Robot: n. an unmanned autonomous machine. (Your plastic pal who's fun to be with).

Mission statement

  1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
  2. A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
  3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.
What could possibly go wrong?

"Dave, I think you know what the problem is, just as well as I do."

Disclaimer

Clearly the author takes absolutely no responsibility for anything dangerous, illegal, destructive, immoral or just plain stupid that anyone does with these notes. Just a word of caution: 40kg robots are dangerous. 200kg petrol-powered robots with blades spinning at 200km/h are almost unstoppable. Think about a small person getting rammed at full speed with one of these. It will make The Walking Dead seem like a romantic chick flick. Think. Please.

The future

Using ROS2. This is a big challenge just in itself.
Weed Detection. Mounting a face-down camera and analyzing the image to detect weeds.
Weed Removal. Either through spraying or mechanical means (a length of wire like a lowering spring on a motor can dig out weeds without chemical environmental damage).
Pest Eviction. Chasing the kangaroos out of the yard (and maybe out of the paddocks, if kangaroos can be differentiated from sheep and alpacas ).

Conclusion

"I'm sorry Dave, I can't let you do that."

Think I might have solved your problem? Ninety-nine problems, but your robot ain't one? Say so ..
