do welding operations, assembly, Manufacturing operations... You can basically get them to do what ever your arm can do but with over 1000x the strength and accuracy.
Until next time

advance engineering.
