You need sensor input. It doesn’t have to be visual imagery. Simple single datum sensors are much easier to work with.
Regarding arms and tooling, I understand now where you are coming from. He has a list of tools (CNC mill, lathe) that I wouldn’t necessarily call “hand-tools.” In almost all instances these are automated in factories without the use of robotic arms, and certainly not advanced dexterous capabilities.
He lists a robot with two arms at the beginning, but I took that to mean a simple three-segment arm in the mechanical engineering sense, which is capable of 6DOF motion, and a gripper to hold things in place. This is the minimal you would need for simple, straight-forward tele-operated assembly steps. And it would be used solely for assembly—the machines would use their own locking mechanisms to hold the part in place.
As I said though, with some proper thought into part design you don’t even need the three-segment robot arms, A gantry or Stuart platform would be sufficient.
Finally, the electronics are taken as vitamins to the system. You send a shipping container full of actual raspberry pi’s.
I was actually thinking of a pair of humanlike arms with many degrees of freedom, and one or more cameras looking at things. You can have dozens of single datum sensors, or one camera. It’s much cheaper. Similarly, once you have some robot arms, there’s no gain in including many single use motors. For example, when I include an arbor press, I don’t mean a motorized press. I mean a big lever that you grab with the robot arm and pull down, to press in a shaft or shape a screw head.
There are two CNC machine tools, to automate some part shaping while the robot does something else.
It is not at all obvious to me that one camera is “cheaper” than dozens of single datum sensors. The camera requires complicated, expensive, and error-prone image analysis software. The single datum sensor can be a simple PID control mechanism in a microcontroller.
Load up a video of a manufacturing or assembly line, and count how many human-dexterous robotic arms are in use. In most cases, you’ll find zero. Even 3D printers and CNC machines, which are supposed to be general-purpose, find no need for the complexity of an industrial arm, let alone something comparable to a human arm.

We don’t build machines that way for a reason.
