@georgetakei holy crap that thing is dangerous.
No big friendly E-Stop. Doesn't trip out and shut down the motor drivers when encountering resistance. Can't be overpowered by staff. Rapidly swings appendages. Deployed in an environment where the general public can get up close and personal.
This is a recipe for disaster. It doesn't know you're there, it doesn't know it's own strength, and it won't stop just because it's broken bone.
