Most people go the easy route and buy a "Vex Robotics" kit. We built
our own and won.

This robot works like a skid steer. The bucket, I made sharp as a
knife and sharpened it to make it a straight and sharp blade, on a
surface grinder.

Sorry, the purpose of a very sharp bucket edge is to pick up pennies
and Lego bricks, that are hard to pick up otherwise.

Thanks. No, the whole school teams compete in nationals, and our team
did not get enough winning points.

A hearty congratulations to you guys, Ig. Way to go!

It looked like the cord had some interference a couple times. Thinner,
more flexible wire is available for CNC use, so you might think of
having him replace that before the next run.

Yeah, congratulations sir. I figure an engineering scholarship down the road for your son. Or he'd be one ace backhoe driver in the interim.

I did not find anything better. I needed 8 conductors. I also recently
scrapped a big gaylord box of scrap CNC wire, did not have much, but
most such things are actually thicker and less flexible than Ethernet
cable.

Excellent!, and in the third picture, you can clearly see a minor injury to his left thumb. He's well on his way to becoming a tool junkie.

To get the cable more flexible, you could strip off the outer jacket, remove whatever strings are inside, and braid (a little bit loosely) the wires together. Another advantage of that is that you end up with a cool multi-color cable.

So what's next? Drop in an arduino & joystick and do proportional control? Drop an arduino in each end, add some RF and do away with the cable altogether?
-or-
Just build a bigger one? The learning possibilities are endless.
