Do you know if anybody is working on a spider / walking bot?

I was looking at the farmbot and thinking a version with 20" bicycle wheels would be better. Then you could have a long path where it just moves back and forth. And maybe use a robot arm based on rotating arms instead of linear actuators. And then build the whole thing so it fits neatly under a big glass solar panel. Maybe a tool changer so it can pick up a watering can. The mechanical side should be relatively easy to build, the problem still seems to be the AI vision software.

With food prices rising it might be worth it if you can increase the area it can patrol.
