I've been watching this little robot on Facebook for months now. I'm disappointed that it ends this way.
There's always someone, somewhere, who ruins the good stuff for no good reason. Hopefully, there is something that can be learned for future efforts. If it were me, I would put some nasty stuff in there to protect the robot from vandals!
What we need is a robot that is virtually indestructible by all but the most intelligent humans. The idiots will get tased, or something more severe.
